Auth0

Auth0 is a platform for authentication and authorization. It provides a Universal Login page that handles the complexity of authentication protocols (SAML, OIDC, OAuth) and identity providers (Google, Enterprise, Database).

When to Use

• Enterprise Universal Login: Outsourcing authentication, MFA, and social/enterprise federated logins to managed Auth0 infrastructure.
• B2B Multi-Tenant Identity: Managing distinct organizational customer portals with custom domains, SAML/WS-Fed, and SCIM provisioning.
• Fine-Grained Role-Based Access Control: Defining custom roles, permissions, and claims enforced across APIs and frontends.
• Machine-to-Machine (M2M) Authorization: Securing daemon background services using OAuth 2.0 Client Credentials grants.
