One wallet connector for every auth method
Email magic links, OAuth, passkeys, or external wallets — one wallet connector handles them all. Openfort creates a non-custodial wallet per user behind the scenes without seed phrases.
Wallet authentication without vendor lock-in
Self-host key management with OpenSigner, migrate auth providers later without changing wallet addresses. Your wallet authentication, your rules.

Frequently Asked Questions
Can't find your answer?
Openfort wallet authentication works with your existing auth stack — email magic links, OAuth, social logins, passkeys, or external wallet connectors. When a user authenticates, your system issues a trusted identity (JWT or OIDC token). Openfort uses that identity to deterministically create or retrieve a non-custodial wallet for that user, without seed phrases. To the user, it feels like a normal sign-in.
A wallet connector bridges your app to a user's wallet. Openfort acts as a universal wallet connector that supports social logins (Google, Apple), passkeys, email magic links, and traditional external wallets like MetaMask or WalletConnect. Unlike standalone wallet connectors, Openfort also creates and manages non-custodial smart wallets behind the scenes, so every user gets a wallet regardless of how they authenticate.
Yes. Openfort is designed to sit behind your auth, not replace it. You keep your OAuth, SSO, or passkey flow, and once a user is authenticated, Openfort links that identity to a non-custodial smart wallet. You get passwordless wallet authentication UX while keeping full control over wallet policies and infrastructure.
Most wallet connectors only handle connecting to existing wallets. Openfort goes further: it combines wallet authentication with embedded wallet creation, gas sponsorship, session keys, and account abstraction — all in one SDK. You can start with hosted key infrastructure and later self-host with OpenSigner, without forcing users to migrate wallet addresses.
Openfort ships TypeScript/JS SDKs and React helpers that integrate with Next.js, React, and other frameworks. It also supports Firebase Auth, custom JWTs, Telegram Mini App initData, and Unity. The wallet connector works with whatever auth provider you already use — Openfort handles wallet creation, orchestration, and signing.
