Google Smart Lock iPhone: Now you can use your iPhone as a physical two-factor authentication (2FA) security key. You can use it for logging in to Google’s first-party services in the Chrome browser on another device.

But thanks to the version 1.6 update to Google’s Smart Lock app for iOS.

Now use a Bluetooth security key or set up the security key that’s built into your iPhone. “Using this new update setting up your phone’s built-in security key the amazing second-factor protection for your Google Account.”

It works only if you’re using Google’s Chrome browser and when logging in to a first-party Google service. However, this feature can’t support other browsers or when using your Google account credentials to log in to websites and apps.

After setting up the app by choosing your Google account with the. 2FA protection turned on. And giving Bluetooth and notification permission, allowing you to log in to a Google service on one device. As your Mac will automatically send a notification with a one-time security code to your nearby iPhone. For both devices having Bluetooth in their Settings app and be in relative proximity to each other.

According to Google Cryptographer:

A Google cryptographer explained on Twitter that this latest feature of the Google Smart Lock app takes benefit of the unique device code stored in the Secure Enclave. The cryptographic coprocessor root in Apple’s A-series chips that’s a block off from the rest of the system. The Secure Enclave is used in all iPhones from the iPhone 5s onwards.

2FA (Two-factor authentication) provides an extra layer of security for your account by obtaining a one-time code after logging in. It uses your Google user name and password credentials on a new device. These codes can be sent via SMS, but they are not secure. To start with or pushed to one or more devices designated as your trusted hardware.

Safari on iPadOS, iOS 13, and macOS Catalina 10.15 or later supports physical security keys. These keys work over USB-C or Lightning. Like Yubico’s NFC-based physical security keys for passwordless login and 2FA (two-factor authentication).

Google Smart Lock is a free download from the App Store.

The app requires iOS 10 or later.
