MFA refers to multi-factor authentication.
MFA forms additional layers of security by ensuring multiple forms of identification are used to access an account or system. MFA typically uses a combination of something you know (like a password), something you have (like a smart card or token), and something you are (like biometric data).
2FA refers to two-factor authentication.
2FA is similar to MFA, however typically uses a combination of something you know (like a password) and something you have (like a code sent to your phone) to access an account or system.
Whilst both MFA and 2FA are used to add an extra layer or layers of security at login, MFA typically involves a three or more-factor authentication, while 2FA only requires two-factor authentication.
Financial institutions and other high-risk companies typically use a 2FA when logging into online banking by using a one-time code sent to your phone or email after entering an account username and password. This extra step adds a layer of security to protect accounts from unauthorised access.
Typically, a 2FA access uses an initial password, and then requires a second form of identification, such as a fingerprint or a code sent to your mobile device.
MFA must be the better option. Extra layers of security help prevent hacking and identity theft.
MFA significantly reduces the risk of unauthorised access and protects against password-related attacks such as phishing and brute-force attacks. By requiring additional information, MFA makes it much more difficult for hackers to access sensitive information or systems. This is a simple and effective way to enhance security and protect against cyber threats.
Where to from here?
You have probably already started to notice that many accounts and platforms now include an option to enable 2FA or MFA. Wherever this option is available, it is a good idea to opt in and set up this extra layer of protection.
Where you are using software that does not include this option, you may want to consider what alternatives are available, as this is one of the most effective ways to protect your valuable information and accounts against unauthorised access.
Remember though, 2FA and MFA will only work effectively if you do your part and make the ‘password factor’ a hacker's nightmare. If you hate passwords like most of us do, not changing your password for many months opens the door to hackers. Hackers love lazy people who won't change their password and use non-complex options.
