I have passkeys stored in Bitwarden for multiple sites.
But when I try to access those web sites from my windows 10 PC with edge, edge/windows “steals” the passkey prompt from Bitwarden (see screenshot). If I hit cancel on that dialog, the entire passkey flow is aborted.
I saw some other threads that mentioned the exclusion list in bitwarden - mine is empty.
Have checked settings on Edge, Windows, and Bitwarden
Did this ever work for you in Windows 10 with Edge?
Also, what version of the Bitwarden browser extension is installed on your Edge browser? If you go to Settings > Notifications, have you enabled the option “Ask to save and use passkeys” (as shown in the screenshot below)?
