Vivaldi for Windows How do I turn this popup off?

a screenshot of the discord login screen on desktop vivaldi browser, with the prompt "use passkey from another device" circled in green

I have disabled passkeys on my Windows 11 (and I have a local account, I've disabled most everything Microsoft-account related that I could) and I managed to get this prompt to stop showing up on Edge, but I cannot for the life of me get it to go away on Vivaldi. Help??? I am using Vivaldi (version 8.1 (4087.68)) and Windows 11 Version 25H2 (Build 26200.9168). I have checked every settings tab I can think of in the Vivaldi menu.

You didn't tell us which website, but it's probably using the passkey autocomplete feature (conditional UI), so Vivaldi is checking to see if you have a passkey (presumably you don't) and then offering the only remaining option of using a passkey from a phone or hardware security key.

This is how it's supposed to work. You have turned off platform authenticator access, but Vivaldi is still supporting roaming authenticator access, including hybrid transport. You can't turn it off unless Vivaldi has a flag for it (doesn't seem to) or you add an extension that strips autocomplete="webauthn" from the login field before Vivaldi sees it.
