Single Sign-On (SSO)
A login system letting users authenticate once to access multiple applications, instead of separate passwords for each.
SSO centralizes authentication through one identity provider, which improves both security (one strong login to protect and monitor, instead of dozens of weak ones) and user experience. It also makes offboarding faster and more reliable: disabling one central account cuts access to every connected application at once, rather than hunting down access across many separate systems.
