Passkey vs. Multi-Factor Authentication: Which Protects Your Payroll Data Better?

In today’s business world, cyber fraud isn’t a distant, theoretical threat; it’s already circling your doors, looking for the smallest crack in your defenses. Cybercriminals know exactly where the most valuable data lives: your payroll systems. Employee Social Security numbers. Bank account details. Private HR records. To them, it’s not “sensitive information," it’s a jackpot.
And here’s the truth no one wants to hear: it only takes one successful cyber event to devastate a small or mid-sized business. One intrusion can drain your accounts, shatter your reputation, and trigger legal nightmares that last for years. Some companies never recover.
The only question is, will you be prepared when they target you?
Two of the most powerful tools for locking down your accounts are passkeys and multi-factor authentication (MFA). While both aim to keep hackers out, they work in different ways, and understanding those differences is key to choosing the right protection for your business.
What Is a Passkey?
A passkey is a modern, password-free login method that uses cryptographic keys stored on your device (like your phone or computer). Instead of remembering a password, you verify your identity with a biometric factor (fingerprint, facial recognition) or a device PIN.
How it works:
-
You try to sign in to an account.
-
The service sends a request to your device.
-
You approve the login by unlocking your device (fingerprint, face scan, or PIN).
-
Your device sends a secure cryptographic signature (not your actual biometric data) to confirm it’s you.
Because there’s no password to steal or guess, phishing attempts are far less effective against passkeys.
What Is Multi-Factor Authentication (MFA)?
Multi-factor authentication adds an extra step beyond your username and password. You prove your identity using two or more verification factors, typically something you know (password), something you have (authenticator app, text code, hardware token), or something you are (biometric).
How it works:
-
You log in with your username and password.
-
You receive a verification request - often a one-time code in an authenticator app or text message.
-
You enter the code or approve the prompt to gain access.
Even if your password is stolen, MFA forces attackers to clear another hurdle before they can get in. NOTE: It's recommended to use authenticator apps or hardware tokens rather than SMS-based MFA, as SIM swapping is a common attack.
