MFA: Strong Protection—But Not Perfect 

Multi-Factor Authentication (MFA) is one of the best ways to protect your accounts. But like every security tool, it’s only as strong as how we use it. 

Enter the MFA Fatigue Attack—a tactic that preys on distraction, habit, and exhaustion. 

What is an MFA Fatigue Attack? 

In an MFA fatigue attack, a cybercriminal attempts to log into your account repeatedly, triggering a flood of MFA prompts—usually on your phone or smartwatch. 

The goal? 
You get annoyed, distracted or overwhelmed… and eventually hit “Approve” just to make the pop-ups stop. 

And with that, the attacker is in. 

Why MFA Fatigue Works 

We’ve all been there—trying to focus, and your phone keeps buzzing with login requests. Most of us are used to approving these quickly as part of everyday access. 

Attackers know that. 
They’re betting on: 

• You being tired or distracted 

• You assuming it’s just a glitch 

• You approving something “just to stop the noise” 

And once they’re in, they can change passwords, steal data, or worse.

Signs You’re Being Targeted 

• You receive multiple login requests when you haven’t tried to log in 

• Push notifications appear at unusual times (like during the night) 

• You feel tempted to approve a request “just to get rid of it” 

If this happens: 
Change your password immediately. Then alert your IT team. 

How to Protect Yourself 

1. Never approve unexpected MFA requests 
If you didn’t log in, don’t hit “Allow”—even if it looks familiar. 

2. Use number-matching MFA apps 
Some systems now require you to enter a number shown on your screen into the app—making accidental approvals much harder. 

3. Disable push MFA where possible 
Switch to more secure methods like biometric, time-based codes (TOTP), or physical security keys. 

4. Alert IT immediately 
If you think you were targeted (or clicked approve by mistake), speak up. Fast action can stop further damage. 

Final Thoughts: MFA Is Still Essential—But Awareness Is Key 

We strongly recommend MFA for all business accounts—but it’s not magic. Like every tool, it needs smart usage and user awareness to be truly effective. 

In February, we shift gears to look inside: the human factor in insider threats.
