Avast Password extension on IE11 not Chrome

I am new to Avast… I am trying to change extensions from Chrome to IE11. How is this done and is it even possible?

Extensions for Chrome and IE are not compatible.

IE11, which this user is trying to use, is not supported by passwords, even though the FAQ referenced states Internet Explorer is supported.
