What is MetaMask® Extension?
MetaMask® is a cryptocurrency wallet and gateway to blockchain applications that operates as a browser extension. It allows users to manage Ethereum-based assets and interact with decentralized applications (dApps) directly from their web browser.
The MetaMask® Extension serves as a bridge between your browser and the Ethereum blockchain, enabling you to run Ethereum dApps right in your browser without running a full Ethereum node.
Download and Installation
The official MetaMask® Extension can be downloaded from the Chrome Web Store, Firefox Add-ons store, or directly from the official MetaMask® website. Always ensure you're downloading from official sources to avoid phishing attempts.
After adding the extension to your browser, you'll need to either create a new wallet or import an existing one using your secret recovery phrase.
MetaMask® Login Process
Unlike traditional accounts, MetaMask® doesn't use a username/password system for access. Instead, your wallet is protected by:
- A password that encrypts your wallet on your device
- A secret recovery phrase (12 or 24 words) that controls access to your funds
To "login" to MetaMask®, you simply enter your password to unlock the extension on your browser. If you switch devices or browsers, you'll need your secret recovery phrase to restore your wallet.
Security Warning: Never share your secret recovery phrase with anyone. MetaMask® support will never ask for this phrase.
