SSO, or Single Sign-On, is a techinique used to authenticate into a suite of services with the same user credentials. Instead of using an individual authentication system for every service, it uses a single authentication infrastructure to gain access to many services. At its core, SSO allows a client to enter one set of credentials, and have the option to access a number of different applications.
SSO implementations use open standards such as Kerberos and the security affirmation markup language (SAML). SAML is an XML standard that encourages the trading of client verification and approval information across applications and services. SAML-based SSO providers include products such as Okta, Forgerock, Ping Identity, and many others.
Example:
"By deploying passwordless SSO, our workforce was able to save thousands of hours a year that would have been wasted typing in passwords. Now we log into a single portal and instantly gain access to all of our applications and resources."
