I'm trying to set up a Yubikey for passworldless login. When I enable Passwordless, and then click on the 'Register USB security key' on the Set up USB security key page, I get a 'Something went wrong. Click Register USB security key to try again.' message. I have to close the tab, which results in a box coming up on my Vault page that says 'Something went wrong. We couldn’t enable USB security key. Make sure you’re connected to the internet and try again.' Could the Yubikey be defective?
