2FA has long been used to control access to sensitive systems and data. Online service providers are increasingly using Two Factor authentication to protect their user's credentials from being used by hackers who have stolen a password database or used phishing campaigns to get users' passwords.

Authentication Factors:

There are hundreds of different ways in which someone can be authenticated using more than one authentication method. Most authentication methods recently depend on knowledge factors, like traditional passwords, while two-factor authentication (2FA) methods are added either as a possession or an inherence factor. Here is the list of authentication factors.

A Location Factor:

It is donated by the location from which an authentication attempt is being made. It can enforce by limiting authentication attempts to particular devices in a specific location or, more commonly, by tracking the geographic source of an authentication attempt based on the IP address or some other geo-location information.

A Time Factor:

This factor restricts the user authentication to the particular time frame in which logging on is permitted and restricts access to the system outside of that time window.

A Possession factor:

The user has, like ID card, a security token, a cell phone, a mobile device, or a smartphone application, to verify authentication requests.

After determines, which 2FA method is best for you, here is a quick rundown about the working of 2FA.
