Step 1: Understand Decentralized Identity and Its Unique Threats

Before we can secure something, we need to understand what it is and what we’re protecting it from. Decentralized Identity (DID) puts you in the driver’s seat of your online persona. Instead of relying on a company to store your data and manage your access, you hold your own unique identifiers and digital proofs, directly controlling how and when they are used.

What Exactly is Decentralized Identity?

• Decentralized Identifiers (DIDs): These are unique, user-owned digital IDs that you control, not a central company or government. Think of it as a permanent digital username that is truly yours, without a central authority that can take it away or track your activity through it.
• Verifiable Credentials (VCs): These are tamper-proof, digital proofs of your attributes, much like a physical driver’s license, a university diploma, or a professional certification. Trusted entities (issuers) digitally sign them, and you store them securely in your digital wallet. The power lies in selective disclosure: you choose precisely who to share them with and when, revealing only the necessary information. For example, proving you’re over 18 without revealing your exact birth date.
• Digital Wallets: These are secure applications on your device (or in specialized hardware) where you store and manage your DIDs and VCs. They’re the secure hub of your decentralized identity, acting as your personal digital safe and interface for interactions.

Common Threats to Your Decentralized Identity

While DID offers significant advantages in privacy and security, it shifts the responsibility. New types of threats emerge that you, the user, must actively defend against.

• Digital Wallet Compromise: This is akin to someone stealing your physical wallet, but with potentially far greater consequences. If your device (phone, computer) is lost, stolen, or infected with malware, an attacker could potentially access your digital wallet. For instance, if you fall victim to a sophisticated phishing attack that installs a keylogger on your computer, your wallet’s access PIN could be captured, granting unauthorized access to your DIDs and VCs.
• Private Key Theft/Loss: Your private keys (often represented by a “seed phrase” or “recovery phrase”) are the absolute “keys to your kingdom.” Losing them means losing access to your identity and associated assets forever; having them stolen means someone else controls your digital self. This is often irreversible. There are countless cautionary tales in the crypto world of individuals losing access to millions because they lost or improperly stored their seed phrase, a lesson that applies equally to DID.
• Phishing and Social Engineering: Attackers will cunningly try to trick you into revealing your private keys, seed phrase, or approving malicious transactions. This often happens through fake websites, deceptive emails, or misleading messages that mimic legitimate services or people you trust. Imagine receiving an email seemingly from your digital wallet provider, warning of a “security breach” and asking you to “verify your identity” by entering your seed phrase on a fake website. One wrong click, and your identity could be compromised.
• Vulnerability in Issuers or Verifiers: While DID reduces central risk, issues can still arise if the entities issuing or verifying your credentials have their own security flaws. If an issuer’s system is compromised, a malicious actor might forge or revoke credentials, undermining the trust in the system. While you control your DIDs, if the university that issued your digital diploma (VC) has a data breach, the integrity of some of your credentials could be called into question, even if your wallet remains secure.

Instructions:

• Take a moment to truly understand the three core components: DIDs, VCs, and Digital Wallets. Their interplay forms the foundation of your decentralized identity.
• Familiarize yourself with the unique threats to these components. Your security journey begins with awareness and understanding the specific weaknesses an attacker might exploit.

Code Example:

While securing your identity doesn’t involve traditional code, understanding the format of a DID can be helpful:

did:example:123456789abcdefghi

(This is a simplified example. Real DIDs have more complex structures and methods, incorporating specific “DID methods” like did:ethr or did:web.)

Expected Output:

A clear mental model of how your decentralized identity works, a solid grasp of its core components, and an acute awareness of the primary risks it faces.

Tip: Think of your digital wallet as your actual wallet, and your private keys/seed phrase as the master key to everything inside it. If you wouldn’t give someone your physical wallet or its master key, you should treat your digital one with even greater caution.

Step 2: Fortify Your Digital Wallet with Strong Access Controls

Your digital wallet is the central hub for your DIDs and VCs. Securing it is your absolute top priority. This is where we bring robust “password management” and physical security principles into the decentralized world.

