The latest iOS 13.3 and iPadOS 13.3 is available for both developers and public beta testers. The release notes mention that Safari will start supporting NFC, USB, and Lightning FIDO2-compliant security keys. Apparently the feature debuted on iOS 13.3 Beta 1 but was mentioned on Beta 2 release notes.
Now supports NFC, USB, and Lightning FIDO2-compliant security keys in Safari, SFSafariViewController, and ASWebAuthenticationSession using the WebAuthn standard, on devices with the necessary hardware capabilities.
In other words, Safari will support physical security keys including the Yubico Security key. Typically hardware-based security keys are much easier and faster to use then two-factor authentication. Furthermore, hardware security keys boast of better security with FIDO U2F, security protocol that was jointly developed by Google and Yubico.
All you need to do is plug in the security key into Mac, iPhone or iPad and authenticate. Meanwhile, other security keys based on Lightning security, NFC and USB will also work. With security keys, you can protect and secure your computer networks whilst accessing online services. The security key works by generating a new pair of keys for every service while the service stores only the public key. It enforces a strong additional layer of security for your phones and computers. Security key also protects you from phishing, hijacking, man-in-the-middle and malware attacks.
