Authgear is an open-source customer identity and access management (CIAM) platform serving as a self-hostable alternative to Auth0, Clerk, and Firebase Auth. It provides pre-built login and account settings pages, passkeys, passwordless OTP/magic links, biometric login, MFA, SSO via OIDC/OAuth 2.0/SAML, RBAC, and attack protection features like bot detection and rate limiting.
Use cases
- self-host an auth0 alternative for my saas app
- add passkey and passwordless login to a mobile app
- implement sso with oidc for multiple web apps
- add mfa and 2fa to user sign-in
- replace firebase auth with a self-hosted identity provider
- add social login with google apple and github
- protect login flows from bots and brute-force attacks
- manage user roles and rbac for a b2b saas
When to choose
- you need consumer-facing authentication (CIAM) with pre-built, brandable login UI
- you want modern login methods like passkeys, biometrics, and WhatsApp/SMS OTP out of the box
- you need an open-source, self-hostable alternative to Auth0, Clerk, or Firebase Auth
- you need enterprise protocols like OIDC, OAuth 2.0, SAML, LDAP, or ADFS federation
- you want built-in attack protection: bot detection, rate limits, breached password checks, SMS pumping defense
When to avoid
- you only need simple internal workforce SSO with no consumer identity features
- you want a lightweight embeddable auth library rather than a full identity server to operate
- your stack requires a solution in a language other than Go or without a hosted option
- you need deep customization beyond the portal, admin API, hooks, and custom auth flows
