AuthModule

AuthModule is a conceptual or actual software module designed to handle authentication and authorization within an application. Its primary responsibility is to verify the identity of users attempting to access a system and to determine what actions they are permitted to perform. The module typically integrates with various identity providers, such as username/password databases, OAuth services, or single sign-on (SSO) solutions.

When a user attempts to log in, AuthModule receives their credentials and validates them against stored information. Upon successful authentication, it may generate a session token or a JSON Web Token (JWT) that is subsequently used to authorize subsequent requests. Authorization, often managed by AuthModule or a related component, involves checking the user's roles and permissions against the requested resource or action.

The implementation of AuthModule can vary significantly depending on the technology stack and architectural patterns employed. It might be a standalone service, a library integrated into the application's backend, or a part of a larger identity and access management (IAM) system. Key features often include user registration, password management, session management, token issuance and validation, and role-based access control (RBAC). Security is paramount, and AuthModule implementations must adhere to best practices to prevent common vulnerabilities like brute-force attacks and credential stuffing.
