Assuming the getpass is the one the from the std lib, I don't see why you're overriding getPassword at all.

according to the API docs, you should be able to get a custom prompt just by adding a prompt parameter:
http://twistedmatrix.com/documents/8.1.0/api/twisted.conch.ssh.userauth.SSHUserAuthClient.html#getPassword

and you probably don't want to call succeed() on the deferred you are returning, since that likely screws up the whole auth calback chain

if you were looking at this example: http://www.devshed.com/c/a/Python/SSH-with-Twisted/4/
realize that it might be misleading, as the author overrides the __init__ of his SSHUserAuthClient and passes the password in directly
(he does not prompt the user for it)

...or I could be misunderstanding the way the module works... :)

Good Luck!

For the password problem, I think what you want to do is raise an
exception, which will in turn cause your defereds to call their error
backs.  In the error back you can handle the particular error however
you need to.  That's probably something you need to either setup in
the getpass module, alternatively, that may be setup already and just
waiting for you to addErrback() on it.
