If your device used for authentication has been lost, stolen, destroyed or rebooted or your authentication app has been disconnected from your Mintos account, check which options for restoring your app data are available in your authentication app. If no such options are available, please contact our support team. Once we confirm that it is really you contacting us, we will disable two-factor authentication on your account. You will then be able to log in and connect a new authentication device.
Google provides some additional security tips for common issues with two-factor authentication.
