I guess lucky for me I always enter my password in the Settings app directly, because I don’t know my password and the iPhone won’t let me go to a password manager when it gives me this popup without warning.
Only password outside of my password manager is the Apple one. Exactly because I need it so often that it would be really big issue for me if I have to loose 30 seconds every time I want to enter it.
