How do I set the admin favicon?

Question

How do I change the favicon that displays while in the Magento 2 admin? It currently displays the favicon for the base website, but I would like it to display a custom favicon (and not the Magento logo).

To be clear, I want a different favicon in the frontend from the backend admin.

I'd prefer a way via the admin, but can edit code if necessary.

If you want to changes then you need to create an admin Theme.

First at app/design/adminhtml directory create a new <Vendor>/<admin_theme> directory.
