Two-step verification is simply using two different methods of signing in to a website or an app. Typically the first method is a username and password. The second method is an additional piece of information to which only that specific user would be able to gain access. For example, a code sent via text to a smartphone or a code sent to a secondary email address. Two-step verification typically isn’t a default setting, so it has to be set up after you have created an account.
While it can prolong the login process, taking this extra step can help prevent your account from getting hacked. Even if the potential hackers are able to figure out your username and password, they may not be able to get access to the second factor that is required to login to your account.
Many websites and apps use two-step verification when you are signing in from a computer or device that they do not recognize, therefore you would only need to complete the second step the first time that you login from a new device.
