The following steps will help you to enable two-factor authentication on your account.
Important: After two-factor authentication is enabled on your account, you will have to enter a six-digit code every time when you log in to your account. That code is not sent to your mobile device, meaning you won't get a notification on your mobile device. When you log in, you need to open the downloaded app on your mobile device, and read the six digit code as displayed in the app.
