Two Factor Authentication is a way to verify the identities of users through a combination of passwords, logins, and another authentication factor. If a user positively authenticates themselves through two factor authentication, they are then granted access to the application and data.

Two Factor Authentication (TFA) requires authorized login details from users to ensure they are who they say they are. A standard, single factor authentication system typically only requires a login and a password (the single factor) to provide authorization. Two factor authentication goes a step further and requires another piece of unique information before a user is verified and granted access.
There are several ways to provide a second type of authentication, including:
TFA is much more secure than single factor authentication, because even if a hacker is able to steal password and login information, it is very challenging to provide that second, vital credential.
Multifactor authentication is a further step up from TFA and can involve providing an additional two types of credential in addition to the login and password.
