Set Up Multi-Factor Authentication with Google Authenticator

Overview

If your company uses Google Workspace, multi-factor authentication (MFA) protects your account by requiring a six-digit code from your phone in addition to your password. This guide walks you through setting up Google Authenticator as your second factor.

Before You Begin

• Your work Google account email and current password.
• Your smartphone with the Google Authenticator app installed.
• Five minutes of uninterrupted time.

Steps

1. On your phone, open the App Store (iPhone) or Google Play Store (Android).
2. Search for Google Authenticator, published by Google LLC. Install it.
3. On your computer, open a browser and go to https://myaccount.google.com/security.
4. Sign in with your work Google account.
5. Under How you sign in to Google, click 2-Step Verification. Click Get started if it is not already on.
6. Re-enter your password if asked.
7. Scroll down to Authenticator app and click Set up.
8. Choose Android or iPhone, then click Next. A QR code will appear.
9. On your phone, open Google Authenticator. Tap the + button, then Scan a QR code.
10. Point your phone's camera at the QR code on your computer.
11. Your account will appear in the app with a six-digit code that refreshes every 30 seconds.
12. Back on your computer, type the current six-digit code into the box and click Verify.
13. Save your backup codes. Click Show codes, then print them or save them in your password manager. You will need these if you lose your phone.

Troubleshooting

• If the code is rejected: the time on your phone may be out of sync. In Google Authenticator, tap the menu, then Time correction for codes → Sync now.
• If you do not see the +" button: make sure you have the latest version of the app from the official store.
• If you lose your phone: sign in on a computer and use one of your backup codes. Then set up Authenticator on the new phone right away.
• If your company requires a hardware key instead: see "Use a Hardware Security Key for Multi-Factor Authentication."
