Login to your account, go to “My Profile” and click on “Security” and activate 2FA with the generated token.
When you enable 2FA, it will provide you with 10 codes. Make sure you copy these codes for future use. For eg. if you lose your phone, codes will help you to get access to your business account and reactive 2FA on a new device. Each code works one time only. You will have 10 chances with 10 codes.
