I cannot think of anything on the frontend that needs to be reported about the auth upgrade directly in the userguide. So I added the documentation under solidOS here: https://github.com/solid/solidos/blob/main/documentation/auth-upgrade-to-use-DPoP.md Needs improvements of course.

Screen copy is ok. We need to consider that the login screen is server related.

Ok, for that purpose I link the discussion of how the registration/login has changed as a reference here: https://github.com/solid/solidos/discussions/54 I think this is however UX related and not user guide material. @bourgeoa Is this enough?

I was more thinking of adding a comment saying that the screenshot is from NSS and is server dependant. But may be it not needed

@bourgeoa Do you mean this: https://github.com/solid/userguide/issues/30#issuecomment-1047696638 or another diagram?

Perhaps we need to add an info for the log out, because when you log out from SolidOS that does not mean you log out from your Pod provider, so when you log in again you won't be asked for your password again.

Thank you for the feedback. I have updated the documentation: https://github.com/SolidOS/solidos/blob/main/documentation/auth-upgrade-to-use-DPoP.md
