What is MFA and why is it important?

A article to help you understand MFA and why we have implemented it. 

What is MFA?

Multifactor authentication (MFA) adds an extra layer of protection to your accounts and sensitive data. When signing in, users are prompted to verify their identity through a second method, making unauthorised access significantly harder.

Why is MFA important?

Setting up MFA greatly strengthens your organisation's security, ensuring that stolen or compromised credentials alone aren't enough to breach your systems. For most organisations, MFA isn't just a best practice; it's a critical security requirement.

MFA blocks around 80-90% of attacks on online accounts. In a recent study, 99.9% of compromised Microsoft accounts lacked MFA.

How does MFA work?

MFA works by requiring additional verification information (factors). Users can’t log in with only usernames and passwords; they must provide additional proof of identity.

3. Enter the code seen in your chosen authenticator app 

4. You are now set up and can enter your account


Logging in with MFA

Once MFA is set up, you will need to use your one-time code (OTP) every time you log in. You can access this via your authentication app.
