If you use the Vanguard mobile app, it will by pass the YubiKey and revert to 2FA via SMS. What would happen if I use the vanguard app on iphone? Is it possible to bypass the Yubikey (SMS, email,etc.)? I went through most of the discussion and didn't find an answer (apologies if I missed). Hmmm okay, then maybe I'll give that a try and see if I can get passed the error. I have used Yubi Manager to change a pin and that does work and the Vanguard login works with the new pin. I believe that if the key already has a fido2 pin in it then you won't be asked to enter and then reenter a new pin when you register the key. The old formatted site makes no overt mention of upgrading or FIDO2 though their terms of service do mention FIDO2ĮTA2: and it appears as if things are working correctly here ĮTA3: has anyone had any better luck setting a PIN via Yubi Manager first? I'm reluctant to try quite yet until I do more research. Both are supposed to support FIDO2Īnd yes that's my worry come 20 Sep if this can't be figured out.ĮTA: I'm not sure I ran into the bug you describe but instead I was re-registering my key on the old site (old format) where they also send you to delete keys, but the failure was happening on the new updated site where it uses the terminology about 'upgrading' my key. I'm using FF 104.b03 but I also tried MS Edge 1.77 (Official build) (64-bit) and got the same error. It is a YubiKey 5 NFC (not a 5c) website says it supported FIDO2. Since it let me register a Yubico Neo (an old key type that only support FIDO/U2F and not FIDO2/WebAuthn), I would be cautious counting on these keys to work after the September 20th cutoff date. What kind of key was it? Does it support FIDO2? I believe there is a flaw in their programing, and it will let you register a key that does not support FIDO2 pin functionality and not ask for a PIN.

So, I guess they are still allowing old-style registrations that way? Hmmm so I tried deleting one of my keys, then re-registered it from the same key management page and it didn't seem to ask for a pin.
