Login With Passwordless Doesn't See Yubikey

Question

The situation: I enabled LastPass Authenticator and set up a Yubkey. In Passwordless Options I have Passwordless login on this device Enabled. Under Passwordless enabled devices it shows Current device: EdgeCR - Windows. When I attempt to login, it shows the Login With Passwordless option. When I select that, it goes directly to a page that says Something went wrong. Click Authenticate to try again.' Clicking authenticate does nothing. Clicking the 'Having trouble?' drop-down menu shows a large AUTHENTICATE button and the text 'Insert your YubiKey in the USB-port with the USB-contact facing upward. Wait until your YubiKey touch-button shines with a steady light. Hold your fingertip on the touch-button for 1 second.' Doing this populates the Passcode field with a long string, which then logs me in.

So I'm not seeing anything that allows me to enter a passkey to actually use the Yubikey for Passwordless login. Disabling Passwordless does allow me to login using my password, and I have tried setting up the Yubikey again, but a 'Nice! Passwordless is ready to use' box immediately comes up with no setup done, and I again have the above problem.

I was hoping to be able to use a Yubikey for passwordless login (as well as MFA). Any suggestions or help would be greatly appreciated.

Hello @wfgds,

Thank you for your message.

That is correct at the moment one YubiKey can be set up at a time to use FIDO2 authenticator for the passwordless login process. You can find more here:

Verlaine,

I got LastPass to recognize the YubiKey as a passwordless option. Is it correct that only one YubiKey at a time can be enrolled as a FIDO2 authenticator for passwordless login?
