OpenVPN and Yubico (TOTP) without Authenticator App

Security
1

Hi there,

I am running a IPFire Firewall.
I want to add a openvpn authentication method with a Hardwaresecuritytoken like the Yubikey.

I have the opportunity to generate this with the option TOTP and the Authenticator app.
My question is, can i set up my Yubikey to generate the token without the Authenticator app?

Maybe we have another option :slight_smile:

Thankyou
