MetaMask is a web browser extension and mobile app that allows you to manage your Ethereum private keys. By doing so, it serves as a wallet for Ether and other tokens, and allows you to interact with decentralized applications, or dapps. Unlike some wallets, MetaMask keeps no information on you: not your email address, not your password, and not your Secret Recovery Phrase or other private keys. You retain all power over your crypto-identity.

MetaMask’s extension opens up access between your web browser and decentralized applications (dApps) built on Ethereum or Ethereum Virtual Machine (EVM) compatible networks. Imagine if you were in one country (like the internet) and wanted to visit another country (like the Ethereum blockchain) that speaks a completely different language and has different customs.
