iOS users can now sign-in to Google accounts with USB/NFC security keys

Google is a big proponent for 2-Step Verification, and is improving the experience on iPhones. Users will be able to just tap an NFC security key to the back of an iPhone when prompted after entering their username and password. USB-C models can also be plugged in directly on compatible iPad Pro devices, while you can use Lightning to USB adapters for keys that were previously only used with desktops/laptops.
