Two-step verification, also known as two-factor verification, provides an extra layer of security by requiring users to prove their identity by entering a second form of authentication in addition to a password to access accounts.
While there are several credential options available, many online services, including Google, Twitter and Facebook, will text a randomly generated four-digit code to users' phones as a second factor every time they try to log in to a device not already associated with the account.
