What is Multi-Factor Authentication?

Cybercrime is steadily increasing. Cybercriminals are exploiting the vast and ever-expanding realm of the internet for their own gains. But how can we safeguard our valuable data from these online threats? Is there a solution that's accessible to both individuals and organizations?Yes, there is a solution that goes by the name of two-factor authentication (2FA) or multi-factor authentication (MFA). MFA adds another layer of security to login practices, making it even more difficult for cybercriminals to access accounts and systems.For over 25 years, WEBIT Services has guided clients toward their IT objectives and fortified their systems with various cybersecurity tools and practices.By reading this article, you will learn why security experts recommend utilizing MFA, how it works, and the different kinds of available MFA systems.

Why Are Passwords No Longer Sufficient?

Relying solely on passwords for data protection is no longer adequate.Cybercriminals use various tactics to exploit passwords, such as brute force attacks, phishing emails, and social engineering. If they succeed in obtaining one password, and you've used the same password across multiple accounts, all your accounts become vulnerable.For a password to offer remote security, it should meet these criteria:

  1. It should be a random mix of letters, numbers, and special characters.
  2. At a minimum, it should be 12 characters long.
  3. Each password should be unique for every account.
  4. Passwords should be updated every 90 days.
  5. Ideally, a passphrase, as recommended by the FBI.

Even with these precautions, cybercriminals can still breach accounts. Therefore, we must implement additional safeguards to stay ahead of these threats. This brings us to MFA.

Understanding Multi-Factor Authentication

MFA adds an extra layer of security by involving an external program.After entering your password, you must provide a randomly generated, time-sensitive code to access a website or account. This code can comprise numbers, letters, or a combination of both.MFA is not a one-size-fits-all solution; there are generally three types available:

  1. SMS-Based MFA: A verification code is sent to your mobile phone via text message, which you must enter to log in. This is cost-effective and widely used but can be vulnerable if someone gains access to your phone number or device.
  2. App-Based MFA: You can download an app like Google Authenticator or Microsoft Authenticator, which generates account login codes. It's free and popular, but it can be compromised if your phone is stolen or compromised.
  3. Token-Based MFA: This method generates codes on a physical device called a "token" linked to a specific account or website. Tokens must be purchased individually, making them more expensive but highly secure.

Consider the options carefully to choose the suitable MFA for your needs and budget.

How MFA Enhances Data Security

As mentioned, MFA adds an extra layer of protection.While your password acts as a lock on your account's door, MFA serves as the deadbolt. These codes are challenging to hack, given their randomness and time sensitivity. Even if a cybercriminal guesses the code, they must do so within the limited timeframe to use it. Once the time expires, the code becomes useless.A cybercriminal can get hold of an MFA code if the account holder directly provides it or is tricked into revealing it through a phishing scam. Therefore, never share your MFA code.MFA systems are highly effective at thwarting hacking attempts, and many cyber insurance providers now require it, as it significantly reduces data breach risk, lowering financial risk for businesses and insurers.

The Challenges of Using MFA

MFA adds an extra step to the login process, requiring a few more seconds to generate and enter the access code. However, these additional seconds are a small price to pay for the increased security it offers. Unless you're a cybercriminal, MFA is nothing but a benefit.

Next Steps for Implementing MFA

Now that you're acquainted with the different types of two-factor authentication and their added protection, you might be eager to adopt this practice in your organization. Here's how to get started:

  1. Determine which 2FA system suits your needs and budget.
  2. Consult your IT provider or in-house IT team to integrate MFA into your existing systems.

Starting with MFA need not be daunting; you don't have to do it alone.
