How does SSO work? (self.explainlikeimfive)

Also why is it sometimes called a federated ID? Does it have to be an email address or could any value work?

A lot of different possible answers.

SSO is the concept, “single sign on” one set of credentials that you can use in multiple places.

Federated id’s are passed in the back end, as opposed to OIDC which works based on “pass back tokens”

Emails are usually used because they make great usernames. They’re definitely unique and people remember them, but it doesn’t have to be emails.
