Beat MFA Fatigue

We all get tired—whether it’s from a long day at work, a tough workout, or even binge-streaming on TV.  But there’s another kind of exhaustion you might not know about:  MFA fatigue.  It’s leveraged by cybercriminals to try and break into your accounts.

What Is MFA Fatigue?

MFA stands for Multi-Factor Authentication.  It’s that extra step you take when logging in—like entering a code sent to your phone or tapping “approve” on an app.  It’s a terrific way to keep your accounts secure.

Scammers have figured out how to turn MFA against you. They’ll hit you with a flood of prompts—email, text, app notifications—you name it.  The goal?  To wear you down and confuse you into clicking “approve” without thinking.  And once that happens, they’re in.  Tactics include:

  • Fake Support Messages: After spamming you with prompts, scammers might text you pretending to be from IT or customer support.  They’ll say something like, “We noticed suspicious activity.  Please approve the login to secure your account.”  Sounds official, right?  Don’t fall for it!
  • Late-Night Calls: Another sneaky move is calling you in the middle of the night when you’re half-asleep.  They’ll ask you to approve a login, hoping you’ll do it without thinking.  It’s social engineering at its finest.


To avoid MFA fatigue:

  • Don’t approve login requests you didn’t start—trust your instinct.
  • Unexpected MFA prompts? Change your password immediately
  • Use strong, unique passwords. A password manager makes it easy.
  • Check with others if you share an account and get a surprise prompt.
  • Turn on number matching to avoid accidental approvals.
  • Enable login alerts to catch suspicious activity early.


MFA is still one of the best ways to protect your accounts—but only if you stay alert.  Don’t let scammers wear you down.  Stay sharp, stay safe, and don’t let MFA fatigue win.
