Single Sign-On is a protocol (securely) transferring the authentication conducted with one website to another website, seamlessly, so the user does not need multiple passwords. It enables seamless interconnection between different domains.
For decades, Single Sign-On was the 'holy grail' of application software, that everyone desired to have implemented.
Sometime around the mid to late 1990s there were many implementations.
It enables interconnection and collaboration between different software suites that may have been designed and operated by entirely different organizations at different times.
A flaw in Single Sign-on could expose a lot of goodies.
