How Multi-Factor Authentication (MFA) Strengthens Server Security and Prevents Hacks

[johny899]

Have you ever worried that someone will find out your password? Of course you have, we all have. That’s what makes Multi-Factor Authentication (MFA) so important. Think of MFA as a second lock on your door; even if someone gets your key, they still can't get through the second lock. Let’s look at how MFA helps protect your servers from attackers.

Why Passwords Aren’t Enough​

We can all admit that most of us use the same password in more than one place. It feels easier, but it is risky. That same password can be used to access your server if another site is hacked.

That's why MFA is important - it asks you for something else in addition to entering your password, such as a number sent to your phone, a thumbprint, or tapping an app on your phone. Even if someone is able to get your password, they can’t gain access without the second factor. Smart thinking!

How MFA Protects Servers​

Your server is like the brain of your online work. It houses your files, your data, your applications, and if someone breaks into it, they have the potential to do considerable damage. MFA protects your servers by adding another layer of protection.

Here is what it does:

• Cuts off hacker access even if they have your password.
• Thwarts brute force attacks, since the codes change every few seconds.
• Protects you if you log in remotely even if it isn't on your office network.
• Adds one last step before granting anyone privilege to post any changes on the server.

Has a teammate ever shared their password ---by accident, right? MFA stops those little mistakes from becoming a big headache.

Is it worth using MFA?​

Yes. I set up MFA on my own server a few years ago, and yes, it adds a tiny extra step. But, I can sleep at night! It is like locking your door and setting an alarm. You don’t leave home without it, do you?
