Before we start, download Google Authenticator App.

When logged into your Google or Gmail account, click on your account icon at the top right of the screen. Then click Manage your Google Account.

Go to Security, next press on 2-Step Verification in the Security section.

Click on Get Started.

Next, you will need to renter your Google password and click on Next.

Enter your phone number and choose the method to get a verification code and click Next.

Google will send you a 6 digit security code. Enter that code into the verification field and press on Next.

Click on Turn On.

Now from available second steps options find Authenticator App, and click Set Up.

Choose the type of device you are authenticating with and click Next.

A pop-up window will appear for you to scan the QR Code with Authenticator App. Keep this window open as you reach for your phone. This is a good example of how other sites will prompt you to use Google Authenticator for two-factor authentication. While it makes sense that Google would want to promote their own app, remember that you can always substitute it with Authenticator App by 2Stable instead.

Open Authenticator App and at the bottom of the screen, tap the plus button and hold your device up to the computer screen to scan the QR code. If you are unable to scan the QR code, you can import the QR code in Authenticator from Files, tap the plus sign in Authenticator and choose Files and follow the instructions.

After successfully scanning the QR Code, Authenticator App will automatically choose the Google logo and autofill account name and secret key. If you want you can change the icon or the account name. Press on Save when ready.

Copy the numerical code provided from Authenticator App and confirm it on the Google website and then click Verify. Note that this code refreshes every 30 seconds.

You have successfully turned on 2-step verification for your Google account, from now on, you will need to use the Authenticator App when you log in.
