The Importance of Two-Factor Authentication

ARK Systems Two-Factor Authentication

Two-factor authentication strengthens the security of your network and accounts to prevent unauthorized access.

Cybersecurity is just as important as physical security, especially in modern times, where hackers keep getting better and more efficient, but online security struggles to keep up. Passwords are well-known for being a weak security measure, but it’s also the most accessible method for cybersecurity meant to keep unauthorized users out of your sensitive online accounts. For individuals, this can protect online banking and shopping accounts. For businesses, cybersecurity often focuses on preventing access to sensitive administration, security, and data systems.

What is Two-Factor Authentication?

Two-factor authentication, also known as 2FA, adds an extra layer of security on top of your passwords. This can be the deciding factor when it comes to keeping hackers out of your network and away from sensitive data. Most people are likely familiar with two-factor authentication, but there are several ways to implement it. The best method depends greatly on the systems being protected and who needs to be able to access them.


One of the most common and widely used methods is through codes sent to your email or mobile phone. These are one-time authentication codes that only you can access to keep the account secure and ensure no hackers are capable of infiltrating your network or accounts.

Security Questions

Another common form of authentication is through security questions—knowledge only you have. These questions can be anything from the street you grew up on, your mother’s middle name, or your first pet’s name. The idea behind these questions is that it is information only you, or those you trust, will know. Be careful with which questions you choose in case there are people in your life that you don’t trust who know those answers.

Security Keys

A security key is a small USB with an NFC tag that gives it an individual identity. These can be tied to highly sensitive accounts, so every login requires the key. Requiring a physical device is a strong method of security that makes vulnerable accounts and networks significantly more secure.


Biometrics most commonly scan fingerprints, but they can also be utilized to identify voice patterns are perform iris scans. These are best used for physical security, preventing unauthorized access into sensitive areas of high-security facilities such as government buildings.

Why is Two-Factor Authentication Important?

Passwords simply do not protect accounts and networks well enough. For businesses and facilities, there are often databases of sensitive employee and customer information that need to be protected, as well as security systems that are integrated and monitored through online and mobile access. Without two-factor authentication, information and security access are always at risk. It’s never a bad idea to discuss your options with a security professional and decide which types of two-factor authentication can protect your network and accounts.
