What is Auth0?

Identity platform with authentication, authorization, and user management for web, mobile, and API applications. Free up to 25,000 MAUs, paid plans from $35/month.

Auth0 is the authentication layer you bolt on so you never have to think about password hashing, token rotation, or SAML integration again.

Building authentication from scratch takes a security-focused team 3-6 months to get right. One mistake in session management or password storage creates a breach. Auth0 replaces that risk with a single integration that handles login flows, MFA, SSO, and user management across every identity protocol your enterprise customers will demand (SAML, OAuth 2.0, OpenID Connect, WS-Federation).
