Google Authenticator on PC: how to get your codes on a computer
SHORT ANSWER
Is there a Google Authenticator for PC?
Google's help describes Google Authenticator as an Android and iOS app and does not describe a Windows, Mac or web version. You normally read the code on your phone and type it on the computer. Other ways to get codes on a PC exist, such as password managers, but they trade away some security.
Key takeaways
- There is no official Google Authenticator app for Windows or Mac in Google's help. Downloads that claim to be one should be treated with suspicion.
- The simplest and strongest way is to read the code on your phone and type it on the computer.
- A code generator on the same computer as your password weakens the point of a second factor.
- If you must use the computer, use a reputable password manager with a strong lock, and keep a phone backup too.

The short answer
Google Authenticator is a mobile app. Google's help describes it for Android and iOS and gives no desktop or web version. When you sign in on a PC, you open the app on your phone, read the six-digit code and type it on the computer. That works because the second factor lives on a separate device.
Why separate devices matter
The purpose of a second factor is that a thief needs two different things. If your password manager, your passwords and your code generator are all on one computer, malware or someone at your keyboard gets both at once. A phone and a PC are two separate things to attack.
Ways to get codes on a PC, from safest to riskiest
| Way | How it works | Trade-off |
|---|---|---|
| Read it on your phone | Open the app, type the code on the PC | Safest. Needs the phone nearby. |
| Passkey on the phone | Scan the PC's QR code with the phone camera and approve | Strongest. Needs a site that supports passkeys. See the passkey setup guide. |
| A password manager's built-in codes | A manager such as Bitwarden, 1Password or KeePassXC can store the secret and show codes | Convenient. Passwords and codes sit together, so protect it with a strong lock. |
| A desktop authenticator app | A program on Windows, Mac or Linux that makes codes | Secrets sit on the computer. Only use a well-known one from its official site. |
| A browser extension | An add-on in your browser makes codes | Weakest of these. See the extension article. |
Avoid fake downloads
- Do not install a program or add-on that claims to be "Google Authenticator for PC" or "for Windows". It is not from Google.
- A fake authenticator that holds your secrets can hand them to an attacker.
- Check the publisher and the official site before you install anything that holds secrets. See authenticator app download: how to get one safely.
If you want codes on both phone and computer
- Pick one source of truth, ideally the phone.
- If you add a second copy, add it when you set up the account, by scanning the QR code in both places, so both generate the same codes.
- Treat the computer copy as lower trust: use it for accounts whose loss you can recover from.
- Keep recovery codes and an encrypted backup as well. See what to do if you lose your phone.
Frequently asked questions
Can I use Google Authenticator on Windows?
Google does not describe a Windows app in its help. Use the phone app and type the code on the PC.
Can I get my Google Authenticator codes on my computer without my phone?
Only if you set up a second copy beforehand, for example in a password manager, or use recovery codes. Otherwise you need the phone.
Is a Google Authenticator Chrome extension official?
Google's help does not describe one. Treat extensions with that name as unofficial and check the publisher.
Is it safe to keep codes in a password manager?
It is convenient and reasonable with a strong lock, but you lose the separation between password and code.
