Remove my email address from the Windows 10 Logon screen

On my laptop, the logon screen of Window 10 displays my email address. This is a bit unfortunate as I also use my laptop in public places and strangers could potentially get my private email address.

On my Desktop computer, my email address isn’t shown so I know that it can be removed.

How do I prevent Windows 10 from showing my email address on the logon screen?
