Nowadays its really important that you set up MFA on your systems in the cloud, including 365 email, outlook etc. It means that it is harder to get hacked, and also if there is an attempt then the attacker will be prompted for a code from your MFA app. That code changes every few seconds, unlike your password and so hackers cant collect your credentials and log in without you knowing. For organisations that process personal data and have safeguarding needs this is even more important.
Follow these 6 simple steps to get it set up.
What you will need
- Your Microsoft 365 email address and password.
- Your mobile phone (iPhone or Android).
- Access to a computer or laptop.

Step 3 – Connect your mobile phone
On your mobile phone:

- Select Work or school account.
- Choose Scan a QR code.
- Use your phone’s camera to scan the QR code displayed on your computer.

Step 4 – Confirm that MFA is working (back on your computer)
- Your computer will ask you to test Microsoft Authenticator.
- A notification will appear on your mobile phone.

- Approve the sign-in using your phone’s PIN, fingerprint or face recognition.
- Once the computer confirms successful registration, click Done.
Step 5 – You’re ready
