Two-Factor Authentication: What It Is and Why You Need It

Once upon a time, a simple login and password was sufficient to keep your valuable business and client data safe. But, just as technology has become smarter and more efficient, so have cybercriminals; always on the lookout for ways to target and victimize small to medium-sized businesses (SMBs) just like yours.

Enter two-factor authentication: an essential step for improving your online security and protecting your organization from malicious hackers.

What is Two-Factor Authentication?

Often referred to as 2FA, dual-factor or two-step verification, this online security process requires users to identify themselves via two different authentication methods. Instead of depending on single-factor authentication (SFA), such as a lone password, 2FA requires both a password and secondary form of verification - i.e. and inherent factor (fingerprint, eye scan or other form of biometric), or physical token (key card, mobile app or other token device).

Types of Authentication

In addition to the traditional passwords, physical tokens and biometrics mentioned above, other authentication factors may include:

  • Location Factor: Access is based on the user’s location. Tracked via IP addresses, GPS data, or other form of location intelligence, authentication attempts made outside the designated area will be rejected.
  • Time Factor: Authentication is granted within a specific timeframe only. Any attempts made outside the established timeframe will be rejected.

 

Keep in mind, using the same two factors (i.e. two passwords) doesn’t count as two-factor authentication. True 2FA is based on two varying factors, such as a password and location factor.

How Does Two-Factor Authentication Work?

Two-Factor authentication can be broken down into three simple steps:

  1. After being prompted to log in, the user inputs some form of knowledge-based authentication factor(typically user name and password).
  2. The user is then prompted to provide secondary authentication. This usually comes in the form of a physical token, such as a 2FA mobile app (i.e. the Cisco Duo, more on that below).
  3. The user enters a one-time code, generated during the secondary authentication process.

Once this code is entered, the user is authenticated and can now access the application or website. 

Why Two-Factor Authentication is Essential For SMBs

Canadian small businesses suffering a data breach were down for an average of 59 hours at a cost of $1.1 million in a single year. If you hope to avoid becoming another small business statistic, you need to verify people are who they say they are.

Simple, scalable security platforms such as Cisco Duo can help SMBs protect their clients, employees and data by providing affordable 2FA solutions. Effective and secure the Cisco Duo, in particular, can be easily integrated to protect every point of access (on-location, cloud and web-based applications). An all-in-one platform, Duo allows you to verify user identities, assess the health of your devices, set adaptive access policies and much more.
