Log into your Microsoft 365 account with any browser using the following link:
If you see the new Microsoft Portal:
You account location is now at the bottom left hand corner:
If you still see the old Microsoft Portal, click on your initials in the top right hand corner.
Select View Account from the form.
Click on UPDATE INFO link on the Security info box.
Click the + Add sign-in method link.
In the dropt down, select Authenticator App and then the Add button.
Click the I want to use a different authenticator app link.
Click the Next button to continue.
On your mobile device, make sure you have the LastPass Authenticator app installed and ready. In the LastPass Authenticator app (NOT LASTPASS VAULT), click on the + symbol to add a new account - it should enable your camera.
Hold you mobile device up to the screen so that the camera can capture the QR code - it will automatically add your Microsoft 365 account into your LastPass account. Don't worry if it also asks you to save it in your LastPass account - you can cancel that if asked.
Click the Next button to continue.
You should have a 6 digit code in the LastPass app on your mobile device - enter it into the space provided and then click the Next button to authenticate.
You should now see Authenticator app as an authentication method.
At the top of that form, click the Change link beside the Default sign-in method and change th option to Authenticator app or hardware token - code
Click the Confirm button to make the change.
I would now log out of the Microsoft 365 Portal and then log back in again to test your LastPast MFA authentication. If it is working, you can now try Outlook – the first time you start Outlook, it will ask you for the LastPass MFA code. Note, the code changes every 30 seconds – don’t worry if you don’t have enough time to enter in the current code, just wait until it changes and then enter in the new code.
