AuthThe complete toolkit for Web3 Authentication
Easy auth for the most popular web3 wallets and web2 login flows — so you can verify your users’ identities & prove wallet ownership to off-chain systems.
Instant onboarding
Enable any user to verify their identity using web2 sign-in flows such as an email, phone number, or social account — and auto-generate a wallet for them.
Web3-first auth
Build web3 apps with secure, self-custodied, web3-first authentication for your users.
Seamless DX
Powerful SDKs to integrate web3-compatible auth into your app — working with any backend, framework, or service.
Onchain identity verification
Built on the SIWE (Sign-in with Ethereum) standard. Securely verify a user's on-chain identity, without relying on a centralized database to verify their identity.
Comprehensive wallet management
Auth includes a wide range of key management infrastructure for wallets.
Secure token authentication
Secure your backend with a web3-compatible authentication system compliant with the widely used JSON Web Token standard.
What You Can Build
Passwordless auth
Enable users to seamlessly log into any app with just a web3 wallet or web2 login.
Identity verification systems
Securely verify a user's onchain identity & grant them access to gated resources, interaction with your app, and the ability to receive payments with ETH or ERC-20 tokens.
Onchain & offchain data
Understand your users better by merging their web2 and web3 identities — with rich on-chain data.
