MetaMask Login

Secure Web3 Authentication for Decentralized Applications

What is MetaMask?

MetaMask is a cryptocurrency wallet and gateway to blockchain applications. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then interact with decentralized applications (dApps).

With over 30 million users worldwide, MetaMask provides a key vault, secure login, and token wallet—everything you need to manage your digital assets.

How MetaMask Login Works

MetaMask login provides a secure alternative to traditional username/password authentication. Instead of creating accounts on each website, users authenticate using their Ethereum wallet.

1
A dApp requests authentication from the user's MetaMask wallet
2
MetaMask prompts the user to sign a unique message with their private key
3
The dApp verifies the signature to authenticate the user
4
The user gains access without sharing sensitive information
