A secure and decentralized way to authenticate with Web3 applications using your Ethereum wallet
MetaMask Login is a secure authentication method that allows users to access decentralized applications (dApps) using their Ethereum wallet instead of traditional usernames and passwords.
This approach eliminates the need for centralized user databases and gives users full control over their digital identity.
When you visit a dApp that supports MetaMask login, the application will request a signature from your wallet to verify your identity.
This process doesn't expose your private keys but creates a cryptographic proof that you control the wallet address.
MetaMask login provides enhanced security by eliminating password-related vulnerabilities like phishing, database breaches, and password reuse.
Your identity is secured by your private keys, which never leave your device and are protected by your MetaMask password.
MetaMask login provides a seamless, secure, and user-controlled authentication experience that aligns with Web3 principles of decentralization and self-sovereign identity.
DApps send a unique message for you to sign with your wallet, creating a verifiable proof of ownership.
Your private keys remain secure in your wallet. Only cryptographic signatures are shared with applications.
Applications can maintain authenticated sessions without storing sensitive user credentials.
Your MetaMask identity works across all compatible dApps without creating new accounts.
The dApp detects MetaMask and requests to connect to your wallet.
You choose which Ethereum account to use for authentication.
You review and confirm the signature request in MetaMask.
The dApp verifies your signature and grants access to your account.
