Two-factor authentication adds a layer of protection to the standard password online identification method. You simply add another identification feature alongside your password and it’s usually a phone number. It’s free and quick and easy to do. Critics point out that because you usually have to use your phone number it’s just one more bit of information you’re handing over to a third party. This is true, but as hacks and database breaches become increasingly common it’s also one of the most practical and simple protection options available.
However, if you introduce two-factor authentication into your accounts it becomes much more difficult, by several orders of magnitude, to access the account. The password acts as the first line of defense – so toughen it up – and the second factor adds another barrier by introducing what is usually a phone number.
