What is Authentication?
Firebase Authentication provides backend services for authenticating users with email and password, phone numbers, or federated identity providers like Google, Facebook, and Apple. It manages tokens and session state securely. On Android, it integrates with the Firebase SDK to handle sign-in flows with minimal boilerplate.
