MetaMask is one of the most trusted crypto wallet extensions, enabling millions to interact with decentralized applications (dApps), manage digital assets, and securely log in to Web3 platforms. This guide walks through how to install, sign in, and safeguard your wallet on desktop browsers.
Visit the official MetaMask website and select your browser: Chrome, Firefox, Brave, or Edge. Click “Install MetaMask.” Once installed, the fox icon will appear in your browser toolbar.

Your seed phrase is the master key to your assets—store it offline, never share it, and never save it digitally.
After setting your password, you can log in anytime by clicking the MetaMask fox icon. Enter your password and unlock. You can now view your wallet balance, recent activity, and connected networks.
With the MetaMask extension active, visiting a Web3 site (like OpenSea, Uniswap, or Aave) will prompt a connection request. Click “Connect Wallet,” choose MetaMask, and approve via the popup. You’ll remain in full control—transactions require explicit confirmation.
