Two-tier credentials

Hi guys,

I desperately tried to look this up in the knowledge base before writing in the forum, but my problem is, that I do not even know what this is called what I am looking for.

So, I would like to simply add a website session to the navigation, but this site has first a drop-down, to select where would I like to authenticate myself:

So I am already managing with stored credentials for websites, that directly lands with the e.g. username and password field. This information is stored in the session settings, however, for this "two-tiered" authentication it doesn't pull the information from the session.

When I select the desired domain, and click on next, the username and password fields aren't filled out automatically, despite the field ID being correct in the session settings.

Is there a way to configure a session with stored credentials, in a way:

IF

xxx domain is selected (on the first page)

THEN

use <these credentials> (on the next page)

Any advice would be much appreciated.

Thank you guys!

Cheers,

Csaba
