What is MetaMask Extension?
MetaMask® is a cryptocurrency wallet and gateway to blockchain applications that operates as a browser extension. It allows users to manage Ethereum-based assets and interact with decentralized applications (dApps) directly from their web browser.
Available for Chrome, Firefox, Brave, and Edge browsers, the MetaMask® extension serves as both a wallet for storing cryptocurrencies and a secure login method for Web3 applications. Unlike exchange-based wallets, MetaMask® gives you full control of your private keys and funds.

Frequently Asked Questions
How do I perform a MetaMask login?
MetaMask® doesn't use a traditional username/password login for security reasons. Instead, you unlock your wallet with the password you set during installation. This password encrypts your wallet data on your device. For added security, never share this password and ensure you've securely stored your secret recovery phrase.
Is the MetaMask Chrome extension different from other browser versions?
The core functionality of MetaMask® is consistent across all browsers. However, the Chrome extension is the most widely used and typically receives updates first. All versions provide the same security features and access to the same networks and dApps.
Can I use MetaMask on mobile and desktop?
Yes, MetaMask® offers both a browser extension for desktop users and a mobile app for iOS and Android devices. You can sync your wallet between devices using your secret recovery phrase, giving you access to your funds and dApps across all platforms.
What should I do if I forget my MetaMask password?
If you forget your password, you can reset MetaMask® using your secret recovery phrase. This will allow you to set a new password while maintaining access to your accounts and funds. Without your recovery phrase, there is no way to recover your wallet.
How secure is the MetaMask wallet extension?
MetaMask® is designed with security as a priority. Your private keys are stored encrypted on your device, not on centralized servers. However, security also depends on user practices: never share your recovery phrase, use strong passwords, verify transactions before signing, and only interact with trusted dApps.
Can I use MetaMask with hardware wallets?
Yes, MetaMask® supports integration with popular hardware wallets like Ledger® and Trezor®. This provides an additional layer of security by keeping your private keys offline while still allowing you to interact with dApps through the MetaMask® interface.
