Cyber Security Awareness Month 2025
October marks Cyber Security Awareness Month, and this year’s theme is all about the “Core 4” habits that help businesses stay secure online:
- Spotting and reporting scams
- Using strong passwords and password managers
- Enabling multi-factor authentication (MFA)
- Keeping software and systems updated
This week, we’re focusing on MFA, a simple but powerful tool that can stop most cyber-attacks before they even start.
What Is MFA and Why Should HVAC Teams Care?
Multi-factor authentication (MFA) might sound like something only IT departments worry about, but it’s actually very relevant to HVAC businesses. Think about how many systems your team accesses: project management tools, supplier portals, building automation platforms, even email. If any of those accounts are compromised, the fallout could be costly.
MFA works by asking for more than just a password. It adds extra layers of security, like:
- Something you know – a password or PIN
- Something you have – your phone or a security key
- Something you are – fingerprint or facial recognition
Even if someone gets hold of your password, MFA makes it much harder for them to get in. Microsoft says it can block over 99% of account hacks. That’s a big deal when you’re managing sensitive client data or remote access to building systems.
More HVAC Professionals Are Using MFA
The good news? Awareness is growing. A recent study found that 81% of people now understand what MFA is, and 66% are actively using it to protect their accounts. That’s a solid step forward for industries that are increasingly reliant on digital tools.
What MFA Options Work Best for HVAC?
Depending on the platform, you’ll see a few different MFA methods:
- SMS or email codes – easy to use but not the most secure
- Authenticator apps – generate time-sensitive codes
- Push notifications – approve logins with a tap
- Biometrics – fingerprint or facial recognition
- Hardware tokens – physical devices for high-security access
For HVAC contractors who are often on the move or working across multiple sites, authenticator apps and biometrics offer a good mix of security and convenience. Hardware tokens are ideal for protecting access to critical systems like BMS platforms or financial tools.
AI Is Making MFA Smarter
Artificial intelligence is quietly improving MFA behind the scenes. Here’s how:
- Risk-based authentication – AI checks if the login attempt matches your usual behavior (device, location, time). If not, it asks for more proof.
- Behavioral biometrics – it learns how you type or move your mouse, adding invisible layers of protection.
- Real-time threat detection – AI can spot suspicious activity and shut it down before damage is done.
This is especially useful for HVAC teams who log in from different locations or devices. AI helps keep things secure without slowing anyone down.
But Cyber Criminals Are Getting Smarter Too
Unfortunately, attackers methods are also evolving. Some of their latest tricks include:
- Fake login pages that steal both your password and MFA code
- Voice cloning and deepfakes to impersonate trusted contacts
- MFA fatigue attacks, where they bombard you with login prompts until you accidentally approve one
That’s why it’s crucial to use phishing-resistant MFA methods and stay alert to anything that feels off.
MFA Best Practices for HVAC in 2025
To get the most out of MFA, keep these tips in mind:
- Use stronger methods – go for authenticator apps, biometrics, or hardware keys over SMS or email
- Don’t approve random prompts – if you didn’t try to log in, don’t say yes
- Set up backups – register more than one method in case you lose your phone
- Secure your most important accounts first – like email, supplier portals, and building control systems
Final Word
MFA isn’t just a tech buzzword, it’s a practical, effective way to protect your HVAC business. Whether you’re managing remote teams, accessing building systems, or handling sensitive client data, MFA adds a layer of security that’s well worth the few extra seconds it takes to log in.
