How to set up Multi-Factor Authentication and why you need it

How to set up Multi-Factor Authentication and why you need it

One of the best ways to protect yourself online is also one of the simplest: setting up Multi-Factor Authentication (MFA) for your accounts.  

What is MFA? 

Multi-Factor Authentication, or MFA, is a security step allowing users to verify their identity before accessing sensitive information.  

Some examples of MFA include: 

  • ‘Biometric’ security, such as using your fingerprint, Face ID, or voice recognition. 

  • Authenticator codes, which can be obtained from a third-party code generator app or physical token. 

  • Two-factor PIN codes sent via email. 

It’s much harder for bad actors to gain access to an account with MFA than it is to learn your password. This makes MFA a powerful security tool, and has been widely adopted by most online platforms and services (including Aussie). 

You might’ve heard of Two-Factor Authentication, or 2FA, which is technically a form of MFA. However, they are different – 2FA only uses 2 authentication steps, while MFA uses 2 steps at a minimum.  

 

Where should I use MFA? 

Wherever you possibly can. 

If MFA isn’t available for an account, it’s best to make sure it has its own strong passphrase that isn’t used anywhere else. This way, if the worst happens and your password is compromised, it cannot be used to access any of your other online accounts.
