What is MetaMask?

MetaMask is a browser extension and mobile app that lets you store, manage, and interact with cryptocurrencies like Ethereum and thousands of ERC-20 tokens. It also serves as a gateway to the world of decentralized finance, NFT marketplaces, Web3 games, and blockchain applications.

Unlike traditional accounts, MetaMask does not use typical usernames or passwords. Instead, it provides a Secret Recovery Phrase and a private key that gives you full control of your wallet. This makes security extremely important.
