Google announced on June 3 (local time) that it will roll back a change that will enable native support for the Google account W3CWebAuthn, or passwordless web authentication API, on Apple products since iOS 13.3. It means that you can log in by touching the security key on your iOS device.
When logging in to a Google account on the iOS device, a password is required and stable login is possible using a Google Titan security key. PC and Android were already responding, but this time iOS devices are also responding.
The security key is literally a dedicated hardware that plays a key role for security authentication. It works by connecting to the authentication device via Bluetooth and USB. The Titan security key can be used as a device for two-step authentication in services such as Dropbox, Facebook, and Twitter, in addition to Google, for security that meets the FIDO2 standard. The simple and powerful protection offered to individuals and businesses can now be enjoyed on iOS devices.
Among the Titan security keys, USB type A and Bluetooth type have built-in NFC functions, so you can log in by simply touching the back of the iPhone.
Meanwhile, since iOS does not support Bluetooth-type security keys and smartphones by default, you need to install a smart lock application on the iOS device side to use it. Google is the target of this support, but in fact, Apple has already supported FIDO2-compatible physical security keys in Safari since iOS 13.3. In other words, it was already possible to set up two-step authentication and authenticate with Google’s other services by plugging the Lightning connection key into the terminal. In this respect, it can be understood that the width of the effective security key is wider.
The Titan security key was released to the market as a product after Google made it mandatory for employees to use it, showing zero performance in phishing damage. If you are in a position to manage not only individual but also organizational information, you may be able to consider the introduction with the expansion of support for iOS devices.
