Google Authenticator is a free app that generates two-factor authentication (2FA) codes on your mobile device. Setting up Google Authenticator is a simple process that will help to secure your online accounts by requiring a second form of identification beyond just your password.
The first step in setting up Google Authenticator is to download the app from the App Store or Google Play. Google Authenticator is a free app that is compatible with both iOS and Android devices. Once you have downloaded the app, open it on your device.
Here is a step by step guide on how to download the Google Authenticator App:
- Open the App Store or Google Play on your mobile device.
- Search for “Google Authenticator” in the search bar.
- Look for the official Google Authenticator app, which should be developed by Google LLC and has a green icon with a white triangle.
- Tap on the “Install” or “Get” button to begin the downloading process.
- Wait for the app to be downloaded and installed on your device.
- Once the installation is complete, open the app.
- The app will ask for permission to access your device’s camera, allow it to proceed.
- You should now be able to see the interface of Google Authenticator app.
It’s important to make sure you download the official Google Authenticator app, as there may be other apps with similar names that could potentially be malicious. Once the app is installed, you are ready to set up 2FA for your accounts.
Adding an Account
Once you have downloaded and opened the Google Authenticator app, the next step is to add an account that you want to secure with 2FA. To do this, tap the plus sign (+) button in the upper right corner of the app’s home screen.
This will open a menu with several options for adding an account. The most common method is to “Scan a barcode”. This will open your device’s camera and allow you to scan a barcode displayed on the website or app that you want to secure. Once you have scanned the barcode, the app will automatically configure itself to generate 2FA codes for that account.
If the website or app does not provide a barcode, you can also manually enter the secret key. This key is a string of characters provided by the website or app that is used to set up 2FA.
Once you have added an account, the app will generate a six-digit code. This code will change every 30 seconds, and you will need to use this code to verify that the app is working correctly on the website or app you want to secure.
If the code is verified, you will be prompted to set up a backup method in case you lose your device or it runs out of battery. This is an important step as it will allow you to access your account even if you can’t access the authenticator app.
Using Google Authenticator
Once you have set up Google Authenticator and added your accounts, the app will generate a new six-digit code every 30 seconds. These codes are used as the second form of identification for your accounts.
When you log in to an account that you have set up with Google Authenticator, you will be prompted to enter your password as usual. Once you have entered your password, you will also be prompted to enter the six-digit code generated by the app.
To get the code, simply open the Google Authenticator app on your mobile device and look for the account in question. The code will be displayed next to the account name.
It’s important to note that the code generated by the app will change every 30 seconds, so you need to enter the code quickly before it expires.
In case you lose your device or it runs out of battery, you can use the backup method that you set up during the initial setup. This could be a phone number or an email address, to receive a code to access your account.
By using Google Authenticator, you can be sure that your online accounts are secure and can only be accessed by you. Two-factor authentication is a simple but effective way to protect your personal information and keep your accounts safe from hackers.
Backing Up and Restoring Google Authenticator

This is in case you lose your device or it runs out of battery, you can use the backup method that you set up during the initial setup. This could be a phone number or an email address, to receive a code to access your account.

It’s important to note that if you lose your device and don’t have a backup, you will lose access to all of the accounts that were set up in Google Authenticator. Therefore, it is crucial to set up a backup method as soon as you set up the app, to ensure that you don’t lose access to your accounts.
