Install & Setup MetaMask
MetaMask is a popular Ethereum-based wallet available as a browser extension for Chrome, Firefox, Brave, Edge and as a mobile app on iOS and Android.
To start, visit the official MetaMask website and download the browser extension or mobile app.
Create a New Wallet
After installation, open MetaMask and choose Create a Wallet. Agree or opt-out of data usage preferences and set a strong password.
You will receive a secure 12-word Secret Recovery Phrase (seed phrase). Write it down offline and store it safely. This phrase restores your wallet if you lose access. Do not share it digitally.
Import Wallet
If you already have an Ethereum-compatible wallet, choose Import Wallet and enter your recovery phrase or private key to restore access.
Login Process
Login to MetaMask is straightforward using your password or biometric authentication on mobile devices.
Open your MetaMask extension or app, enter your password and access your wallet dashboard to manage assets.
If you forget your password, you can restore your wallet using your Secret Recovery Phrase on reinstall.
Security Best Practices
MetaMask secures funds by storing private keys encrypted locally. Here are key tips to maximize security:
- Never share your Secret Recovery Phrase or private key.
- Always install MetaMask from official sources to avoid phishing scams.
- Use hardware wallets like Ledger or Trezor for better security linked to MetaMask.
- Enable biometric or strong passwords on mobile devices.
- Beware of suspicious links or dapps requesting secret data.
Developer Access & Integration
MetaMask offers developers a secure way to authenticate users via wallet signatures in dapps and smart contracts.
Using Ethereum's Web3 API and MetaMask’s provider, developers can request users to sign messages, transactions, and manage their wallets securely on the blockchain.
This cryptographic login replaces traditional password flows—users prove ownership of wallet addresses, enabling seamless authentication and interaction.
Developers use MetaMask's API to enable functionalities such as token swaps, NFT minting, DeFi interactions, and secure on-chain transactions.
