Login Essentials
How does MetaMask protect my login credentials?
MetaMask uses local encryption to store your private keys directly on your device. Your vault is protected by a password that decrypts it locally; no sensitive data or recovery phrases are ever transmitted to or stored on MetaMask servers.
Do I need to pay gas fees just to log in to a site?
No, logging in or 'signing' a message to authenticate your identity does not require gas fees. Gas is only consumed during on-chain transactions, such as transferring assets or interacting with smart contracts.
How do I sync my desktop wallet with the mobile app?
To sync devices, you must manually import your wallet using your 12-word Secret Recovery Phrase on the mobile app. For maximum security, MetaMask has deprecated automated QR syncing to prevent remote hijacking attempts.
What if I forget my password but have my seed phrase?
If you lose your login password, you can restore access by clicking 'Forgot Password' and entering your Secret Recovery Phrase. This allows you to set a new password and regain access to your decentralized funds.
Is the MetaMask extension safe on shared computers?
We strongly advise against using MetaMask on public or shared devices. Malicious scripts or keyloggers could compromise your extension. Always use a personal, secure device and consider a hardware wallet for added protection.