Instructions:

• Choose a Reputable Digital Wallet: Do your research meticulously! Look for wallets with strong security features, positive community reviews, transparent open-source development (if possible), and a clear track record of security audits. Consider factors like its support for various DID methods, user interface, and the reputation of the developers. A hastily chosen wallet can introduce unnecessary risks.
• Implement Strong PINs/Passwords: Most digital wallets require a PIN or password to unlock them on your device. Just like your bank account, this needs to be unique, strong, and not reused anywhere else. Use a complex combination of letters, numbers, and symbols. Leverage a reputable password manager to generate and store these complex passwords for your wallet’s access. For a deeper dive into modern authentication, consider exploring passwordless authentication approaches.
• Master Your Private Keys (Seed Phrase): This is the most critical step, the single point of failure for your entire decentralized identity. Your private keys (often presented as a 12- or 24-word “seed phrase”) are the ultimate proof of ownership. If someone has your seed phrase, they own your identity. If you lose it, you lose access to your identity forever.
• Understand the Difference: Your public key (or DID) is like your bank account number – you can safely share it for others to send you information or verify your credentials. Your private key (seed phrase) is like your bank account password and PIN combined – you must never share it with anyone, under any circumstances.
• Backup Securely and Offline: The golden rule: Write down your seed phrase on paper or engrave it on metal. Make multiple copies. Store them in physically secure, fireproof, and waterproof locations, such as a home safe, a safe deposit box at a bank, or with a trusted family member (with appropriate security protocols, like splitting parts of the phrase). NEVER store it digitally (on a computer, cloud storage, email, or a photo on your phone) where it can be hacked or retrieved by malware.
• Treat it like Gold (or more): Never take a photo of it, email it, text it, or type it into any website unless explicitly required by your wallet for recovery on a fresh, secure device you fully trust. Be extremely wary of any service, website, or individual asking for your seed phrase. Legitimate services will almost never ask for this.

Code Example (Seed Phrase Format):

Your 12- or 24-word seed phrase (example):

apple banana cherry date elder fig grape honeydew ivy jackfruit kiwi lemon

(Remember, never use this example phrase; always generate your own unique phrase and keep it absolutely secret.)

Expected Output:

A carefully chosen, reputable digital wallet protected by a strong access PIN/password, and your seed phrase securely backed up offline in multiple, redundant, and physically secure locations.

Tip: Consider using a password manager for your wallet’s access password (the one you type to unlock the app). For your seed phrase, however, physical security and diligent offline storage are paramount. This separation of digital and physical security layers is crucial.

Step 3: Activate Multi-Factor Authentication (MFA) for Wallet Access

Multi-Factor Authentication (MFA) adds an essential extra layer of security beyond just a password or PIN. Even if an attacker somehow obtains your primary password, MFA acts as a critical barrier, requiring a second, distinct piece of evidence of your identity. For decentralized identities, this typically involves biometrics or dedicated hardware keys.

Instructions:

• Enable Biometrics: If your digital wallet app supports it (and your device does), enable fingerprint or face ID to unlock your wallet. This provides a convenient and strong second factor, as your biometric data is unique to you. A quick scan of your thumb or face is far more secure than a simple PIN that could be observed or guessed.
• Explore Hardware Wallets: For critical DIDs, high-value verifiable credentials, or any associated digital assets (like cryptocurrencies), consider using a hardware wallet (e.g., Ledger, Trezor). These devices physically store your private keys in an isolated, secure chip and require a physical button press to approve transactions. This makes them extremely resistant to online attacks, as your private keys never leave the device. A hardware wallet is like a high-security vault for your digital identity, insulating your most valuable secrets from the vulnerabilities of your internet-connected devices.
• Understand Software-Based MFA: Some wallets might integrate with authenticator apps (e.g., Google Authenticator, Authy) for access. Always use these if available, as they generate time-sensitive codes that add another layer of protection compared to SMS-based MFA, which can be vulnerable to SIM-swap attacks.

Code Example (Conceptual MFA Setup):

# Example of enabling biometrics within a wallet app's settings

Security Settings > Enable Fingerprint Unlock: [Toggle ON]

Expected Output:

Your digital wallet configured with at least one form of MFA, such as biometrics or a hardware device, significantly increasing its security and resilience against unauthorized access.

Tip: While convenient, biometrics are tied to your device. For the ultimate security, a hardware wallet offers superior protection by isolating your keys from your online device entirely. Always prioritize the highest form of MFA available for your digital wallet.

Step 4: Secure Your Connection When Managing DIDs

While a VPN doesn’t directly secure your decentralized identity components (like your seed phrase), it plays a crucial role in securing the environment in which you interact with them. Think of it as protecting the road you drive on to get to your secure digital safe.

