A Â password is a secret Â word or string of Â characters that is used for Â authentication, to prove identity or gain access to a resource (example: an Â access code is a type of password). The password should be kept Â secret from those not allowed access.
The use of passwords is known to be ancient. Sentries would challenge those wishing to enter an area or approaching it to supply a password or Â watchword. Sentries would only allow a person or group to pass if they knew the password. In modern times, Â user names and passwords are commonly used by people during a Â log in process that Â controls access to protected computer Â operating systems, Â mobile phones, Â cable TV decoders, Â automated teller machines (ATMs), etc. A typical Â computer user may require passwords for many purposes: logging in to computer accounts, retrieving Â e-mail from servers, accessing programs, databases, networks, web sites, and even reading the morning newspaper online.
Despite the name, there is no need for passwords to be actual words; indeed passwords which are not actual words may be harder to guess, a desirable property. Some passwords are formed from multiple words and may more accurately be called a Â passphrase. The term Â passcode is sometimes used when the secret information is purely numeric, such as thepersonal identification number (PIN) commonly used for ATM access. Passwords are generally short enough to be easily Â memorized and typed.
