This article will show you how to set up and use MFA.

Set up MFA

Before you start

To set up MFA quickly and easily you’ll need:

  • a mobile phone that has internet access and can run apps (this can be a work or personal phone)

  • a second device with a web browser, preferably a computer, to display the web pages on which you will set up MFA

  • to ensure the date and time are set correctly on each device

It is possible to set up MFA using only one device but we don’t recommend it.

Instructions

  1. 💻 On your computer, open a web browser and go to https://mysignins.microsoft.com/security-info and sign in with your Essex email address and password.

  2. Once signed in, choose Add sign-in method

Add a backup authentication method

We strongly recommend you add more than one authentication method so you aren't reliant on a single device.

  1. Go to https://mysignins.microsoft.com/security-info and sign in with your Essex email address and password.

  2. Choose Add sign-in method

  3. Choose your preferred backup authentication method.

Remove an authentication method

  1. Go to https://mysignins.microsoft.com/security-info and sign in with your Essex email address and password.

  2. Select the Delete option, next to the method you want to remove.

If you delete your default sign-in method, the next available method will automatically become your default method.

Help and troubleshooting

I don’t have my phone with me

If you don’t have your primary authentication method with you and you do not have an alternative method, please contact the IT Helpdesk.

I have received a sign-in request that wasn't me

If you receive a sign-in request that wasn't you, please contact the IT Helpdesk immediately.

I have a new phone and I want to add it

You'll need to set up MFA each time you get a new device. The quickest way to do this is to:

  1. Go to https://mysignins.microsoft.com/security-info and sign in with your Essex email address and password.

  2. Choose Add method and then follow the instructions onscreen to add a new device.

  3. Once you've added your new device, Delete the old device from your list of methods.
