Everything You Need to Know About Multi-Factor Authentication (MFA) 172f5k

For a long time, s have been a trusted method of securing data. However, as cyberattacks become increasingly sophisticated, having a strong backup is not enough.

In fact, statistics also revealed that poor s caused 81% of data breaches in 2024. Therefore, an added layer of security is necessary.

This is where multi-factor authentication tools become indispensable. They are excellent at preventing cyber attacks and ensuring robust data security. Let’s understand MFA and everything you need to know about it.

What is Multi-Factor Authentication? 3n1853

Multi-factor authentication is a validation method or way used to a person’s identity, and multi-factor authentication tools help with this.

Like having a door and safety door in your home for dual security, multi-factor authentication involves two steps of verification. Your usual is paired with a secondary authentication step, which adds an additional layer of against unauthorised access.

There are several forms of multi-factor authentication methods, like one-time s (OTPs), biometric scans, security tokens, etc.

How Does Multi-Factor Authentication on Devices Work? 4t536b

Multi-factor authentication works by adding two or more forms of authentication for access to an application or device. Unlike traditional authentication, which uses a single form of authentication, multi-factor authentication adds a layer of verification. You usually go through these steps-

Entering name and 2h1r1q

It is your usual first layer of authentication, which helps to using something you know.

Added Verification 2u2u5z

Once you have the first layer of authentication, you need an added layer of verification to identify yourself using something you have or something you are. This can be done using a code on your alternate device or a biometric scan like your fingerprints.

If you have successfully completed the required authentication, you will be given authorisation for the required device or .

Types of Multi-Factor Authentication 5c2x1t

SMS Based 1v3z4z

SMS-based multi-factor authentication for a device or application involves receiving an OTP on your ed mobile number. You need to enter the OTP followed by your to get into your .

This is the easiest form and widely used multi-factor authentication. However, the only drawbacks of MFA are interception by an attacker or access through the device by someone else.

Time-Based OTP 4o4r40

Time-based OTP is a 30-second multi-factor authentication application mechanism generated using an app on the ’s mobile or dedicated hardware token. As above, you enter OTP, which is followed by a to gain access. This form is considered more secure as the OTP is created locally, and there is no internet involvement.

Biometric 25j49

Biometric authentication is based on your ’s physical characteristics. This can take several forms, such as facial recognition, fingerprint, etc.

This form of multi-factor authentication is more secure than the traditional form, as physical characters are not easy to replicate.

Push Button j4r3w

With the push-button multi-factor authentication on the device, a notification is sent to s’ mobiles telling them to authenticate the request. Once the approves or denies the request, access will be given accordingly. This form requires s to give confirmation to offer access, which makes it very secure.

With multi-factor authentication, you add additional layers of security to keep your device, application or safer. Depending on your infrastructural security needs, you can use two-factor authentication in several forms and combinations.

The right form of multi-factor authentication not only ensures security but automatically lowers the impact of phishing attacks. It also assures compliance with regulatory requirements and peace of mind. So, enjoy an additional security layer to your infrastructure with multi-factor authentication and strengthen your security like never before.
