R70 Net Logon

When using a network share as a source or destination location there's now an option to configure the username/password for it.

Having considered several options on how to massage this into the UI, I ended up using an in-editbox button and these are the icon options for this button.

Here's how it looks in the app - attached.

Using second from the top icon now, but not totally set it. Any thoughts? Is it easy enough to understand what it represents?
