About Auth0
Auth0 is designed to handle the most complex identity scenarios, including enterprise federation (SAML/OIDC), specialized security requirements, and massive user bases. It provides a highly extensible 'Actions' framework where you can write custom code to run during the auth flow. While it offers pre-built login pages, it is mostly used via its powerful API. It's the standard choice for large companies that need a reliable, compliant, and battle-tested identity solution.
