The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to interact with the Ethereum blockchain and Ethereum Virtual Machine (EVM) compatible networks. It serves as both a wallet for storing cryptocurrencies and a gateway to decentralized applications (dApps) on the Web3 ecosystem.
Unlike hardware wallets that store private keys on a physical device, the MetaMask wallet Extension stores encrypted private keys directly in your browser, protected by a password. This provides convenient access to your assets while maintaining security through encryption and secure browsing practices.

To install the MetaMask Extension, follow these steps:
Go to the official MetaMask.com website to ensure you're downloading the genuine extension.
Click the download button and select your browser. The MetaMask Chrome Extension is the most popular, but it's also available for Firefox, Brave, and Edge.
Click "Add to Browser" and confirm the installation when prompted by your browser.
Set up a new wallet or import an existing one using your secret recovery phrase.
Create a strong password and carefully store your secret recovery phrase in a secure location.
The MetaMask login process is designed for both security and convenience:
Click on the MetaMask® icon in your browser's toolbar to open the extension popup.
Type your password to unlock your wallet. This password encrypts your wallet data locally.
Once unlocked, you can view your balances, send transactions, and interact with dApps.
For security, MetaMask® automatically locks after a period of inactivity, requiring your password to unlock again.
To ensure the security of your MetaMask Extension:
Remember that the MetaMask login only requires your password because your encrypted keys are stored locally. Your secret recovery phrase is the ultimate key to your funds.
