Firebase Authentication is Google Firebase's user authentication service. It lets you add email/password, phone number, social login such as Google, Apple, and Facebook, and anonymous login to an app with a few lines of SDK code, and it issues ID tokens to authenticated users that are used for access control in other Firebase services such as Firestore. It is compared with self-hosted Keycloak and with managed authentication services such as Auth0 and AWS Cognito.
