With two factor authentication, you will typically be required to provide a mobile phone number. When you login in from an unfamiliar device, you’ll receive a unique code that you’ll use to verify your account. It’s obvious that this simple step is worth the little effort required to set it up. But which accounts should you enable it on? Here’s how to enable two-factor authentication on six popular accounts offering this must-have feature.
