Hi,

We are on **v1.32.4469.94** from unstable and Yubikey doesn’t work.

We get to the screen “please insert YubiKey” but when inserted it is not recognised and the key doesn’t blink

The key works on the yubikey test site

Thanks

The Pritunl VPN uses OTP not WebAuthn, this doesn’t prompt the device or cause the light to blink. It should be pressed and this will fill the input with the OTP code. The [**Yubico OTP Test**](https://demo.yubico.com/otp/verify) can verify is this is working. For Pritunl Zero and Pritunl Cloud these do use WebAuthn and should prompt for the key.
