MetaMask Overview
MetaMask is a popular Ethereum and blockchain wallet primarily functioning as a browser extension or mobile app. It enables secure management of your crypto, decentralized apps (dApps) interactions, and private key control locally on your device.
Unlike traditional apps, MetaMask stores your keys encrypted on your device, ensuring you alone have access. It connects you securely to the Ethereum blockchain and compatible networks seamlessly.
Secret Recovery Phrase & Wallet Security
When you create a MetaMask wallet, you receive a Secret Recovery Phrase (seed phrase) — a unique set of 12 or 24 words that provide access to all your blockchain accounts.
- This seed phrase is the master key; keep it offline and never share it.
- MetaMask cannot recover your wallet without it.
- You can import multiple accounts derived from the seed phrase.
- Backing up your seed phrase securely protects you if your device is lost or damaged.
Login & Password Management
MetaMask uses a local password to secure access to the wallet interface on your device.
- The password encrypts your data locally.
- MetaMask cannot reset or recover this password for you.
- Use strong, unique passwords and consider biometric unlock where available.
Phishing Awareness & Best Practices
Phishing attacks attempt to trick you into revealing your seed phrase or private keys.
- Never enter your seed phrase on websites or share it with anyone.
- Check URLs carefully before interacting with wallets or exchanges.
- MetaMask and official support will never ask for your seed phrase.
- Use hardware wallets in tandem with MetaMask for enhanced security.
Two-Factor Authentication & Additional Security
While MetaMask does not have built-in 2FA, securing the device or browser environment separately is essential.
- Use 2FA on associated exchange accounts or platforms that interact with MetaMask.
- Consider device-level security, such as biometrics or screen locks.
- Regularly update your MetaMask and browser to include the latest security patches.
