A step-by-step walkthrough for adding your first account using a QR code — no Google sign-in required.
Before you start: Make sure Google Authenticator is already installed on your phone from the App Store (iPhone) or Google Play (Android). You’ll also need a QR code shown on another screen — typically from the website or service you’re securing.
Step 1 — Open the app and tap Get started
When you launch Google Authenticator for the first time, you’ll see a welcome screen. Tap the blue Get started button at the bottom of the screen.
Step 2 — Choose “Use Authenticator without an account”
Next, the app will offer to back up your codes by signing in with a Google account. Skip this by tapping the link Use Authenticator without an account below the blue button.
Why this matters: You don’t need a Google account to use Authenticator. Your codes will simply stay on this device.
Step 3 — Tap the + button to add a code
You’ll now see the main Authenticator screen, which is empty until you add your first account. Tap the blue circular + button in the bottom-right corner.
Step 4 — Select “Scan a QR code”
A small menu will slide up with two options. Choose the first one — Scan a QR code — to use your camera.
Step 5 — Point your camera at the QR code
The camera will open. Hold your phone steady so the QR code sits inside the square frame. It will scan automatically — there’s no button to press. You may be asked to allow camera access the first time.
Step 6 — Your code is ready to use
Once scanned, your account appears on the home screen with a fresh six-digit code that refreshes every 30 seconds. Type this code wherever the website asks for your verification code, and you’re done.
Tip: The circular timer on the right shows how long until the code refreshes. If it’s nearly empty, wait for the next code to avoid it expiring as you type.
One important reminder
Without a Google account backup, your codes live only on this device. If you change phones or lose this one, you’ll need to set up each code again. Most services provide backup codes when you first enable two-factor authentication — keep them somewhere safe.
