SSO was created for IT managers who found remembering IDs and passwords for hundreds of IT services, servers, and corporate applications to be difficult. They may use a single password and user ID to access various services on the corporate network thanks to SSO. In recent years, SSO has made its way to the web for consumers. If you log into Gmail, for example, you may open other Google services (in other browser tabs) without having to log in again. Gmail credentials may be used for Google Drive, Google Maps, Google Photos, and other Google services. As a result, SSO solutions are extremely useful since they eliminate the need for end-users to remember numerous passwords.
