Two-factor authentication, also known as tokenless two-factor authentication, is a security method that uses two phases or forms of verification before secured data can be accessed. Its purpose is similar to that of single-factor authentication, except for one critical difference.
In single-factor authentication, there is no need to provide anything other than a username and password. In two-factor authentication, a username and password will be required, plus other information. This is to strengthen security measures and further protect information. You can also get the advanced authentication for lock law using 2 factor authentication via online sources.

How This Exactly Works
With authentication, a person keys in a username and password, then more data for identity verification purposes. At this phase, the person may be asked to enter a pass mark, usually to affirm that a user-associated image is being shown. Sometimes, a pass mark can be a question set by the user himself when he first created his login details.
The Important Need for It
With the increasing number of people transacting online, the risks are growing as well. When sending money through an online vendor, for example, both the sender's and the receiver's accounts' security could be compromised. Online payments made through credit cards could also increase security concerns for their owners.
Hackers are everywhere today, and they can easily steal bank account or credit card information when no reliable security measures are employed in using them. With hacking comes identity theft, which can have very serious consequences for the victim. Even offline, rising criminality rates have made it all the more important to employ tokenless two-factor authentication techniques for secured areas.
