I use FIDO2 hardware tokens for multi-factor authentication from my Android phone, Chromebook and Mac's when accessing various online sites and services.

Recently went around in circles trying to get my wife's iPhone 14 Pro with the old Lightning connector to authenticate and do the same. The FIDO hardware token supports both NFC and physical USB-A. Her iPhone would not connect OTA with NFC and could not be physically connected with the USB-A cable.

I ended up purchasing an inexpensive 5-in-1 universal OTG adapter and SD card reader for iPhone/iPad, USB-C and USB-A devices. Once I connected the hardware token with the cable, it authenticated as expected. This stuff is infinitely easier with mobile phones that have a USB-C connector (and NFC "just works" (and can be disabled/enabled as needed) on Android)!
