Authentication Library

Definitions

1. A reusable library that implements common authentication capabilities such as token validation, session management, OAuth flows, or password hashing. Authentication libraries reduce duplicated security-sensitive code, but they must be integrated carefully to match the product's actual threat model and session behavior.

   In plain English: A library that provides reusable login and authentication features.

   Example: "The team adopted an authentication library for OpenID Connect because maintaining custom token parsing and refresh logic had become too error-prone."
