Multi-Factor Authentication: Why’s it important?

Multi-factor authentication, or MFA is a security measure used to ensure that no third party can gain access to an account.

MFA requires a user to provide two or more verification factors to access the account.

We see 2-factor authentication or 2FA the most.

2FA is essentially the same as MFA but it locks the number of factors to only two.

You will usually see or use MFA in the form of one-time passwords.

These are normally 6-digit codes; however, they could be 4-8 digits long.

When being asked to set up 2FA/MFA, you are usually given a few different options, depending on what site or account it is.

When you are trying to access it, you will be able to receive a 4–8-digit long code via email, text, and sometimes a phone call.

However, the previously mentioned methods are being pushed to the side by authenticator apps.

Google and Microsoft both have authenticator apps for mobile devices, that will randomly generate 6-digit codes so you can quickly find and input this to gain access to your account.

This provides an extra layer of security as a third party will not only need your original account password but also your mobile device and the password for the device. 

Other factors of authentication are passwords or pins, and newer biometrics like Face ID, fingerprints, and so on.

Biometric authentication methods are particularly helpful as they are unique to you and extremely difficult for third parties to get through without having the actual password.

You also have possession-based authentication methods including security keys, Fobs, USB devices, and one-time passwords generated via smartphone apps or sent through text.

This will help keep your accounts secure as there is an extra wall of passwords, and a third party would have to get the physical item from you.

A lesser-used form of authentication is location-based MFA.

A user’s IP address will be saved as their location can be found using this.

When someone tries to access the account, their IP address must match to gain access.

This is quite an extreme method which is why it isn’t used too often. 

MFA is being enforced more and more now. It is an extremely useful way to keep your accounts and data safe.

Setting up MFA for accounts is simple and takes only a few minutes.

Although it is a simple precaution we highly recommend you consider activating and setting up MFA on your accounts to ensure only you can access them.