Instructions:

• Use a Reputable VPN (Virtual Private Network): Always use a trusted VPN, especially when connecting to public Wi-Fi networks (e.g., cafes, airports, hotels) to manage your digital wallet or interact with DID services. A VPN encrypts your internet traffic, creating a secure tunnel that prevents eavesdroppers (like malicious actors on public Wi-Fi) from seeing what you’re doing, the websites you visit, or the data you transmit. Using public Wi-Fi without a VPN is like having a private conversation in a crowded room with open microphones; anyone can listen in on your digital transactions.
• Avoid Free VPNs: Many free VPNs compromise your privacy by selling your data, injecting ads, or offering subpar encryption. Invest in a paid, reputable VPN service with a strong no-logs policy and a proven track record. Your digital identity’s security is worth the small investment.
• Keep Your VPN Active: Make it a habit to turn on your VPN whenever you’re doing anything sensitive online, including managing your decentralized identity. Consider setting it to automatically connect when you’re on untrusted networks.

Code Example (Conceptual VPN connection):

# Example command for connecting to a VPN via a client (conceptual)

vpnconnect --server mytrustedvpn.com --username myuser --password mypass

Expected Output:

A secure, encrypted network connection whenever you are interacting with your digital wallet or DID-related services, especially on untrusted public networks, protecting your data from interception.

Tip: Even at home, a VPN can add an extra layer of privacy by obscuring your IP address from websites you visit. Always ensure your VPN software is updated to benefit from the latest security patches.

Step 5: Practice Secure Communication and Sharing of Verifiable Credentials

One of the core promises and greatest strengths of decentralized identity is selective disclosure – the ability to share only the absolute minimum necessary information. This is where “encrypted communication” and careful scrutiny come into play, not just for messages but for your precious VCs too.

Instructions:

• Be Selective with Sharing: Only share the verifiable credentials, or specific attributes from them, that are absolutely necessary for the interaction. For example, if a service only needs to know you’re over 18, don’t share your full date of birth. DID systems often support powerful “zero-knowledge proofs” which allow you to cryptographically prove an attribute (like being over 18) without revealing the underlying data (your actual birth date). Embrace this power: don’t overshare just because you can.
• Understand the “Who” and “Why”: Before sharing any credential, take a moment to understand exactly who is requesting it (the verifier), why they need it, and what they will do with it. Don’t blindly approve requests. Legitimate verifiers should be transparent about their data requirements. Think of it like being asked for your ID: you wouldn’t hand it over without knowing who’s asking and why.
• Use Secure Communication Channels: If you ever need to discuss your DID security or specific credentials with a trusted advisor, always use end-to-end encrypted messaging apps like Signal or ProtonMail, rather than standard email, SMS, or unencrypted chat services. These channels protect your sensitive conversations from eavesdropping.

Code Example (Conceptual Credential Sharing Approval):

# Example of a minimal credential sharing approval in a wallet app

{ "request": "Prove age > 18", "data_shared": { "is_over_18": true }, "recipient": "example-verifier.com" }

Expected Output:

A mindful and deliberate approach to sharing your verifiable credentials, disclosing only essential information, and leveraging secure communication for any sensitive discussions related to your digital identity.

Tip: Always look for the specific attributes being requested by a verifier. A well-designed DID system will allow you to share only what’s absolutely needed, minimizing your data footprint and enhancing your privacy.

Step 6: Harden Your Browsing Environment for DID Interactions

Your web browser is often the primary gateway through which you interact with various online services, including those that might integrate with your decentralized identity. A secure and well-configured browser is a foundational layer for DID security, just as a strong lock protects your front door.

Instructions:

• Use Privacy-Focused Browsers: Consider browsers like Brave, Firefox (with privacy-enhancing add-ons like uBlock Origin and HTTPS Everywhere), or Tor Browser for highly sensitive activities. These browsers are often built with privacy in mind, blocking trackers, intrusive ads, and having built-in features to reduce your digital fingerprint.
• Be Cautious with Browser Extensions: While extensions can be incredibly helpful, they can also be malicious or introduce significant vulnerabilities. Audit your installed extensions regularly. Be extremely wary of any extension that requests broad permissions like “read and change all your data on websites” or claims to interact directly with your crypto/DID wallet (unless it’s an official extension from a highly trusted, reputable wallet provider). A compromised browser extension can act as a spy or a backdoor, siphoning off your sensitive data or redirecting your transactions without your knowledge. Only install essential, highly-rated extensions from trusted sources.
• Keep Your Browser Updated: Ensure your browser is always running the latest version. Software updates often include critical security patches that fix newly discovered vulnerabilities that attackers could exploit. Enable automatic updates whenever possible.

