Authgear is an identity and authentication platform for consumer and B2B applications, providing hosted login, user management, and standards-based SSO. It can be deployed for self-hosting and is designed to support modern authentication methods across web and mobile.
Key Features
- Pre-built, customizable signup/login and account settings UI
- Passwordless authentication (magic link / OTP via email and SMS) and passkeys (WebAuthn)
- Multi-factor authentication (TOTP, email OTP, SMS OTP)
- SSO and federated identity via OAuth 2.0 / OIDC and SAML 2.0
- Admin portal for configuration, user/session management, and operational insights (e.g., logs)
- Admin API with GraphQL for managing auth resources and automation
- Extensibility via webhooks and server-side hooks for custom auth logic
- Enterprise-oriented controls such as audit logs, rate limiting, and brute-force protection
Use Cases
- Add authentication to SaaS products and multi-app ecosystems with a unified identity layer
- Implement enterprise SSO for B2B customers using OIDC/SAML and directory integrations
- Roll out phishing-resistant sign-in using passkeys plus MFA for higher assurance logins
Authgear combines turnkey UI components with protocol support and administrative tooling, making it suitable for teams that want a customizable IAM foundation without building auth from scratch. Its API and hooks enable deeper integration while keeping authentication flows consistent across platforms.
