Introduction
MetaMask is a leading Ethereum wallet and browser extension for accessing blockchain apps (dApps). Your wallet is the gateway to digital assets like ETH, tokens, NFTs, and DeFi platforms. Secure login is essential to protect your funds. This guide provides detailed instructions for logging in, enabling security measures, recovering access, and following best practices for digital asset management.
1. How to sign in
To log in, open the official MetaMask extension or mobile app. You can also visit the official website metamask.io and follow links to download or sign in. Enter your password and unlock your wallet. For first-time users, set up a secure password and safely store the recovery seed phrase provided during installation.
Always verify you are using the official MetaMask site or app. Never share your seed phrase — it provides full access to your wallet.
2. First-time login & wallet setup
During first-time login, you will create a wallet password and receive a 12-word seed phrase. Write it down securely and never store it digitally. Confirm the seed phrase to complete setup. This ensures you can recover your wallet on a new device or in case of lost access.
3. Enabling additional security
MetaMask supports password protection and device-based biometric unlock. Use strong passwords and consider enabling app-level biometrics if supported. For browser extensions, secure your computer with OS-level passwords and antivirus protection.
4. Passwords and recovery phrases
Never reuse passwords. Store your recovery seed phrase offline in a safe location. If you forget your password, use your recovery phrase to restore the wallet. Losing both password and seed phrase results in permanent loss of funds.
5. Common login issues & fixes
- Check that your password is correct and caps lock is off.
- Ensure your browser extension or app is up to date.
- For seed phrase restoration, ensure words are in correct order.
- Clear browser cache if extension malfunctions.
- Contact official MetaMask support if issues persist: MetaMask Support.
6. Session management & device safety
Log out when using public devices. Protect your devices with OS-level passwords or biometrics. Review connected sites and revoke permissions regularly in MetaMask settings.
7. Security best practices
- Use a strong password for your wallet.
- Never share seed phrases or private keys.
- Enable device-level security (biometrics or password).
- Only connect to trusted dApps and websites.
- Keep your apps and browser updated.
8. Using MetaMask for DeFi and assets
Once logged in, you can interact with DeFi apps, swap tokens, and manage NFTs. Always verify addresses before sending funds and check gas fees on Ethereum transactions.
9. MetaMask Mobile App
The MetaMask mobile app provides full wallet functionality with added security like biometrics. Download only from official sources: MetaMask Downloads.
10. If your wallet is compromised
Immediately revoke access to connected sites and transfer funds to a new wallet if necessary. Contact official support and never share recovery phrases with anyone claiming to help.