Code Example (Conceptual Browser Security Setting):

Browser Settings > Privacy & Security > Enhanced Tracking Protection: [Standard/Strict]

Expected Output:

A web browsing environment that minimizes privacy risks and significantly reduces the attack surface for potential exploits targeting your digital identity interactions, creating a safer space for your DID activities.

Tip: Consider using a dedicated browser profile or even a completely separate browser installation solely for managing your decentralized identity. This isolates your DID activities from your general browsing, significantly reducing the risk of cross-contamination from less secure sites or extensions.

Step 7: Safeguard Your Digital Presence Beyond Your Wallet

While your decentralized identity components are key, your overall digital hygiene and online presence still matter immensely. Attackers often leverage information gleaned from your broader online presence (“Social Media Safety”) to launch highly targeted phishing or social engineering attacks against your DID, even if your wallet itself is secure. It’s crucial to Fortify Identity Against AI Threats, as they are increasingly sophisticated.

Instructions:

• Review Social Media Privacy Settings: Limit the amount of personal information visible to the public on platforms like Facebook, Twitter, and LinkedIn. The less an attacker knows about your interests, family, and habits, the harder it is for them to craft convincing phishing attempts or social engineering schemes tailored specifically to you. A seemingly innocent post about your new decentralized identity wallet could be used by an attacker to impersonate a “support agent” later on.
• Be Skeptical of Unsolicited Contact: Be highly suspicious of anyone contacting you out of the blue, especially if they mention decentralized identity, offer unsolicited help, ask for personal details, or urge you to click links or “verify” information. This is a classic social engineering tactic. Always verify the sender through an independent, trusted channel.
• Educate Yourself on Common Scams: Phishing and social engineering techniques constantly evolve. Stay informed about current scam trends, especially those related to crypto, blockchain, and digital identity. Regularly check reputable cybersecurity blogs (like ours: passwordly.xyz blog) and security news sources. Knowledge is your best defense against deception.

Code Example (Conceptual Privacy Setting):

Social Media Profile > Privacy Settings > Who can see my posts: [Friends Only]

Expected Output:

A reduced digital footprint that makes you a less attractive or easier target for social engineering attacks, ultimately strengthening the security posture of your decentralized identity.

Tip: Use unique, strong passwords for all your online accounts, not just your digital wallet. A breach on a seemingly unrelated account (e.g., your email or social media) could still be used to gather information about you, reset other passwords, or launch a more sophisticated attack against your decentralized identity.

Step 8: Embrace Data Minimization with Your Verifiable Credentials

Data minimization is a core tenet of privacy, and it’s intrinsically supported by decentralized identity. It means collecting, storing, and retaining only the personal data absolutely necessary for a specific purpose. For you, this translates into carefully managing your VCs and the information they contain.

Instructions:

• Only Present What’s Necessary: As discussed in Step 5, leverage zero-knowledge proofs if your wallet and the verifier support them. Always opt to share the smallest possible subset of information. For instance, if a website only needs to confirm you’re an adult to access content, don’t show them your exact birth date – simply present a proof that you’re over 18. This principle significantly reduces your exposure.
• Regularly Review Access: Many advanced DID systems provide a dashboard or log of which verifiers you’ve shared credentials with, when, and for what purpose. Make it a habit to regularly review these permissions. This is your personal audit trail for data sharing.
• Revoke Access When No Longer Needed: This is a critical and often overlooked feature! If you no longer use a service, or if you suspect a verifier might have been compromised, use your wallet to revoke its access to your verifiable credentials. This prevents them from continuing to access or verify that specific piece of information. Think of it like cancelling a subscription. If you’re not using a service, why keep giving it access to your data? Actively managing your revocations empowers you to cut off data streams you no longer approve of.

Code Example (Conceptual Revocation Command):

# In a wallet interface, you might see an option like:

{ "credential_id": "credential-id-12345", "action": "revoke_access", "verifier_id": "example-verifier.com" }

Expected Output:

A lean and secure digital identity, where your personal data is only shared with trusted parties for specific, limited purposes, and access can be promptly terminated when no longer needed or if a risk arises.

Tip: Always look for wallet features that allow granular control over credential sharing and prompt revocation. This active management is a cornerstone of maintaining privacy and security in the decentralized identity ecosystem.

