Finding the right Multi-Factor Authentication solution for your company can be a daunting experience. When researching various providers online, be prepared to discover many conflicting perspectives on fraud prevention and user experience (UX). Purchase the wrong solution and you could be on the hook for a spike in fraud. To help you navigate the MFA marketplace with confidence and select the right solution for you, we answered the top three most common (and important) questions we get from clients.

What is Multi-Factor Authentication?

Let’s cover the basics first. Many customers have heard about MFA but don’t know exactly what the term implies. Let’s go to the source. The National Institute of Standards and Technology (NIST) defines Multi-Factor Authentication as: “Authentication using two or more factors to achieve authentication. Factors include:

  1. Something you know: Think passwords and PINs. 
  2. Something you have: Think FIDO keys or phone.
  3. Something you are: This is also called inherence. Think of biometric data like fingerprints, face scans, and voice recognition.

While the MFA framework is not new (even the ATM requires you to swipe your debit card and enter your PIN before letting you withdraw cash), it is increasingly common online. Today, for instance, creating a social media account, signing into your email from an unfamiliar computer, and ordering food online will most likely require you to undergo an MFA process. The reason? MFA is a powerful tool to prevent fraud.

What is the role of one-time passcodes (OTPs) in a modern MFA solution?

Today, the one-time password (OTP) is a commonly used credential that verifies a user’s identity using something you have (a phone). At Prove, we call this ‘running a possession check.’


Here’s how it works from the user’s perspective: When a customer first creates an account, they enter their phone number. Later, when they log in or complete a high-risk transaction, a series of random digits is texted to their phone. To continue, they must enter the digits that were texted to them. You probably have first-hand experience with OTPs if you’ve ever logged into your Amazon account from a new computer or opened your banking app on your phone.


Although OTPs are extremely popular with consumers and used widely across industries, one-time passcodes (OTPs) are a controversial topic in the digital identity space because of their security vulnerabilities. While almost every fraud expert would agree that old-school OTPs have significant security vulnerabilities (SIM swaps), the question is what to do next. Some experts believe that OTPs should be fortified to protect against SIM swaps while others think it is best to pivot to new technologies altogether. In truth, both parties are probably right. The long-term goal should be to pivot to better authentication technologies while the short-term goal should be to fortify and improve existing security technologies that are already popular with consumers. 


Check out the MFA Buyer’s Guide for a comprehensive list of ways fraudsters can steal OTPs and how you can stop them.


What should we look for in new solutions?

When investing in a digital identity solution, it’s critical to prioritize user experience (UX). In today’s economy, customers are short on time and want identity verification to be a painless experience. In fact, according to the 2022 Passwords & Authentication Consumer Trends Report:

  • 62% of U.S. consumers said they’d abandon trying to log into an account after just three failed password attempts
  • 51% would switch brands as a result of slow identity verification
  • 34% would switch providers if they’re unable to log into their accounts easily. 

Because time is a priceless commodity in today’s fast-paced world, speed is critical. Prove’s Multi-Factor Authentication (MFA) Buyer’s Guide: How to Upgrade to True MFA provides actionable tips on how to improve UX and accelerate authentication on the back-end without breaking the bank.
