How to use Google Authenticator on Windows 10

One of the best ways to protect your online accounts from being compromised is to use two-factor authentication (2FA). This adds a second layer to the sign-in process, requiring you to use a one-time generated code (usually generated on your smartphone) to successfully sign in with tools like Google Authenticator.

That is, of course, if you actually have a smartphone with Google Authenticator installed. Otherwise, your options are limited, but you can use Google Authenticator on your PC without another device. If you want to know how to use Google Authenticator on Windows 10, this is what you need.

Generate Google Authenticator secret code

If your username and password are exposed online, your account is at risk. Even using a password manager won’t help you at this point — you’ll need to change any passwords that were compromised in the breach.

To help fix this problem, you can link your online accounts to a two-factor authentication service like Google Authenticator. This generates a one-time password (OTP) to successfully sign in to Google and other online services.

It doesn’t matter if the password is breached if the hacker doesn’t have your 2FA credentials. 2FA adds another layer of security. To generate a code, you’ll need to set up Google Authenticator on your Windows PC using a third-party app and insert a secret code that matches your Google account.

The secret code is like the master password — without it, the generated codes won’t work to complete 2FA login. This code will only work for your Google account login, but you will need similar codes to link other online services with 2FA apps on your Windows PC.

  1. To find the secret code for your Google account, open Google account website. In the menu on the left, select Guard.

  1. At the next stage, you will see a QR code that you normally need to scan. However, you won’t do this, so choose Can’t scan it? instead.
  1. The secret code for your Google account will appear in the box below, which is a combination of 32 letters and numbers. Write it down or make an appropriate copy of it, then choose Next to continue. Keep this page open at all times as you will need it to complete the setup process afterwards.

Once you’ve saved the secret code, you need to install the 2FA app on your PC to continue.
