Within Teamwork.com, you can disable two-factor authentication for your profile via your profile settings.
When turned off, you will no longer be required to enter a verification code from the Google Authenticator app after entering your password.
Click your profile icon in the bottom left corner of your site and select Edit My Details from the menu.

In the edit details modal, go to the Account tab where you will see an option to disable two-factor authentication.

When you click Disable, you will be prompted to enter the verification code generated in the Google Authenticator app.
Once entered, click Submit to complete the process.

A pop-up alert will appear in the bottom right of your site confirming that two-factor authentication has been disabled.
