Designed to simplify and secure the interaction between users and the Ethereum blockchain. It serves as a bridge that connects users to decentralized applications (dApps), allowing them to access various blockchain services and manage their cryptocurrency holdings with ease.
When users first install the Metamask extension in their preferred web browser (e.g., Chrome, Firefox, or Brave), they are prompted to create a new wallet or import an existing one using a 12-word seed phrase. This seed phrase acts as the master key to the wallet and should be stored securely, as it grants access to the user's funds. After setting up the wallet, users are required to create a strong password to enhance security.
