MFA Isn't Enough Anymore: Why It's Time for Passkeys

MFA worked wonders, but it is showing its limits

Turning on two-factor authentication has long been the best advice you could give. And it still holds: an account protected by MFA is far safer than one protected by a password alone. The problem is that attackers have adapted.

How MFA gets bypassed

Real-time code theft

A fake site mimics your login page. You enter your password, then the code you received by text. The attacker grabs both and logs in as you within the second. A one-time code does not protect you if you type it on the wrong site.

Notification fatigue

Some attacks bombard the user with approval requests until they finally tap "Approve" out of sheer annoyance. It is simple, and it works far too often.

Passkeys change the game

A passkey replaces the password with a pair of cryptographic keys tied to your device. In practice, you sign in with your fingerprint, your face or your device PIN.

What makes it so strong: the passkey is bound to the real site. It simply refuses to work on a fake page. Classic phishing stops working, because there is no longer a code to steal.

How to start the transition

  • Begin with critical accounts: email, administration, finance.

  • Enable passkeys in Microsoft 365 or Google Workspace, which already support them.

  • Keep a backup method during the transition, then phase out the old ones.

  • Support your employees: the first passkey sign-in feels new, but it is simpler afterward.
  • A step toward passwordless authentication

    Passkeys are not a passing trend. The major providers are pushing them because they close the door on an entire category of attacks. Adopting this approach now puts you ahead of the threat.
