SSOjärjestelmään

SSOjärjestelmään, or Single Sign-On system, is a method of authentication that allows a user to log in with a single set of credentials to gain access to multiple independent software systems. Instead of managing separate usernames and passwords for each application, users only need to remember one. This streamlines the user experience and reduces the burden of password management.

When a user attempts to access a protected application within an SSO system, they are typically redirected to a central authentication service. This service verifies the user's identity, often through username and password, multi-factor authentication, or other secure methods. Once authenticated, the central service issues a security token or assertion. This token is then passed to the requested application, which trusts the authentication service and grants the user access without requiring another login.

The benefits of SSOjärjestelmään include enhanced user convenience, improved security through centralized management and reduced password reuse, and increased productivity by minimizing login time. It is widely adopted by organizations to manage access to internal applications, cloud services, and other digital resources. The implementation of an SSOjärjestelmään typically involves an identity provider (IdP) that handles authentication and service providers (SPs) that rely on the IdP for user verification.
