Hi, thanks for your reply. Now I'm feeling a bit silly. On a closer look, it's not actually the password manager, it's the "secure keyboard input". Which makes sense, as from what I could see in my settings, the password manager has not been set up.
The pop up disappears in a few seconds, which I didn't realize before, as I enter my log in and pw very quickly.
So, I guess i just leave it, ignore it, it's a good thing ?
As I said, I do feel a bit silly ? Thanks for your time.
