Explain the necessary password etiquette to be followed by the users of an information system.

 Once users create a strong password, they need to protect it with proper behavior. Proper password etiquette is one of the marks of a business professional. Users should never write down their password, and should not share it with others. They should never ask others for their passwords. If, in a work-related or emergency situation, someone asks for the password, users are advised not to give it out. Instead, it is better for the user to get up, go over to that person's machine, and enter the password. Users should be present while their password is in use, and should ensure that their account is logged out at the end of the activity.
