Multi-factor Authentication is a Powerful Tool Against Cyberattacks

Multi-factor authentication (MFA) is one of the most powerful tools you can use in the fight against cyberattacks of various kinds. However, this tool is only effective is set up and used properly. Multi-factor works when using more than one authentication factor. That factor could be something the user knows, has or is part of what they are (like a fingerprint). The more unique combination you can use, the better protected you are.

One of the most common combinations is a username and unique password, in addition also add a message, link or code to the smartphone of the user via text messaging. Some users have their authentication factor be a pin code, an item of personal trivia (mother’s maiden name, for example), a key fob, or some type of biometric factor.

One common mistake users make when activating multi-factor authentication is by having text messaging as their second factor. That turns phone numbers into digital identity devices, which they are not designed to be. If someone loses their smartphone or has it stolen , they also lose their access to authentication. Or worst case scenario, the attacker can transfer the phone number to another person, who will now receive authentication requests.

The best way to protect your business is to ensure MFA is active within your organization. You need to mandate strong passwords and the use of password managers. Consider banning text-based authentication in favor of something more secure, such as authentication apps. With these, you’ll have a first line of defense in place.
