See the other email I sent on this thread in re: to reducing the
secretness of the password.  You can't use _reversible_ crypto to
protect the now-plaintext password.  There might be justification for
doing so to make the logs harder to access, but it is not useful for
giving one an excuse to go logging usernames at the console.

Furthermore, any situation where one needs so much security one is
worrying about password guessing at the console probably should also
require restricted and logged physical access to the console, which is a
simpler solution.  Several guesses show up in the logs and you just go
to the person who was signed in at the colo in your cage.
