> Is it possible to have passwords hidden?

>From where?  If you enter a password interactively (e.g. in a shell, or
for Tramp, ...) then Emcs should already try to do that for you.

> Something like this:
> * I mark up a password using square brackets: [secret]
> * The marked up password is hidden: ********
> * When I copy a region containing the hidden password, the password
>   ends up in plain-text in the kill ring!

So you mean the password is in a file and you want to write a new mode
specific to that kind of file where the password is not displayed (but
kill&yank still copy the real text)?
That's easy to do, yes.
