Dear Dave Korn, DK> How about one-time passwords? Just go ahead and *let* them keylog it all DK> they like; by the time they've snarfed a pw, it's no use any more. (See DK> S/Key for more details.) ITAN I hear you scream. Oh yes.. keylogger fakes that the OTP is not accepted, user enters a new one. Thief has a working OTP.
