What Firebase Auth is
Firebase Auth is a service that authenticates users in apps. It is for app teams that need to identify users and manage sign-in.
It provides backend services, SDKs and UI libraries for authentication. Apps can support passwords, phone numbers and federated identity providers, and connect authentication with other Firebase services using OAuth 2.0 and OpenID Connect. An optional Identity Platform upgrade adds multi-factor authentication, logging, SAML, OpenID Connect and multi-tenancy.
