SSO means: “I trust «other\_site» to rely on ALL of my authentication and rely on it exclusively for this purpose.” That other site could be anything - it could be your Corporate SSO site, it could be [something horrible that trusts users completely](https://meta.discourse.org/t/bratwurst-the-wurst-possible-production-sso-provider/72343), it could be a provider that requires an RSA key with certificates, heck it could even be [(another) Discourse](https://meta.discourse.org/t/using-discourse-as-a-sso-provider/32974). oauth2 means: “This is a login option for my site” such as Google oauth2.
