What is two factor authentication?2FA is an extra layer of security that is put into practice to make sure that people trying to gain access to an online account are who they say they are. Typically, a user will enter their username and a password like they would on any other typical website or app. Then, instead of immediately gaining access, they will be required to provide another piece of information. This second factor could come from one of the following categories:• Something you know: This could be a personal identification number (PIN), a password, answers to “secret questions” or a specific keystroke pattern• Something you have: Typically, a user would have something in their possession, like a credit card, a smartphone, or a small hardware token.With 2FA, a compromise of just one of these factors won’t unlock the account. So, even if your password is stolen or your phone is lost, the chances of a someone else having your second-factor information is highly unlikely.
