List of steps to reproduce (step by step, including full links if applicable):
- Register a YubiKey with FIDO U2F support via USB on a desktop browser on en.wikipedia.org
- Try to log in with the key in Mobile Safari or the Wikipedia app on an iPhone with NFC
The mobile site says verification failed, while the desktop site says authentication was interrupted. The iOS app just says "Please touch your verification device ..." but doesn't recognize it either. The iOS native NFC / security key UI never shows up.
What should have happened instead?:
It should have recognized my security key via NFC.
