What is MFA?
MFA is an added layer of security designed to confirm your identity when logging into an online service or account. This helps protect your accounts from being compromised by cyber criminals. MFA requires that you enter additional information to gain access to your account. It’s also referred to as ‘two-factor authentication’ or ‘2FA’.
Why MFA is important
Using MFA makes it harder for cyber criminals to break into your account than if you only use a password. With MFA turned on, if your account is compromised and the criminal has your password, they will need to enter additional information that only you can provide.
Online accounts such as banking, social media and email can contain a lot of valuable information about you. Information that could be accessed includes:
- Personal identifiable information
- Banking details
- Employment details
- Information from government agencies such as Medicare or myGov
- Personal photos and messages.
If a cyber-criminal gained access to any of your accounts, they could:
- Sell your data on the black market. This could include credit card numbers, names, addresses, emails, date of birth and so on.
- Gain access to social media accounts by resetting your password.
- Send phishing emails to your contact list. These could trick your friends and family to give out personal information or install malware onto their devices.
- Send fraudulent email requests for payment. Learn how to avoid email scams.
Different types of authentication
One-factor authentication is something that only you know, like your password or PIN. Systems that use one-factor authentication only require a username (such as an email address) and a password to access them.
Two-factor authentication is something you know (password), plus something you have. Systems that use two-factor authentication require a username and a password, plus a one-time password or code (sent to your mobile phone, for example) to access them.
Three-factor authentication is something you know, plus something you have, plus something you are (a biometric input, such as a fingerprint scan to unlock your phone). Systems that use three-factor authentication require a username and a password, a one-time password or code, and some other unique biometric that identifies you.
