How to enable 2FA for TeamViewer
The best way to manage all your 2FA accounts is to use the Authy app. It enables you to have a single mobile app for all your 2FA accounts and you can sync them across multiple devices, even accessing them on the desktop. Install Authy on your device by searching for it in your device’s app store.
Important: If any sites prompt you to use Google Authenticator for two-factor authentication, note that you can always substitute the Authy 2FA app instead. Although they work in similar ways, Authy is more feature-rich and allows for multi-device syncing, cloud-backups, and easier account recovery should you change or lose your phone or device.

To locate the 2FA setting in TeamViewer, log into your TeamViewer account. Click on your account name in the top right corner of the screen. Then click on “Edit Profile.”
On the next screen, you will see your account information. Next to “Two factor authentication,” click “Activate.”
You’ll next see a short description of how Two-factor Authentication works with TeamViewer. Once ready, click “Start Activation.”
On the next screen, you’ll prepare to capture a QR code. Leave this screen open while you grab the Authy app on your phone or mobile device.
To capture the QR code, launch Authy on your device. Click ‘Add Account’ at the bottom of the screen. You’ll be prompted to hold your phone up to your computer to capture the QR code on the TeamViewer site. Once the QR code is captured, Authy will display your TeamViewer account. When ready, click ‘Done’.
Return to the TeamViewer screen on your computer and click “Next.”
You will now be shown Recovery Codes that you should keep in a safe place. Download, Print, or Copy them, and then click “Continue.”
On the next screen, you will be prompted to enter the numerical security code from your TeamViewer account on the Authy app. When done click “Activate.”
If successful, you will see a confirmation pop up on your computer screen. Click “Close.”
Back at the TeamViewer account profile page, you will now see that Two-Factor Authentication is now activated.