Step 9: Implement Secure Backup Strategies for Your Private Keys

We touched on this in Step 2, but it’s so vital it deserves its own dedicated step. Your private keys (seed phrase) are the single point of failure for your decentralized identity. Proper, redundant backup is non-negotiable for recovery and resilience.

Instructions:

• Physical, Offline Storage is King: Write down your 12- or 24-word seed phrase on high-quality, durable paper using a permanent marker, or engrave it on a metal plate. Avoid any digital format for storage whatsoever (no photos, no text files, no cloud uploads, no emails). This “air-gapped” approach protects your keys from online hacks and malware.
• Multiple, Geographically Separated Copies: Don’t put all your eggs in one basket. Store at least two, preferably three, copies in different physical locations. Consider a fireproof safe at home, a safe deposit box at a bank, or a trusted friend’s or family member’s secure location (with clear instructions and appropriate physical safeguards like a tamper-evident bag). If a house fire or natural disaster occurs, you need to know you have another way to recover your identity.
• Protect Against Physical Threats: Your backup needs to be resistant to common physical threats like fire, water, and physical damage. Metal plates or laminated paper stored in waterproof containers are excellent choices.
• Test Your Recovery Process (Carefully): If your wallet allows for it, perform a “dry run” recovery with a small amount of value or a test DID on a new, clean device to ensure your seed phrase is correct and you fully understand the recovery process. Never do this with your main wallet on a device you don’t fully trust or one that might be compromised. This test confirms your backup works.

Code Example (Conceptual Seed Phrase Backup):

# Your 24-word seed phrase (NEVER store digitally, this is for format example)

alpha bravo charlie delta echo foxtrot golf hotel india juliet kilo lima mike november oscar papa quebec romeo sierra tango uniform victor whiskey xray

Expected Output:

A robust, physically secured, and redundant backup strategy for your seed phrase, ensuring that even if your primary device is destroyed, lost, or compromised, you can recover full access to your decentralized identity and its associated assets.

Tip: If you have a significant amount of value or critical verifiable credentials tied to your decentralized identity, consider a hardware wallet for primary storage and, for advanced users, explore multi-signature schemes if supported by your DID method for an even higher level of security against a single point of failure.

Step 10: Adopt a Threat Modeling Mindset for Your DID Ecosystem

Threat modeling is a proactive security exercise where you identify potential threats, vulnerabilities, and counter-measures before an incident occurs. It’s about thinking like an attacker to better protect yourself, turning reactive panic into thoughtful prevention.

Instructions:

• Identify Your Assets: What are you trying to protect within your decentralized identity ecosystem? This includes your DIDs, your specific VCs (e.g., your digital driver’s license VC, your diploma VC, your professional certification VC), your private keys/seed phrase, and your digital wallet application. Prioritize these based on their importance to you.
• Identify Potential Threats: Who might want to attack you and why? (e.g., individual hackers, organized crime, state actors). How might they attempt to do it? (e.g., phishing campaigns, malware installation, physical theft of your device or backup, social engineering tactics). Consider both online and offline threats.
• Identify Vulnerabilities: Where are your weak points? Is your seed phrase stored in an easily discoverable location? Is your device running outdated software? Do you have weak passwords on other accounts that could be used for reconnaissance? Is your anti-malware software up to date?
• Devise Counter-Measures: For each identified threat and vulnerability, what specific, actionable steps can you take to mitigate the risk? (Many of these steps are covered in the previous sections!). For example: If a threat is “physical theft of my phone,” and a vulnerability is “easy access to wallet via simple PIN,” then a counter-measure is “enable biometric unlock and consider a hardware wallet for high-value DIDs.”
• Consider Your Use Cases: How do you *currently* use your decentralized identity? What specific interactions (e.g., logging into a service, presenting a credential, receiving a new VC) might expose you to unique risks? Tailor your threat model to your real-world usage.

Code Example (Conceptual Threat List):

# Example entries in a personal threat model

Asset: Seed Phrase Threat: Physical theft from home Vulnerability: Stored in easy-to-find drawer Counter-Measure: Secure in fireproof safe, off-site copy Asset: Digital Wallet App Threat: Malware on phone Vulnerability: Outdated OS, no biometrics Counter-Measure: Keep OS updated, enable fingerprint unlock, use hardware wallet for main DIDs

Expected Output:

A personalized understanding of your unique risks within the decentralized identity landscape and a tailored, proactive security plan to mitigate them, fostering a continuous, vigilant approach to your digital security.

