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:
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.
You can learn to create a strong passphrase by clicking here.
First, head to your Two-factor authentication settings by clicking here. If the link didn’t work, you can follow these steps to navigate to these settings:
Click your profile picture in the top-right corner of the Facebook home page, then click Settings & privacy, then Settings from the menu that shows after.
On the next page, click on Accounts Centre on the left menu, then click Password and security.
Click Two-factor authentication.
This page will have a few options for you to set up MFA. You can set up more than one to further boost your account security. For this demonstration, we’ll be choosing the Authentication app.
After clicking Authentication app, a QR image will be shown, as well as a code for manually setting up your MFA. Don’t share these with anyone! Using an authenticator app on your phone, such as Microsoft Authenticator, scan the QR code.
Once you’ve scanned the QR code and added it to your app, click Continue on your computer. The next page will ask you to confirm a 6-digit code generated by your app.
Once you’ve successfully confirmed the newly generated code your Two-factor authentication is all set up!
When you next log in to Facebook on a new device, you’ll be asked to enter one of these codes before you can access your account.
We recommend further improving your account security by exploring the other Multi-Factor Authentication options and set up another method on top of the one you’ve just made.
Tap your profile picture (this may instead show as three horizontal lines ☰) in the bottom-right corner of the Facebook app (or top-right for Android phones), then tap Settings and Privacy, then tap Settings.
Tap on Accounts Centre.
Tap Password and security, then Two-factor authentication.

After tapping this option, a QR image will be shown, as well as a code for manually setting up your MFA. Do not share these with anyone! Using an authenticator app on your phone, such as Microsoft Authenticator, scan this QR code.
If your authenticator is on the same device, tap the long string of letters and numbers under the QR image to copy it on your phone, then paste it into your chosen code-generating app.
Go back to the Facebook app and tap Continue once you’ve added the code to your authenticator app. The next page will ask you to enter a 6-digit code generated by your app.
Once you’ve successfully confirmed a newly generated code from the app, your two-factor authentication is all set up!
When you next log in to Facebook on a new device, you’ll be asked to enter one of these codes before you can access your account.
