If you have enabled two-factor authentication (2FA) and you've lost access to your authentication device (e.g. your smartphone), that's unfortunate! But don't worry, we're here to help.
Please send an e-mail to firstname.lastname@example.org from your Homey account's e-mail address, with a watermarked copy of a government issued identification document, such as a driver's license or passport. We'll then disable 2FA on your account so you can log in again.
