fid03 n2gwtl That's strange. It should now work without manual configuration, except that you need to enable Proton Pass in Android settings > Passwords, passkeys & accounts. Could you check that the option in Vanadium settings > Autofill services is set to "Autofill with a different provider"?
fid03 To be clear: you are trying to use passkeys with Proton Pass, and not with a physical security key?
MineralWater Autofill rarely works with Vanadium, whether it's passwords or passkeys. I use the Brave Browser mainly because of this when I know I want to log in on a website and Vanadium only for websites that I can use without an account.
n2gwtl MineralWater passwords and one time passwords generally work very well with proton pass on vanadium for me
fid03 n2gwtl At this point I think basic troubleshooting can be tried. Such as: Navigating to Settings app > Passwords, passkeys & accounts > disabling and then re-enabling Proton Pass, then restarting Vanadium. If there are other accounts enabled in Passwords, passkeys & accounts, you can try disabling those. Checking that GrapheneOS, Vanadium and Proton Pass are all up to date Reinstalling Proton Pass
fid03 n2gwtl it works for vanadium, but not for apps. They still load up Google's passkey system. Odd. I'd first suggest trying points 2 and 3 just to rule out the basics: fid03 Checking that GrapheneOS and Proton Pass are all up to date Reinstalling Proton Pass
