How to Use Android Phone to Verify Google Sign in on iOS Using 2SV

Google recently introduced 2SV or two-step verification, a new way to enhance the security of your Google sign-in process. Similar to a Yubi key, 2SV replaces the need for a USB device by utilizing your Android smartphone instead. Whenever you sign in to a Google service on your iOS device, a pop-up notification will appear on your Android phone, providing you with essential details and the option to accept or reject the sign-in attempt. In this article, we will explore how to implement 2SV on an iPhone and how to set up your Android phone to sign in to various services.

Prerequisites

Before setting up 2SV on your Android and iOS smartphones, there are a few requirements to be met. These include having Android 7 or higher, enabling 2FA in Google, having the latest version of iOS installed, downloading and installing Chrome on both devices, and enabling screen lock on both Android and iOS. By meeting these prerequisites, you can ensure a smooth setup process and enhance the security of your Google sign-ins.

Setting Up 2SV

To begin the setup process, sign in to your Google Account or create a new one. Once signed in, navigate to “My Account” and go to the Security tab. Here, you will find the option to “Use your phone to sign in” under which you can set up 2-Step Verification. Follow the on-screen instructions to enable 2SV on your Android phone.

After enabling 2SV, you will be prompted to enter your Google account password for security reasons. Once entered, you will see a drop-down list of smartphones associated with your Google ID. Choose your Android phone as the device to use for signing in. It is crucial to have screen lock enabled on both your Android and iOS devices to ensure maximum security. After confirming the screen lock, you will be able to test the newly enabled 2SV feature by entering your Google email ID. Google will send a notification to your Android phone to verify if sign-in using your smartphone is working properly.

Real-World Testing

Once the setup is complete, unlock your iPhone and try signing in to your Google account on an app or website using the same Google ID. You should receive a Google prompt on your Android phone, displaying details such as location, time, and device OS. This prompt allows for faster sign-ins compared to entering 2FA codes manually. Not only does it save time, but it also provides an additional layer of security.

Backup Options

In case your smartphone is stolen or misplaced, Google offers backup options to ensure you can still receive 2SV prompts and sign in to your accounts. One option is to receive an SMS code on a different mobile number. To set this up, go back to Google My Account, navigate to the Security tab, and select 2-Step Verification. From there, you can add a backup number to receive SMS codes for signing in to apps and sites on your iPhone.

Another option is to use backup codes, which are one-time passwords that can be used for signing in. It is recommended to print these codes and keep them offline for added security. Additionally, Google offers the Authenticator app, which can generate codes offline, eliminating the need for an active internet connection. Lastly, you can use a physical USB security key for the most secure form of authentication. Adding a Yubkey as a security key is highly recommended.

Google 2-Step Verification

Usernames and passwords are no longer sufficient to ensure security. Implementing a second layer of protection is crucial, and there are several ways to achieve this. Two-factor authentication (2FA) is a secure option, but it requires entering a generated code from an authentication app after entering your password. 2SV, or two-step verification, solves this problem by using your Android phone as a physical key. With a simple tap on the pop-up notification, you can quickly complete the sign-in process. However, it is always wise to set up a backup method in case you lose access to your Android phone.

By following the steps outlined in this article, you can use your Android phone to verify Google sign-ins on your iOS device. This setup provides an additional layer of security, making it more difficult for unauthorized individuals to access your Google accounts.
