What is Single Sign-On (SSO)?
It is the use of a single credential (eg: username and password) to log into several applications without prompting the user to log in multiple times. SSO can be implemented via open standards like OpenID connect, Security Assertion Markup language (SAML), WS-Federation, etc. Managing and federating users is an enormous task; however, a business should spend time focusing on increasing productivity and efficiency as well as the end-user experience, which is what SSO helps to do. A good SSO solution will help developers set it up with minimum code changes, and simple integrations with applications.
