Add U2F/FIDO2 Token Support
With the recent release of OpenSSH 8.2, native U2F/FIDO2 token support now exists on the server's end. The client, of course, must also support this. As Termius is my most-often used client, it would be incredibly valuable from a usability and security standpoint if Termius could be updated to utilize U2F tokens for MFA. The capability already exists on all common host OSes: Windows, macOS, Linux, iOS, and Android. It would only need to be added to the app itself.

100% agreed. I would add that not only USB/Lightning connections for mobile, but NFC as well for Android (seems like the most common security key for Android users is the USB-C Yubikey 5 or the USB-A/NFC Yubikey 5).
Would have been nice if the clients were more proactive than reactive with implementing this, but I like Termius too much to complain.. Very excited and hopeful this gets implemented soon!
