Security Key Support for 2fa
In the release notes for the iOS/iPadOS v7.8 release, the following is stated:
Another great feature now available for 1Password members using the latest version of iOS and iPadOS is the ability to use a security key with Lightning, USB-C, or NFC as a second factor when authorizing your 1Password account on a device.
and
* Support for two-factor authentication using Security Keys on all iOS 15 devices, including USB-C iPads.
What changed in iOS 15 (or in this release) in order to enable this functionality for USB-C iPads? I'm specifically asking here because, according to Yubikey support, nothing changed in iOS 15 to enable additional support for their security keys on USB-C iPads.
