User experience upon registration/login

[timea-solid]

I noticed an interesting user experience on the registration/login and I also noticed some mentions about pages from the server and from SolidOS. To try to understand better what is going on I created a diagram: https://drive.google.com/file/d/1DlKyTinKbvZaFB6qu5KdbSfG4ggB8HeQ/view?usp=sharing

I have some questions about this:

• did I get the diagram right?
• which pages are served from the server (NSS in this case) and which from SolidOS Databrowser?
• is there a reason why one needs to sign in twice if coming from registration? Is it because of the ID provider?
• which is the 1st page the user should see? (there seems to be 2).
• how do I get to the data folder list view when I am logged in?
  P.s. Will it all change with the new auth?

(The diagrams for some reason are very big but very low resolution in Chrome, but downloaded, the PNG is legible on a laptop.)
I am disinclined to go into this flow in detail, as the flow may have changed in the upgraded auth version.

After the Auth upgrade work the user flow looks like this:
