2FA Setup Guide

How to enable 2FA for your Google account

Updated June 5, 2026

Two-factor authentication (2FA) protects your Google account even if your password leaks. Follow the steps below to generate Google verification codes with the Authenticator App on your iPhone, iPad or Mac.

  1. Download Authenticator App

    Download Authenticator App from the App Store on your iPhone, iPad or Mac. It's free and no sign-up is required.

  2. Open your Google Account settings

    On a computer, go to myaccount.google.com, or click your profile picture and choose “Manage your Google Account”.

  3. Go to Security and open 2-Step Verification

    Select “Security” in the left menu, then under “How you sign in to Google” click “2-Step Verification” and follow the prompts to turn it on.

  4. Choose the Authenticator app option

    From the list of second steps, find “Authenticator app” and click “Set up”. Google will display a QR code.

  5. Scan the QR code with Authenticator App

    Open Authenticator App, tap the + button and scan the QR code shown by Google. If you can't scan it, choose the manual option on Google and type the setup key into the app instead.

  6. Enter the 6-digit verification code

    Type the 6-digit code from Authenticator App back into Google to confirm the setup. The code refreshes every 30 seconds.

  7. Save your backup codes

    If Google offers backup or recovery codes, download or write them down and store them somewhere safe. They let you regain access if you ever lose your device.
