Upstate1618 It seems you register a non-passkey for Proton on Proton Pass on your PC and authenticate it on your PP using Vanadium on GOS. This is impossible. Can you be sure and give more details?
It's not impossible. I simply did this:
- Open up Brave on Windows with the Proton Pass extension, and sign in to ente.io or some other site that supports setting up FIDO as MFA. Ente.io calls it "passkeys". I'd prefer to avoid another discussion on the technical inaccuracies of the usage of that term, please.
- Select to register the FIDO credential with the service, and observe that the Proton Pass extension asks you to register a "passkey". Now accept that.
- On GrapheneOS, go to Settings > Passwords, passkeys and auto-fill > Select Proton Pass
- In Vanadium, go to settings > Autofill Options > select Other providers
- Sign in to the service in Vanadium
It's really very straightforward. And no, I don't have any chrome://flags set.
Upstate1618 I cannot register Proton non-passkey on GOS directly
Yes. That's why I created the guide in the first post of this thread. Perhaps you missed the details?
Upstate1618 From PC, I cannot register or authnticate passkeys and non-passkeys on GOS. I'm stuck at connecting your device after scanning QR code.
That's unfortunate, but please try basic troubleshooting first, such as rebooting your device.
Upstate1618 You cannot register passkeys on Yubikey from GOS.(This is different from stock).
You can, just not in Vanadium. See https://discuss.grapheneos.org/d/12056-fido2-security-keys-on-grapheneos-a-summary/4
Upstate1618 authenticate passkeys on Yubikey from GOS.
This works fine. See the thread I linked to above.
