Within Teamwork Desk, you can disable two-factor authentication via your profile settings.
Click your profile icon in the top right corner of your site, and select View Profile from the dropdown menu.

Click the Edit Profile button in the top right of your profile area.

Scroll to Preferences at the bottom of your profile details, where you will see an option for two-factor authentication.

When you click Disable, you will need to get the authentication code from the Google Authenticator app for iOS or Android.

After you select Submit, you will see an alert in the bottom right of your Desk account confirming two-factor authentication has been disabled.

Note: Two-factor authentication is available on the Pro plan and above.
