kertakirjautuminen

Kertakirjautuminen, also known as single sign-on, is an authentication method that allows users to access multiple applications or systems with a single set of credentials. This approach enhances user experience by eliminating the need to remember numerous passwords while maintaining security through centralized authentication mechanisms.

The concept works by establishing a trust relationship between an identity provider and various service providers. Once users authenticate with the identity provider, they can seamlessly access connected applications without repeatedly entering their login information. This is particularly valuable in organizational environments where employees need access to multiple systems throughout their workday.

Kertakirjautuminen is typically implemented using protocols such as SAML, OAuth, or OpenID Connect. These standards ensure secure communication between systems while protecting user credentials. Organizations implementing this solution must carefully manage session timeouts, security protocols, and proper configuration to prevent unauthorized access and maintain data integrity.
