Sometimes abbreviated as PWD (not to be confused with the Linux pwd command), a password is a set of secret characters or words utilized to gain access to a computer, web page, network resource, or data. Passwords help ensure that computers or data can only be accessed by those who have been granted the right to view or access them.
