MetaMask Login — secure access to your Ethereum wallet and Web3 applications. This page explains official MetaMask Login procedures, security considerations, recovery options, and developer integration in a concise, no-boiler format.
MetaMask Login is the process by which a user unlocks their MetaMask wallet (extension or mobile app) to access accounts and sign transactions. A MetaMask Login requires either the account password for a locally stored vault or restoring the wallet using a Secret Recovery Phrase when migrating or reinstalling. Follow official MetaMask Login guidance to protect keys and avoid phishing.
To perform your first MetaMask Login, install the official MetaMask browser extension (Chrome, Firefox, Edge) or the official mobile app from trusted app stores. During initial setup you will create a password and receive a Secret Recovery Phrase — store that phrase offline and never share it. Use the secure password to complete your first MetaMask Login on the device where you installed the extension or app.
Treat MetaMask Login credentials and the Secret Recovery Phrase as the highest-sensitivity secrets. Do not enter your Secret Recovery Phrase on websites or in chats. Use a strong password for each device and ensure the device is free from malware before performing any MetaMask Login. When requested to sign a message or transaction after a MetaMask Login, verify the originating dApp URL and intent.
If you manage multiple accounts, keep a documented, offline mapping of which account addresses correspond to which purpose — but never store the Secret Recovery Phrase in cloud storage or email.
To restore access when you have reinstalled MetaMask or changed devices, use the Secret Recovery Phrase via the "Import using Secret Recovery Phrase" flow. Enter each recovery word exactly (lowercase) in the sequence provided when the wallet was created. Restoring the wallet will allow you to complete the MetaMask Login and recover associated accounts and balances.
Common MetaMask Login issues include forgotten passwords (recover with Secret Recovery Phrase), incorrect network selection, and browser conflicts with other wallet extensions. If you lose your password but still have the Secret Recovery Phrase, restore the wallet and set a new password. For unresolved issues, consult MetaMask Support or the Help Center.
If your dApp requires MetaMask Login, integrate via the MetaMask extension API or the MetaMask SDK to request account connection and signatures. Use standard patterns (e.g., `ethereum.request({ method: 'eth_requestAccounts' })`) to trigger a MetaMask Login/connection prompt. Always request only the permissions you need and provide clear UX around signing actions.
