What is two factor authentication?

Two Factor Authentication is an easy way for businesses and individuals alike to protect their data from unauthorized access. Multi-factor authentication is a form of electronic authentication in which an authorized computer user is given access to a website or program only after successfully providing two or more factor authentication codes to an authentication system: knowledge, ownership, and ineligibility.

This type of authentication not only provides greater levels of security to information and documents but also enables organizations and individuals to use more than one factor at a time. Using two-factor authentication allows for the use of both username and password for sensitive areas of information.

OTP(Online Transaction Protocol):

One of the most common methods of two-factor authentication is OTP (Online Transaction Protocol). A client using OTP may use one of the available authentication protocols to verify the integrity of the transmission and may also make use of other factors as well.

The client and server applications may both initiate the use of two-factor authentication before granting access. Using OTP, information can be encrypted and exchanged between the server and the client to ensure security.

With a two-factor authentication system, a hacker will not be able to use the victim’s account without the authorization of the business or the user.

Web Application:

Another way of securing data through two-factor authentication is through a web application. Two-factor authentication ensures that only specific and authorized individuals can access information on the server.

The web application requires two factors to be verified by the web application users before accessing the data. An example of a web application that requires two factors is a shopping cart. The user will need to supply a credit card number while filling out the online form.

Password strength:

The most common method that is used for authentication is the traditional password strength negotiation. The client software that interacts with the server authenticates itself by asking the user a secret question, like their username or password.

The server will return a challenge token that the user will have to use to verify the data they provided in response to the challenge. The reason that the user is asked to provide a password is to request a stronger password than what the server has stored.

Usually, the stronger the password is, the longer the database will be, making it more likely that an attacker will be able to crack it.

Benefits of two-factor authentication

Two-factor authentication is a method of verifying a piece of data before it is transmitted over the internet or wirelessly to the server. There are many advantages to using two-factor authentication when dealing with sensitive information.  

Layers of security:

When you add a second layer of security to something like a password, you increase the chances that your data will not be picked up by a hacker who may steal it. Also, when a hacker gains access to the data that you are trying to protect, it is oftentimes easy for them to defeat your security measures without compromising the information themselves. In most cases, a hacker has no motivation to keep their treasure if they already broke into and taken what they wanted.

Biometric authentication:

Using a unique set of fingerprints or a digital signature to prove ownership of a particular piece of data is also a great security measure. For example, a merchant can ensure that his product is authentic with a tamper-resistant chip that contains his personal fingerprint.

Should a customer wish to dispute this claim, the retailer has the right to have the chip replaced with another, more difficult one. It should be noted, however, that a chip or other form of authentication is only effective if the physical device is in use.

Passwords:

Passwords are a great way to secure a website. Unfortunately, every website is not created equally. Some websites use common password salts, meaning that they are based on a randomly generated number. This means that a hacker could create a password that is too simple to guess, thus bypassing the protection provided by salt or password.

A more secure option is using a password or access control database. You don’t necessarily need to restrict access to database users. Instead, you can configure the database that processes password changes to only allow access from those who actually have the password.

If a user attempts to log in via an insecure connection, the server will deny access until they provide the correct password. You can further prevent unauthorized access by making sure that emails are always protected and that your database is always protected against hackers on a daily basis.

Another advantage of using a password or access control database is that it allows you to ensure that all of your critical data is stored in a safe location. By using encrypted data storage, you are much less likely to be hacked into and stolen. Not only are you much less likely to be hacked into, but your data is much more likely to remain safe as long as you manage your data properly.

Saves time:

You will also save yourself a great deal of time when it comes to renewing passwords. When you are using a remote login service for your email, database, and other services, the process is quite lengthy. Often, you will need to run a series of tests in order to make sure that the new code is authentic before you can log in to your accounts. With a password or access control database, this process is shortened significantly.

Finally, when you are using a two-factor authentication system, you are increasing the amount of protection that you have. While passwords can provide some measure of protection when accessing unguarded, they are not as effective as they would be if they were used with a token.

When you use a token, anyone who is able to guess the five-digit password can gain access to the account as well, but they are not able to use the account immediately. This means that if a hacker does manage to guess the five-digit password, they will not be able to automatically gain access to any of your accounts, but if they are able to log into an account that has the token, they will be able to do little more damage.

These are only a few of the benefits of two-factor authentication. As technology continues to advance, it makes sense to make your business more secure so that your customers can feel secure about the information they are providing you.

In the end, if you can’t provide customers with a good feeling about the security of your website, then you aren’t going to be able to keep them on. Choose a strong password and a strong access control policy and you’ll be able to enjoy all of the benefits of two-factor authentication.
