Yksittäiskirjautuminen
Yksittäiskirjautuminen, commonly known by its English abbreviation SSO (Single Sign-On), is an authentication scheme that allows a user to log in with a single set of credentials to gain access to multiple independent software systems. Instead of requiring separate usernames and passwords for each application, SSO centralizes the authentication process. When a user successfully authenticates with an SSO system, they are granted access to all connected applications without needing to re-enter their credentials for each one.
The primary benefit of SSO is enhanced user experience. It reduces the number of passwords users need
SSO solutions typically rely on protocols like SAML (Security Assertion Markup Language), OAuth, or OpenID Connect.
