Hello there,

If you want to learn SSO implementation, AuthO by Okta is best place to start.

We have recently tried logging in using AuthO. Sharing the documentation for the one who needs it.

Note: Try it on Pega's exercise system, as AuthO will need your system to be on cloud in order to have a connection. If you are using localhost, then you can use ngrok  to expose your localhost to internet.

Thank you and stay safe, Siddhant Suryakant Jivane
