iPhone users can also get the privilege of using their devices as Google security keys for two-factor authentication purpose

In the last year, the tech giant Google launched its new feature of enabling all 7+ Android devices to be used as two-factor authentication (2FA) while signing into Gmail, Drive or any other first-party services of the Tech Company and this year Google just revealed a new update which enables iPhones to be used as built-in phone security keys for a variety of Google apps.

Nowadays, majority of the people rely on two-factor authentication of codes sent via SMS but despite that, it is also widely regarded as an insecure way of 2FA as phone number can be accessed easily so usually safer alternatives recommended for multi-step verification includes plugging physical keys into the phone or computers of the users.

To ease the users, Google just launched a new solution regarding two-factor authentication which is that the users can use their phone hardware to easily verify that they’re the one logging in.

If you take a look at the Google Prompt and built-in phone security key you’ll realize that even though they both pretty much share the same UI but they still differ from each other.

The push-based Google Prompt approach is found in the Google Search app and Gmail whereas the built-in phone security key approach is found to be pretty similar to physical USB-C/Lightning Key in terms of being more secured towards phishing attempts.

For the phone security key, the user needs within the specified Bluetooth range of the device that wants to log-in whereas the login prompt can’t be sent over with an internet connection so easily.

Recently this week, Google also launched another update in its Google Smart Lock app for iOS which includes enabling iPhone users to set up their phone’s built-in security keys storing Touch IDM Face ID and other cryptographic data with the Secure Enclave found on the A-Series chips of Apple.


Whenever an iPhone user will enter its Google Account username and password they’ll be directed towards open Smart Lock app on their nearby phones to confirm the login attempt and it also provides the user with the option to cancel the attempt by clicking on the button ‘No, it’s not me’.

This built-in security feature will only work if the user is signing-in to Google with Google Chrome app with enabled Bluetooth on the Desktop computer and phone as well for the confirmation of request and verification of the devices communicating locally.

After installing the update on the device, iPhone users will be directed towards the option to select an account to set up the built-in security key of the phone and previously, the Smart Lock app was only used to allow Bluetooth security keys along with generating one-time security codes but a version of 1.6 Google pretty much refreshed the app to make it easier to use for its users.

Google is one of the largest tech giants with billions of active users and the platform always attempts to provide its users with as many unique services as possible and we are really looking forward to more new services in the coming months.
