2FA methods supported in IOS 14.4.2

Is YubiKey OTP supported as 2FA by the IOS app?

And id it correct that the Security Key by Yubico is not yet supported by the IOS app, yet?

I haven‘t found precise answers in the help pages or the forum and wanted to make sure it works before I buy one.

Yubikey TOTP works on Mobile (ios/android), no problem! We just don’t have FIDO2/Webauthn for mobile yet, though it is in progress :slight_smile:

Many thanks for the answer!
