Access Two-Factor Authentication settings, or click the settings icon in the left-hand bar, then click “Application Settings”.
Then, click “Edit your Account.” This will bring you to your Nulab account.
From there, click on the ‘Security’ tab. You should see a section called ‘Two-factor Authentication’. Since you have not done anything with it yet, its status should say ‘Disabled’. Then, you’ll want to click ‘Start Two-Factor Authentication.’ You can select to initiate the verification code process either via text message or from a mobile app.
