Metamask Extension: How to Set Up, Add Networks

How MetaMask Login Works

MetaMask doesn’t use a traditional “login” system like centralized exchanges. Instead, you unlock your wallet using a password that decrypts the private key stored on your device. You must have installed the MetaMask extension or mobile app beforehand.

How to Log In (Unlock) MetaMask

Open MetaMask: Click the MetaMask fox icon in your browser toolbar or open the mobile app.
Enter your password: Type the password you created during wallet setup.
Click “Unlock”: Your wallet will open, showing your account address and balance.
Start using Web3: You can now connect to dApps, send crypto, or manage tokens.

MetaMask support will never ask for your seed phrase or private keys. Never share them.

If You Forgot Your Password

You cannot recover your password through MetaMask. To reset it:

Click Reset Wallet on the login screen.
Enter your 12‑word Secret Recovery Phrase.
Create a new password.

Your seed phrase is the only backup. If you lose it, your wallet cannot be recovered.

Common Login Issues & Solutions

MetaMask not opening: Restart your browser or reinstall the extension.
Wrong password: Reset the wallet using your seed phrase.
Blank screen: Clear cache or disable conflicting browser extensions.
Extension missing: Reinstall MetaMask from official sources only.

Security Tips for Safe Login

Use a strong, unique password.
Store your seed phrase offline in a secure location.
Do not enter your seed phrase anywhere except MetaMask during wallet recovery.
Verify URLs of all dApps before connecting your wallet.
Consider using a hardware wallet (Ledger/Trezor) with MetaMask for extra security.
