Multi-Factor Authentication (MFA) – An Overview

Multi-factor authentication or MFA as it is also known as has been in use for quite some time now. This technology is used extensively across the globe for a wide range of reasons such as, verification, authentication and authorisation, and as part of data storage. However, as the demand for MFA services increases, so does the need for cyber-security solutions that can protect these systems from attacks and ensure that no unauthorised person has access to the information contained within them.

Multi-factor authentication means an authentication process that requires more than just one means of authentication to authenticate the user’s identity against that of another independent source. In a nutshell, a person wanting to use a particular system is given access after giving out two or more independent pieces of data that uniquely identify them. This information which is generally stored as an algorithm, is then compared against the identity of the person requesting access. If it matches, then the person is granted access to the system.

The advent of the Internet has increased the scope and complexity of cyber security for both consumers and providers of this technology. Therefore, many organisations are now looking to use MFA techniques in order to protect their systems from hacking and the risk of the information contained within them being lost or stolen, this is particularly relevant with the introduction of GDPR and the obligations which this places on business owners.

There are a range of different cyber-security providers that provide a variety of different types of systems which provide different levels of protection to businesses and their users. In particular where sensitive information is stored such as credit card numbers increased levels of protection are normally required. These cyber-security providers often use multiple forms of authentication to ensure that the personal data is protected and cannot be hacked. The use of MFA is used by companies to provide additional levels of protection to a consumer’s sensitive personal information and ensure that all the personal data stored on the servers are kept safe from unauthorised access.

There are now many companies and organisations that employ multi-factor methods as part of their security procedures. The use of various different forms of signatures, passwords, encryption keys, encryption codes, and even different authentication tokens allows a single user to have complete control over his or her own personal data and information. This level of control and access also ensures that the security systems and network the system works on can be easily accessed by authorised users without any problems arising due to the fact that they are only granted access after they present a specific amount of personal data.

This is also the reason why multiple forms of authentication are so useful. Once a password is set up, it is practically impossible for hackers to guess the same since each individual component used in creating that password must be unique. There are many other advantages of using multiple authentication techniques as well.
