How to Use Google Authenticator
1.Download the Google Authenticator App
The Google Authenticator app is available on both the Google Play store as well as the iOS App Store. It’s free to download and use, so there’s no need to pay any subscription fee. I recommend you download the app on your phone instead of a tablet, since you’ll need to have the device always with you when a code is required.
2.Locate 2-Factor Authentication Settings
Within the security settings of many online accounts, you’ll find an option for 2-factor authentication (2FA). Most major social platforms (Facebook, what'sapp, Instagram, Twitter, linkedIn, snapchat), email providers and investment accounts will offer 2FA, but not all of them do. In the example here, you’ll see the 2-Factor Authentication settings from within Facebook.
3.Scan the QR Code or Enter Code Manually
When you set up Google Authenticator for 2-factor authentication, the account security settings will either display a QR code or a 32-digit code (or both).
Click the “+” button on the top right corner of the Google Authenticator app and choose “Scan barcode”. If you only have one device, you can manually set up your 2FA codes with the code.
4.Confirm 2FA Code
After the QR code has been scanned or the 32-digit code entered, you’ll see the new account show up on the home screen of the Google Authenticator app. In the account settings where you’re attempting to set up 2-factor authentication, click “Next” or “Continue” where you’ll usually be asked to confirm the code has been set up correctly.
5.Use the Google Authenticator 6-digit code to Sign In
At this point, your 2-factor authentication has been configured and the app has been set up properly. Depending on your settings, you may be required to enter this 6-digit code every time you log in, every time you set up a new device or even just once every set period of days/weeks.
Pro Tips for Using 2FA Authenticator Apps
While the app itself is very simple, there are a few pro tips I’ve learned from using the app for the past couple of years.
• App Security: The Google Authenticator app does not require a password or biometric data (Face ID, Fingerprint, etc.) to open. This means that the app’s security is dependent on how well you secure your phone. Make sure you have at least a 6-digit code to unlock your phone.
• Backup Codes are Important: Scanning the QR code is by far the most convenient way to set up Google Authenticator. However, it’s important that you keep the manual code in an extremely safe place in the event that your phone gets lost or stolen. These backup codes could save you a ton of headache in the future!
• Use Multiple 2FA Options: For most online accounts, you’re not restricted to just one form of 2-factor authentication. For example, you could set up Facebook with both the Google Authenticator as well as with a 2FA security key. Either could be used to verify your account and act as a backup for each other.
• Tap to Copy the Code: Usually, 6 digits is pretty easy to remember, but not always. If you’re logging on to an account from your phone and it requires you to open the authenticator app for a code, simply tap the appropriate code and it will be copied to your clipboard. Now you no longer have to remember it!
