Add support for FIDO2 / FIDO U2F

Currently there is 2fa support for Trading212 accounts with TOTP but this method’s main flaw is that it is susceptible to fhishing. A better 2fa method would be to support the use of a FIDO U2F security key. Even better, if FIDO2 security key support is added, it would completely eliminate the need for passwords. These methods of authentication are vastly more superior to TOTP and passwords.


Absolutely. My preference would be for something that supports Websuthn but if the solution is a bit more proprietary (eg Yubikey) then that’s better than nothing.
