I’m facing a strange issue - I cannot register Yubikeys (I’m using series 5, and have 4 of them) as passkeys on any discourse forum. I’m able to register my Android phone’s passkey and my Password Manager’s passkey successfully.
When I try to register Yubikey I get the below error, always:
@pmusaraj Yes, I have successfully registered them on Google, GitHub, Vercel, and a couple more services and they work fine.
@sam Yubikey Series 5 is a good candidate for passkey because it combines something I know (PIN) and something I have (the token itself) to use as a passkey. It won’t even list the resident keys without the PIN. The bio series replaces the PIN with biometric.
Thanks for checking @rishabhlakhotia. I see the errors in our logs on meta and the location of this failure is a general security key attestation function that hasn’t had any changes since four years ago. It’s used by the 2FA security key process as well.
Are you able to register the Yubikey as a two-factor authentication security key here on meta?
Yes, I have all four Yubikeys registered as Security Keys. To possibly avoid any edge cases, I tried again by removing two of them as security keys to re-register them as passkeys, but even that did not work.
I have YubiKey 5C NFC (5.4.3), and I use Chrome browser.
