Single Sign-On (SSO)
Single Sign-On (SSO) is an authentication method that enables users to access multiple applications or services with a single set of credentials (username and password).
Instead of having to log in to each individual service separately, SSO provides a centralized authentication mechanism, which verifies the user’s identity once and then grants access to all authorized services and applications.
SSO can be achieved through various technologies and protocols, such as:
- SAML (Security Assertion Markup Language)
- Kerberos
- OAuth/OIDC (Open Authorization/OpenID Connect)
- LDAP (Lightweight Directory Access Protocol)
Advantages of SSO include increased productivity and convenience for users, improved security by reducing the number of passwords to manage, and reduced costs for organizations through reduced helpdesk support and improved password management.
