7 Mistakes You’re Making with MFA and Cloud Security (and How to Fix Them)

MFA and Cloud Security

As we move further into 2026, the way we work in Yorkshire has changed forever. From the bustling financial hubs in Leeds to the independent businesses in Skipton and Ripon, the “cloud” is no longer a buzzword: it is the office. Multi-Factor Authentication (MFA) is often touted as the “silver bullet” for cloud security, but simply “having it” isn’t enough if it is configured incorrectly.

At Fresh Mango Technologies, we see many local businesses making the same fundamental errors. Here are the seven most common mistakes businesses make with MFA and cloud security, and how you can fix them today.

1. Relying on Weak MFA Methods (Like SMS)

Many businesses believe any MFA is sufficient. However, receiving a code via SMS is now considered a “weak” method due to “SIM swapping” attacks.

 

The Fix: Move toward “App-based” authentication like Microsoft Authenticator or hardware tokens (like YubiKeys). For more info, check out the NCSC resources on MFA.

2. Assuming the Cloud Provider Handles All Security

One of the biggest misconceptions in managed IT services in Yorkshire is that the cloud provider is responsible for everything.

 

The Fix: You are responsible for the data and identities inside the cloud. Don’t assume default settings are enough; they are often designed for ease of use, not maximum security.

3. The "VIP Exception": Not Enforcing MFA for Everyone

Secure hardware MFA key and smartphone on a desk.

Senior management often exempts themselves from MFA because it’s “inconvenient.” This is dangerous as they are “High Value Targets.”

 

The Fix: MFA must be mandatory for every user. If friction is a concern, our team can streamline the process so it’s secure without being a burden.

4. Forgetting About "Shadow IT"

  • Shadow IT refers to employees using apps like Trello or Dropbox without IT’s knowledge. These accounts rarely have MFA, creating a back door into your business.

     

  • The Fix: Conduct a “cloud audit” and bring these tools under the umbrella of your managed IT services Leeds.

5. Ignoring Session Timeouts and "Remember Me" Risks

Staying logged in for 30 days is convenient but risky. If a device is stolen, an attacker can hijack that session without needing a password.

 

The Fix: Configure sensible session timeouts, especially for sensitive finance or HR portals.

6. Lack of Training on "MFA Fatigue" Attacks

Attackers send dozens of push notifications hoping a tired user will click “Approve” just to make them stop.

 

The Fix: User training is key. Your team needs to know to Deny any request they didn’t trigger. Learn more about our cyber security Yorkshire approach.

7. Not Having a Local Partner to Manage Security Proactively

Cloud security isn’t “set and forget.” Relying on a reactive provider who only fixes things when they break is a recipe for disaster.
