MFA: why secure sign-in is the most important measure

If you take one security measure, let it be MFA. Multi-factor authentication is the simplest and most effective protection against intrusion into your accounts. In this article you read how it works and why it is indispensable. It is also one of the first steps towards NIS2.

What is MFA?

MFA (multi-factor authentication) means that besides your password you need a second step to sign in, for example a code or an approval on your phone. Even if someone knows your password, they cannot get in without that second step. Your account is thereby much better protected.

Why is MFA so important?

Because passwords alone are no longer enough. Passwords leak, are guessed or intercepted via phishing. MFA catches that: it makes a stolen password practically worthless. It is one of the few measures that makes a big difference with little effort, and therefore step 4 in our NIS2 checklist.

Is MFA mandatory?

There is no separate law that literally requires MFA, but it is indispensable in practice and aligns directly with what NIS2 expects: appropriate measures against unauthorised access. More and more insurers and clients also set MFA as a requirement. So waiting is unwise.

On which accounts do you enable MFA?

On all of them, but start with the most important. Email, Microsoft 365 and accounts with access to sensitive data are the most vulnerable. Ultimately you want MFA on every business account, because one unprotected account is enough for an attacker.
