You can set up your Two-Factor Authentication here.
In order to set up Two-Factor Authentication, you must have either a confirmed email or a confirmed phone number attached to your account. If you have just created your account, you will not be able to active Two-Factor Authentication until you confirm email or phone number. Afterwards, simply select the Enable button to allow Two-Factor Authentication. Once this has been enabled, when you log in next, it will send you an email, SMS message, or both (depending on what you have confirmed for your account) that will contain an authentication code to allow access into your account.
