Currently Connectwise Control supports the following 2FA types: Email & SMS, Google Authenticator, YubiKey, Microsoft Authenticator, LinOTP, Duo Security.
It would be great if we could have U2F (Universal Two Factor) authentication added. While the Yubikey OTP option is available, it means non Yubikey hardware devices cannot be used.
Google is about to launch its own security key: The Titan security key.
Obviously browser support is a bit of an issue at the moment, but it has not stopped Google, Facebook, Dropbox among others from launching support of U2F.
For your consideration.
