To set up Google Authenticator on an iPhone, follow these steps:
1. On your iPhone, open the App Store.
2. Search for "Google Authenticator" in the search bar.
3. Find the official Google Authenticator app and tap on it.
4. Tap the "Get" button to download and install the app.
5. Once the app is installed, locate the Google Authenticator icon on your home screen and tap to open it.
6. On the initial screen, you'll see a prompt asking if you want to let Google Authenticator send you notifications. Choose your preference and tap "Next."
7. You'll be presented with two options for adding accounts: "Scan a barcode" or "Enter a provided key." Choose one based on the instructions provided by the website or service you want to enable 2FA for.
- If you select "Scan a barcode," the app will open your iPhone's camera. Point it at the QR code displayed on the website or service to scan it.
- If you select "Enter a provided key," manually type in the account name and the secret key provided by the website or service.
8. After scanning the barcode or entering the key, the app will automatically add the account to Google Authenticator.
9. The app will now display a six-digit verification code for the account you just added. This code changes every 30 seconds.
10. Repeat the process for any additional accounts you want to set up in Google Authenticator.
With the accounts added to Google Authenticator, you can now use the app to generate time-based one-time passwords (TOTP) for two-factor authentication (2FA) when logging in to the corresponding websites or services.
Remember to securely store any backup codes provided during the setup process and consider enabling any available cloud backup options within the Google Authenticator app to protect against data loss or device changes.
