XLS Padlock with Yubikey and generic FIDO U2F Security Key

Is it possible to add Yubikey or a generic FIDO U2F Security Key as additional option for protection with hard keys?
Protection with USB stick is not good enough since these sticks are easily to be cloned.
Going with Enky SL dongle only is not really a good business decision since we hardly get a good deal with that single player in the market, or worst Enky might go out of business then we would be stuck.

Yes there are many alternative to Yubikey out there (examples: Fido U2F Security Keys), but even less expensive fido keys still can end up with a fair cost (given you normally end up being advised to purchase two keys - so that one is a backup).

There is an alternative that is becoming popular, and that is to use your smartphone as a FIDO2 device. For this your phone is registered as a "passkey", and given most people carry a suitable phone around with them this might be an option worth considering.

Another alternative that is popular is to use a TOTP key on an authentication app. From a security point of view dedicated hardware has many advantages, but for widespread adoption offering alternative authentication options is probably the best bet (then if the users have already purchased a fido key then can simply choose this option).
