Why Multifactor Authentication Is Essential for Modern Cyber Security

February 25, 2019 4 min read

In a world where cyber threats continue to evolve at alarming speed, protecting user identities has become one of the most important elements of organisational security. One simple yet highly effective measure stands out above the rest: Multifactor Authentication (MFA), also known as Two Factor Authentication (2FA).

MFA adds an extra layer of security to your login process by requiring more than just a username and password. At a time when passwords are frequently stolen, guessed, leaked, or compromised, MFA is no longer optional — it’s essential.

What Is Multifactor Authentication?

Multifactor Authentication requires users to present two or more independent verification factors to prove their identity. These typically include:

  • Something you have – a smartphone, ID card, or authenticator app
  • Something you know – a password, PIN, or memorable word
  • Something you are – biometrics such as a fingerprint or face scan

Most organisations use a combination of two factors, such as a password plus a verification code generated by an authentication app.By requiring more than one credential type, MFA makes it significantly harder for cybercriminals to gain unauthorised access, even if your password is compromised.

Why MFA Matters: The Aim and the Threat Landscape

The core purpose of MFA is simple: to prevent unauthorised access to accounts, devices, and networks. With traditional password‑only login methods, cybercriminals need just one thing to break in.

Unfortunately:

  • Usernames are often email addresses — publicly available
  • Passwords are frequently stored in databases
  • Data breaches happen every day
  • Many passwords are still weak or reused across accounts

We’ve seen major global companies suffer large‑scale data breaches in recent years, demonstrating how vulnerable password‑only security really is.

MFA creates additional barriers that significantly reduce the likelihood of an attacker successfully accessing an account.

What About Biometric Authentication?

Biometric authentication — fingerprints, facial recognition or voice ID — is becoming more common. While secure, biometrics are not perfect and raise unique concerns, such as:

  • The potential for cloning fingerprints
  • The impossibility of changing a stolen biometric (unlike a password)

Biometrics alone can still be a single point of failure. But when combined with a second factor in an MFA setup, they become far more secure, dramatically reducing the risk of compromise.

Introducing MFA in the Workplace

As MFA becomes more widely used in personal services like online banking, user resistance is reducing. However, implementing MFA in the workplace still requires careful planning and communication.

1. Staff Awareness & Training
Explain why MFA is needed — and more importantly, what could happen if passwords are compromised and MFA is not in place. When employees understand the risks, they are more likely to support the rollout.

2. Change Management
MFA affects daily routines, including the morning login process. Upfront communication, training, and hands‑on support are crucial to ensure a smooth transition.

3. Smart Implementation Design
One size does not fit all. MFA platforms, including those in Microsoft 365, can be configured intelligently.

For example:

  • MFA can be disabled within the secure head office (where physical security controls exist)
  • MFA can be enforced only when staff are working remotely or off-site
  • Users with smartphones can use a free authenticator app
  • Users without smartphones can receive one-time codes via SMS or even a landline phone call

This flexibility removes barriers and ensures MFA is accessible for everyone.
