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.
In your profile area, select the Profile tab from the left pane.
Scroll to the bottom of your profile details, where you will see an option for two-factor authentication, with a link to disable.
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 is disabled.
Note: Two-factor authentication is available on the Plus plan and above.
