Troubleshooting MetaMask Login: Solving Common Login Headaches

Login issues happen—even to seasoned users. This guide tackles the most common glitches and how to overcome them efficiently.

✅ Problem 1: “Wrong Password” Error

  • Confirm Caps Lock isn’t on.
  • Make sure you're using your original MetaMask extension—not a copy under a new browser profile.
  • If password fails repeatedly, restore using the seed phrase:
  1. Click “Import Wallet” on login screen
  2. Enter 12‑word phrase → set new password
  • Still failing? Check if you’re using the correct seed phrase—some extensions hold multiple accounts.

🔄 Problem 2: Extension “Crashes” or Doesn’t Open

  • Clear browser cache/cookies.
  • Go to chrome://extensions (or equivalent), disable/enable MetaMask.
  • Check browser version—MetaMask works best on latest stable browsers.
  • If still broken: uninstall, reinstall extension, then import wallet again.

🌐 Problem 3: dApp Connection Fails on Login

  • You might be on wrong network (e.g., testnet vs mainnet).
  • Switch networks in MetaMask dropdown.
  • Disconnect shady sites: Settings → Advanced → Clear Approved Sites.
  • Fully close and revisit the dApp fresh.

🔄 Problem 4: Seed Phrase Doesn’t Restore

  • Confirm correct word order and spelling.
  • Ensure no leading/trailing spaces.
  • Test phrase on an offline seed-checker (no internet).
  • If wallet had multiple accounts, only the first will appear. You may need to click “Create Account” to generate others – same address sequence from seed.

👻 Problem 5: “Account Not Found” or Empty Balance

  • Confirm you're on the right network.
  • Check Etherscan or blockchain explorer to verify transactions for your address.
  • If balance shows on explorer but not in MetaMask:
  • Click “Import Tokens” using measured contract address.
  • If nothing shows up in explorer—your seed/address might be mistyped.

🔒 Problem 6: Security or Phishing Warnings

  • Use a site like etherscamdb.info to check domain reputation.
  • If login prompt seems off, don’t proceed—force close browser and clear cache.
  • Reinstall MetaMask from official source, change password, reimport seed.

🛠 Advanced Debugging Tips

  • Open browser console (F12) → check MetaMask error logs.
  • See network requests under "Network" tab to catch RPC errors.
  • Enable developer mode in MetaMask Settings → show experimental logs.
  • Post specific issues to MetaMask support or GitHub—and share console logs.
