Authentication Service

Definitions

1. A dedicated service that handles login, credential validation, token issuance, session management, or identity federation for one or more applications. Centralizing authentication in a service can simplify integration, but it also creates a critical dependency that must be highly reliable and well-observed.

   In plain English: A service that performs login and identity-related functions for applications.

   Example: "The platform extracted auth into a standalone authentication service so each product did not need to implement password resets and token rotation differently."
