The Many Factors Of Multi-Factor Authentication

Passwords are often considered the ultimate step in keeping data secure. 

However, passwords are no longer as secure as they once were.

While passwords can stop someone casually trying to access sensitive information, they do little to prevent cyberattacks from experienced hackers.

This is where multifactor authentication comes in. 

 

What Is Multifactor Authentication?

Now that business data can be accessed anywhere, your business should require your employees to use multifactor authentication (MFA). 

Multi-factor authentication, or MFA, is another layer of security on top of the username & password that helps protect people and devices from succumbing to a cybersecurity breach.

MFA requires more than just a password to ensure the user logging in is the person that’s supposed to be there.

Also known as two-factor authentication (2FA), MFA consists of five main parts. 

Any combination of these factors can help keep data safe from cyberattack. 

Let’s take a closer look at the five factors of authentication methods and examples of what they look like.

 

Factor 1: What You Know

You may know your password.  

While it’s not the most secure factor, it’s the first line of defense. 

However, our passwords are often weak and common among other people, so they’re easy to crack and allow hackers to gain access.

Create a strong password by creating a passphrase from an acronym that is unique to you. 

Passphrases should include capital letters, numbers, and symbols in order to prevent the average person from getting into sensitive data. 

This is the crucial first step every business should use to keep their data and their clients’ data safe.

 

Factor 2: What You Have

You have the security question you selected when creating your account with a particular service. 

Banking sites are a great example of requiring security questions. 

They ask you things like what your mother’s maiden name was or the name of your early childhood pet. 

The question asked shouldn’t be commonly known amongst your colleagues or peers, and should not be easily cross-referenced with other public information, such as street address. 

Other examples of this type of authentication include:

  1. Authentication apps, such as Google Authenticator or Authy
  2. Time-based, one-time passwords (OTP) that show up in text messages or emails and are only valid for minutes at a time
  3. Push notifications from an app. 

This is one of the easiest factors for an organization to employ beyond a password alone.

 

Factor 3: Who You Are

You can use your own biometrics to aid in the authentication process. 

This means that some part of your physical being is needed for the authentication process—fingerprints or facial identification are two great examples of this for smartphones. 

While biometric authentication is incredibly safe and hard to break, implementing these types of authenticators for some protections may be cost-prohibitive. 

 

Factor 4: Where You Are

You—and your device—are always somewhere.

Some products and services track the most common login points for information and send a warning if the account is logged in from a different place. 

This is most common with tech services such as Google, warning its users when their email has been logged into from a new device. 

This is an excellent service for businesses to use, especially if they give their employees work devices to use and as more companies have implemented a remote workforce. 

If someone has logged into an account from a device that was not logged by the company, it could be an instant giveaway that the login may not be legitimate.

 

Factor 5: What You Do

This is a lesser-used form of authentication, but serves as another secure step. 

When you log in to a product or service, this factor requires you to perform a tactile movement. 

It could also be a series of swipes or taps in a pattern known only to you, similar to the lock screen on some mobile phones. 

The biggest downside with this is that, like with passwords, most users pick repeated patterns that make it easier for hackers to figure out. 

A business looking to use this feature should give their employees specific, randomized motions to make it safer.

Overall, multifactor authentication is required in some industries, while in others, implementation is optional.

As cybersecurity incidents increase each year, MFA is a common recommendation we make regardless of the industry you’re in. 

Enabling MFA is a strong defense against your personal or business information bubbling up in a breach.
