What is a single sign-on (SSO)?

Single Sign-On (SSO):

Definition: SSO is an authentication process that allows a user to access multiple applications with one set of login credentials.

Purpose: To streamline the login process, enhance user convenience, and improve security by reducing password fatigue.

How SSO Works:

Process: Users log in once, and a central authentication server authenticates the user across multiple applications.

Examples: Logging into a corporate network and gaining access to email, file servers, and other resources without needing to log in separately for each.

ISO/IEC 27001: Recommends implementing access controls, including SSO, to enhance security and user experience.

NIST SP 800-63: Provides guidelines for digital identity management, including the use of SSO for streamlined authentication.

Cybersecurity References:SSO improves security and user convenience by centralizing authentication and reducing the need for multiple logins.
