In iOS 13.3, Safari now supports security keys compatible with NFC, USB, and Lightning FIDO2 technologies.
Support actually came with the first beta release, but Apple has now given more details about the newness in the operating system release notes, as reported. MacRumors.
What does that mean? Very soon, when iOS 13.3 is released to everyone, Apple's mobile browser will be compatible with accessories like YubiKey, equipped with Lightning connector, which can be used for even more secure two-factor authentication. When using such a key, you do not even need to enter the code since everything is done automatically and securely.
