All things Multi-Factor Authentication (MFA): A data-backed guide

Ever juggled a million online accounts among work emails, social media, banking apps, and a myriad of shopping sites? What seems to be a recuperated battle for keeping track of logins is always there. And, of course, security—a weak password and your whole digital life is laid open.

Now comes multi factor authentication solutions. It's sort of adding another lock to your online door for added security on top of your password. But here comes the thing: many people do not want to enable many multi factor authentication solutions because it would, in their opinion, make it a headache to log in.

Is that the case? Let's dive into the data and see if the extra step of multi factor authentication solutions is worth the security boost.

Before diving into multi factor authentication solutions, let's face reality: passwords. A Verizon report depicts a grim picture—81% of data breaches involve weak or stolen passwords! Here's why passwords alone are simply not enough:

Weak Passwords: We've all been there – birthdays, the name of your cat, the ever-popular "123456." These jaded passwords ease the hacker's work of guessing or cracking with automated tools.

Phishing Attacks: Emails and websites masquerading as real entities will dupe people to give away their passwords. Indeed, even the most cautious individual could have fallen prey to a phishing attack that was really well-executed.

Password Reuse: It provides a domino effect. That is, using the same password across all accounts so that if one gets compromised, hackers can easily access all other accounts with that same password.

Understanding MFA: The Extra Step That Packs a Punch

Multi Factor Authentication solutions will boost the security of your logins. Unlike single-factor authentication, which relies on a password only, multi-factor uses another factor to help identify you. That second factor might be:

Authenticator App

The mini security guard in your phone! These apps create unique codes at the end to be entered during login, paired with your password.

Biometric Authentication

This involves fingerprint scanners or facial recognition systems that will identify you based on your unique physical characteristics. No more hassles of remembering complicated passwords!

Security Key

It is a physical device that acts as a digital key. Plugin to a computer or use it wirelessly, and this would add another layer of actual security by confirming the login attempts.

While this extra step of MFA may seem to be a barrier initially, the security benefits far outweigh any perceived inconvenience. Let's look at what the data says regarding the actual impact of multi factor authentication solutions on login times.

The Data Debunks the Myth: MFA and Login Speed

One of the significant concerns was supposedly going to be the perceived slowdown in login times with multi factor authentication solutions. But is this really an issue, or is it more of a myth? Let's use some data-driven insights to clear up this myth.

Independent studies by leading organizations indicate that there is almost zero overhead on login times with MFA turned on.

According to a study by Microsoft Azure AD, conducted with billions of logins, the average login time increased by only 0.13 seconds after MFA was turned on.

In the same light, analysis from real-world login data by Duo Security revealed that, generally, MFA takes an extra 3.3 seconds for login.

These results indicate that the extra seconds needed for MFA are basically infinitesimal within the context of the security that it adds. Really, in the bigger picture, a few extra seconds are hardly anything to pay for your online accounts to be protected.
