What is serveurs d'authentification?

Serveurs d'authentification (Authentication Servers) are a critical component of modern computer systems, networks, and applications. They are responsible for verifying the identity of users or devices attempting to access protected resources. This involves confirming that the credentials presented (such as usernames and passwords, biometrics, or digital certificates) match a stored record. Successful authentication grants access based on pre-defined roles and permissions, while failed authentication denies access. Authentication servers are widely used in web applications, operating systems, network security, and cloud computing to ensure secure and controlled access to sensitive information and services.
