Interscale Content Hub – In today’s world, where cyber threats are getting more and more sophisticated, MFA is one of the traditional cybersecurity approaches that still works well. But what is multi factor authentication, actually?
Basically, MFA is an extra layer of security that requires users to provide a few different forms of verification to access an account or system.
MFA makes it harder for hackers to get into your account if they get one piece of information wrong. It’s like having a bunch of locks on your door. If one lock is broken, it’s not easy to get in.
So let’s talk more about MFA here.
Definition of Multi-Factor Authentication
Multi-factor authentication (MFA) is a security method that requires users to provide multiple forms of identification to access a system.
By requiring multiple authentication factors, MFA reduces the risk of unauthorized access and significantly improves overall security posture.
According to JumpCloud in “State of IT 2024: The Rise of AI, Economic Uncertainty, and Evolving Security Threat,” 83% of organizations use MFA to secure their IT resources. This shows how widely it’s used and how effective it is.
The Importance of MFA
MFA is becoming hot right now as a way to beef up an organization’s security.
MFA makes it much harder for attackers to gain unauthorized access by requiring multiple verification steps.
Google’s research in “New research: How effective is basic account hygiene at preventing hijacking,” showed that adding a recovery phone number can block up to 100% of automated bots, 99% of bulk phishing attacks, and 66% of targeted attacks. This is proof that basic account hygiene is an effective way to prevent hijacking.
The financial implications of data breaches are significant. The IBM “Cost of a Data Breach Report 2023” says that the average cost of a data breach in 2022 was $4.35 million.
MFA can help organizations reduce the risk of such breaches, which means they’ll have less to lose if a breach does happen.
Deploying MFA helps businesses protect sensitive information and stay in line with data protection regulations like GDPR and PIPEDA.

How MFA Works
Multi-factor authentication (MFA) is a great way to make sure your data is safe. It requires users to verify their identity through multiple methods.
The process starts with the user logging in with their username and password, which is the first factor—something they know.
Then, the system asks the user to do one more thing to verify their identity, like entering a code sent to their mobile device or doing a fingerprint scan. This second factor adds an extra layer of security.
Even if someone gets hold of your password, they won’t be able to access your account without the second factor.
For example, in the Australia Tuition Protection Service (TPS) Online system, users have to provide both a password and a one-time code generated by an authentication app or sent via email.
This method shows that using MFA can really cut down on the risk of unauthorized access by requiring multiple forms of authentication.
This multi-layered security approach means that if one factor is compromised, the other remains secure, making it much harder for attackers to gain access to sensitive information.
In practice, once the user has provided both factors, they can access the system.
This approach effectively deals with the risks of stolen credentials, as shown by the use of MFA in TPS Online to protect users’ accounts and information.
Types of Authentication Factors
Multi-factor authentication (MFA) uses a few different types of security measures to make sure that only the right people can access your data.
These are usually split into three main categories: knowledge, possession, and inherence factors.
The most familiar form of authentication is the knowledge factor, which relies on something the user knows.
The most common example is a password, but it can also include PINs or answers to security questions.
While they’re easy to set up, knowledge factors can be vulnerable to guessing, phishing attacks, or data breaches.
With possession factors, it’s something the user has on them.
This could be a one-time password (OTP) sent via SMS or email, a code generated by a mobile authenticator app like Google Authenticator, or a hardware token like a YubiKey.
With possession factors, you’ve got a solid layer of security because they’re generally harder to steal or replicate than knowledge factors.
Inherence factors are based on something the user is, often called “biometrics.” This includes things like fingerprints, facial recognition, or voice recognition.
Inherence factors are unique to each individual, making them a reliable way to authenticate. However, they can be more complex to implement and raise privacy concerns.
Please remember each type of authentication factor offers a different level of security and user experience.
For instance, one-time passwords (OTPs) add an extra layer of protection beyond just a password. They’re temporary and expire after a single use.
Push notifications sent to a user’s device are a great way to provide a user-friendly experience while still being relatively secure.
Security keys, like the YubiKey, are seen as one of the most secure options out there thanks to their physical nature and advanced cryptographic capabilities.
While biometrics are convenient and secure, they can raise concerns about privacy and data storage.
So, by combining two or more of these factors, MFA makes accounts and systems much more secure.
Even if one factor is compromised, the attacker still needs to overcome the other factors to gain unauthorized access.

How to Implement Multi-Factor Authentication
First, take a look at what you need to protect and make sure you’ve got the right level of security in place. This assessment helps you zero in on the most sensitive areas of your organization.
Next, choose the right authentication factors for your organization and users.
Some common factors are knowledge-based, like passwords, possession-based, like one-time passwords (OTPs) generated by mobile apps or hardware tokens, and inherence-based, like fingerprints or facial recognition.
The next thing to do is integrate MFA solutions. Make sure you choose tools that integrate seamlessly with your existing systems.
Some popular solutions are Microsoft Azure MFA, Google Authenticator, and hardware tokens like YubiKey.
For instance, Microsoft 365 lets admins enable MFA through security defaults or conditional access policies, which gives you a solid security framework.
And don’t forget to educate your users on the importance of MFA and how to use it effectively.
And don’t forget to keep an eye on how well MFA is working and make any necessary adjustments. This also means doing regular audits of your MFA implementation to make sure it keeps up with changing security needs.
For instance, you can start with admin accounts to test out MFA before rolling it out to everyone. This makes it easier to make the switch.
