All about multi-factor authentication

Multi-factor authentication (MFA) is an easy way to add an extra layer of protection to your online accounts. It requires you prove in 2 or more ways that you’re the real owner of an online account.

These ways of proving an account is really yours are called ‘authentication factors’. They are designed to make it harder for hackers (cybercriminals) to get into your account.

For example, using a password alone is called ‘single factor authentication’. This is because you’re using only one type of authentication factor to log into your online accounts.

The problem is that passwords can be guessed or stolen.

MFA is when you use your password and at least one other authentication factor to prove you’re the account owner. Other authentication factors could be passphrases, a fingerprint on your phone, or codes sent to your phone number or email address.

When to set up MFA

It is important to turn on MFA for important online accounts, such as:

  • user and email accounts
  • financial services
  • government services
  • shopping websites that save your payment details.

Be scam savvy

Scams take many forms and can be hard to spot. New scams pop up all the time and can affect anyone.

Scamwatch, led by the National Anti-Scam Centre, encourages all Australians to:

  • Stop: don’t give money or your information to anyone if you’re unsure
  • Check: ask yourself if the message, call or website link is fake
