@section Entering passwords
Sometimes, you may need to enter a password into Emacs. For instance,
when you tell Emacs to visit a file on another machine via a network
protocol such as FTP, you often need to supply a password to gain
access to the machine (@pxref{Remote Files}).
Entering a password is, in a basic sense, similar to using a
minibuffer. Emacs displays a prompt in the echo area (such as
@samp{Password: }); after you type the required password, press
@key{RET} to submit it. To prevent others from seeing your password,
every character you type is displayed as a dot (@samp{.}) instead of
its usual form.
Most of the features and commands associated with the minibuffer can
@emph{not} be used when entering a password. There is no history or
completion, and you cannot change windows or perform any other action
with Emacs until you have submitted the password.
While you are typing the password, you may press @key{DEL} to delete
backwards, removing the last character entered. @key{C-u} deletes
everything you have typed so far. @kbd{C-g} quits the password prompt
(@pxref{Quitting}). @kbd{C-y} inserts the current kill into the
password (@pxref{Killing}). You may type either @key{RET} or
@key{ESC} to submit the password. Any other self-inserting character
key inserts the associated character into the password, and all other
input is ignored.