Tip: Regularly revisit and update your threat model, especially as you start using new DID services, acquire more verifiable credentials, or when new threats emerge. Security is not a one-time setup, but an ongoing process.

Step 11: Prepare for the Worst: Incident Response for DID Compromise

Even with the best precautions, things can go wrong. Having a clear incident response plan for your decentralized identity is crucial. This is your “data breach response” for the DID world, ensuring you can act swiftly and decisively to minimize damage.

Instructions:

• Identify Compromise: How would you know your wallet or a credential has been compromised? Look for unauthorized transactions, inability to access your wallet despite correct credentials, warnings from credential issuers or verifiers, or suspicious activity on linked accounts. Trust your instincts if something feels off.
• Isolate and Assess: If you suspect compromise, immediately disconnect your device (phone, computer) from the internet to prevent further unauthorized activity. Do not interact further with the compromised wallet or device. Try to calmly determine what exactly was compromised (the wallet app itself, a specific credential, your private keys/seed phrase, or a linked account).
• Revoke Credentials: If a specific verifiable credential or its access was compromised (e.g., a verifier’s system was breached, or you accidentally shared it maliciously), use your wallet to revoke it. If your wallet doesn’t support immediate revocation for that specific credential, contact the issuer to have them revoke it.
• Transfer Assets (if possible): If only your wallet app on a device is compromised, but your seed phrase is still secure and uncompromised, you might be able to recover your identity on a new, clean device. Then, if applicable, quickly transfer any associated digital assets (like cryptocurrencies) from the old DID to a new, secure DID generated from a freshly recovered wallet.
• Notify Issuers/Verifiers: Inform any organizations that issued you VCs, or verifiers you frequently interact with, about the potential compromise. This helps them take preventative action and uphold the integrity of the ecosystem.
• Learn and Adapt: Once the immediate crisis is managed, thoroughly review what happened. Identify the root cause, update your threat model (Step 10), and adjust your security practices to prevent future incidents. Sharing lessons learned (anonymously) can also benefit the wider community.

Code Example (Conceptual Revocation Notification):

# Example notification to an issuer about a compromised credential

{ "event": "credential_compromise", "credential_id": "your-compromised-vc-id", "timestamp": "2025-07-20T10:00:00Z", "details": "Unauthorized access suspected via phishing attack." }

Expected Output:

A clear, actionable plan to follow in the unfortunate event of a decentralized identity compromise, minimizing potential damage and facilitating recovery, allowing you to react strategically rather than impulsively.

Tip: Practice makes perfect. Mentally walk through this incident response plan occasionally so you’re not caught completely off guard if a real event occurs. Knowing what to do ahead of time can make all the difference in mitigating a security incident.

Expected Final Result

By diligently following these steps, you will have established a robust, multi-layered security posture for your decentralized identity. You’ll possess a clear understanding of your DIDs, VCs, and digital wallet, and more importantly, you’ll have implemented practical, actionable safeguards against common and evolving threats. Your decentralized identity will be more resilient, and you’ll be empowered to navigate the digital world with greater confidence and unparalleled control over your personal data. You are no longer just a user; you are a proactive guardian of your digital self.

Troubleshooting Common Issues

• Lost Seed Phrase: Unfortunately, this is often irreversible. If you’ve lost all copies of your seed phrase and your device is compromised or lost, access to your DID and any associated assets may be permanently lost. This underscores the absolute criticality of Step 9. There is no central recovery service for decentralized identities.
• Suspicious Transaction Alerts: If your digital wallet alerts you to an unauthorized transaction, immediately disconnect from the internet, investigate the alert, and follow your incident response plan (Step 11). Do NOT approve any transactions you don’t recognize. Contact your wallet’s official support channels if you need assistance identifying the issue.
• Difficulty Setting Up MFA/Biometrics: Consult your wallet’s official documentation or support channels. Ensure your device’s operating system is updated and supports the required features. Sometimes, app permissions need to be explicitly granted in your device’s settings.
• Phishing Attempts: The best defense is vigilance. Double-check URLs, sender emails, and never click suspicious links. If you accidentally entered your seed phrase or password on a fake site, consider your wallet compromised. Immediately disconnect, then from a secure, clean device, attempt to recover your wallet using your secure, offline seed phrase. If successful, transfer any valuable credentials or assets to a newly generated DID on a fresh wallet, and revoke compromised credentials (if possible).
