A method where the service provider (SP) initiates the single sign-on process to authenticate users.
Description
Service Provider Initiated SSO is a single sign-on (SSO) process where the service provider, rather than the identity provider (IdP), initiates the authentication sequence. This means that when a user attempts to access a service or application, the service provider redirects the user to the identity provider for authentication. After successful authentication, the user is redirected back to the service provider with an authentication token. This approach is commonly used in various online applications and platforms, enabling users to log in seamlessly without needing to enter credentials multiple times. For example, when a user tries to access their Google Drive, Google acts as the service provider and redirects the user to their Google account for login verification. Once authenticated, they can access their files without needing to log in again. This method enhances user experience and security by minimizing password fatigue and reducing the number of times users need to enter their login information.
Examples
- Google Workspace allows users to access multiple applications, like Gmail and Google Drive, through Service Provider Initiated SSO.
- Salesforce uses Service Provider Initiated SSO for users to log in to various services after authenticating through their corporate identity provider.
Additional Information
- Service Provider Initiated SSO is often used in enterprise environments where multiple applications require authentication.
- This method improves security by centralizing user authentication and reducing the risk of password theft.
