**List of steps to reproduce** (step by step, including full links if applicable):
* Register a YubiKey Security Key NFC via USB on a desktop browser on en.wikipedia.org
* Try to log in with the key in Safari on iPhone X, iOS 15.0 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.
**What should have happened instead?**:
It should have recognized my security key via NFC.
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc**:
English Wikipedia, iPhone X, iOS 15.0, Mobile Safari
