MetaMask Security Tips

  • Backup Your Seed Phrase: Your 12-word recovery phrase is the only way to recover your wallet if something happens to your device. Keep it secure and never share it with anyone.
  • Use Strong Passwords: Create a strong password for your MetaMask wallet, and don’t share it with anyone.
  • Avoid Phishing Scams: Be cautious of phishing attempts, and always double-check the URL of the MetaMask site and dApps you interact with.
  • Enable Two-Factor Authentication (2FA): Although MetaMask doesn’t support 2FA natively, you can use external services or hardware wallets for additional security.
