Native support of NFC FIDO2 Keys in iPhone Safari
Starting from iOS 13.3 it’s now been confirmed that your iPhone will natively support NFC-enabled FIDO2-compliant security keys in Safari. With our NFC enabled FIDO2 keys, you can now log in to any website you have registered directly using your Safari browser without the need of an additional app (this applies to U2F and WebAuthN based authentication only, HOTP/TOTP based logins will still require the companion app).The video below shows how our NFC FIDO2 key is used on our FIDO2 Demo page.
Starting from iOS version 14, the PIN code enabled FIDO2 keys are also supported. If you have PIN code enabled on your NFC FIDO2 Key, you will have to tap your key twice (second time after entering the correct PIN) to complete the procedure.
The video below shows the same process with PIN code enabled on the key.
Please note that you can also use USB (directly or via adapters). However, it's important to note that our FIDO2 type C to Lightning adapter is designed to support FIDO protocols only, and not OTP. If you need to use OTP functionality with your key, you will need to use NFC instead. Additionally, if you are using your FIDO2 key's HOTP functionality, please be aware that it uses keyboard emulation, which may interfere with the process of entering your PIN code on iOS devices. As the device recognizes the security key as a keyboard, it may disable the on-screen keyboard, making it impossible to enter your PIN code. To avoid this issue, we recommend that you either disable the OTP functionality of your security key using our Windows companion app, or unplug the key when entering your PIN code.
Additionally, there is another aspect that appears to be more of an iOS GUI glitch. When an iPhone prompts the user to choose the passkey type, users should start using the FIDO2 key without following the on-screen instructions.
Specifically, when selecting the "Security Key / External Security Key" option, iPhones only search for NFC keys and disregard the USB-connected ones.
