Here’s a rare issue which may help someone else. I don’t come across this often, but if a newbie wonders what to do, here ya go.
I was signing up with my dental insurance website. Turns out they have separate addresses from the main page and the member sign-in page. The sign in page creates a different session extension every time.
Ex: (main site) htt://www(dot)DentalInsCo(dot)com/
(sign-in) htt://pro(dot)dental.auth0(dot)com/login?state=hKFo2SBua1ZpV…
htt://pro(dot)dental.auth0(dot)com/login?state=hKFo2SBGaDl
Therefore, Bitwarden could not identify the site to display the auto-fill info. Experienced users may know this already, but new users who are wondering, simply save the first part (htt://pro(dot)dental.auth0(dot)com) on the second line of the website url field and you’re good to go.
Hope this helps someone out there. Have a great day.
