Securing Your Wallet

Backing Up Your Seed Phrase

Backing up your seed phrase is crucial for securing your MetaMask wallet. Here’s how to do it properly:

  • View Seed Phrase:
    • Initial Setup: During the wallet creation process, MetaMask will provide you with a 12-word seed phrase. If you need to view it later, go to “Settings” > “Security & Privacy” > “Reveal Seed Phrase.”
    • Write It Down: Write down the seed phrase on paper. Avoid storing it digitally to reduce the risk of hacking.
  • Secure Storage:
    • Multiple Copies: Create multiple copies of your seed phrase and store them in different secure locations, such as a safe or a safety deposit box.
    • Avoid Sharing: Never share your seed phrase with anyone. No legitimate service will ever ask for it.
  • Test Recovery:
    • Verify Backup: Periodically test the recovery process by using the seed phrase to restore the wallet on a different device. This ensures that your backup is accurate and that you can access your wallet if necessary.

Setting a Strong Password

A strong password adds an extra layer of security to your MetaMask wallet. Here’s how to set and manage a strong password:

  • Creating a Strong Password:
    • Length and Complexity: Use a password that is at least 12 characters long and includes a mix of uppercase and lowercase letters, numbers, and special characters.
    • Avoid Common Phrases: Do not use easily guessable passwords like “password123” or personal information such as your name or birthdate.
  • Managing Passwords:
    • Password Manager: Use a reputable password manager to generate and store complex passwords. This reduces the risk of forgetting passwords and enhances security.
    • Regular Updates: Change your password regularly, especially if you suspect any security breach or unauthorized access.
  • Biometric Security:
    • Enable Biometrics: If your device supports biometric authentication (fingerprint or facial recognition), enable it for added security when accessing the MetaMask app.
    • Two-Factor Authentication (2FA): While MetaMask does not currently support 2FA, enable 2FA on associated accounts (e.g., email, exchanges) to enhance overall security.

  • Periodic Checks:
    • Regular Reviews: Periodically review the list of connected sites and their permissions. Remove any connections that are no longer needed or seem suspicious.
