Don't tell anyone your password
October 15, 2007
One way someone could learn your password is to phone you claiming to be from another part of your organization, maybe your IT or Audit teams, and say they need your account details to let them investigate problem. This should never be necessary. Good systems are set up so that nobody but you will ever know your password and authorized IT workers have their own accounts giving them access to what they need.
