How to get the security code?

The security code is generated by an authenticator app on your (mobile) device.

After activating two-factor authentication for your TeamViewer account, the app generates a temporary security code every 30 seconds. When you want to log in to your TeamViewer account, you have to enter the security code displayed on the app at this time.
