How to Use Google Authenticator: The Complete Beginner's Guide
Protecting your online accounts with just a password isn't enough anymore. Google Authenticator adds an extra layer of security that's easy to use once you know the basics.
What is Google Authenticator?
It is a mobile app that generates a 6-digit code every 30 seconds. This is called a Time-based One-Time Password (TOTP). When you log into a service, you'll enter your password PLUS this rotating code.
Step 1: Install the App
Download the official app from your device's store:
Step 2: Adding an Account
To secure a service (like Gmail or Amazon):
- Go to the security settings of that website on your computer.
- Look for "Two-Factor Authentication" or "2FA" and choose "Authenticator App".
- A QR code will appear on your computer screen.
- Open the app on your phone, tap the "+" button, and select "Scan a QR code".
Step 3: Logging In
The next time you log in, the site will ask for a code. Open the app, find the site name, and type in the current 6 digits before the timer runs out.
Pro Tip: View Codes on Your Wrist
If you have an Apple Watch, you can use GAuth Exporter to sync your Google Authenticator accounts to your watch. This allows you to get your 2FA codes without even touching your phone!
Crucial: Save Your Backup Codes
Every time you set up 2FA, the website will give you "Backup Codes" or "Recovery Codes". Print these or save them in a secure place. If you lose your phone and don't have these codes, you might be permanently locked out of your account.
Next Steps
Once you're comfortable with the basics, you might want to explore how to backup your codes or move them to a dedicated password manager for better organization.
