Passwords are a common form of <a href="http://en.wikipedia.org/wiki/Authentication" target="_blank">authentication</a>. Full security requires that the password be kept <a href="http://en.wikipedia.org/wiki/Secrecy" target="_blank">secret</a> from those not allowed access. The use of passwords goes back to ancient times. Sentries guarding a location would challenge for a password or watchword. They would only allow a person in if they knew the password. In modern times, passwords are used to <a href="http://en.wikipedia.org/wiki/Access_control" target="_blank">control access</a> to protected computer <a href="http://en.wikipedia.org/wiki/Operating_system" target="_blank">operating systems</a>, <a href="http://en.wikipedia.org/wiki/Mobile_phone" target="_blank">mobile phones</a>, <a href="http://en.wikipedia.org/wiki/Cable_TV" target="_blank">cable TV</a> decoders, <a href="http://en.wikipedia.org/wiki/Automated_Teller_Machine" target="_blank">automated teller machines</a> (ATMs), etc. A typical <a href="http://en.wikipedia.org/wiki/Computer_user" target="_blank">computer user</a> may require passwords for many purposes: logging in to computer accounts, retrieving <a href="http://en.wikipedia.org/wiki/E-mail" target="_blank">e-mail</a> 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 are harder to guess, a desirable property. Some passwords are formed from multiple words and are more accurately called a <a href="http://en.wikipedia.org/wiki/Passphrase" target="_blank">passphrase</a>. The term passcode is sometimes used when the secret information is purely numeric, such as the <a href="http://en.wikipedia.org/wiki/Personal_identification_number" target="_blank">personal identification number</a> (PIN) commonly used for ATM access. Passwords are generally short enough to be <a href="http://en.wikipedia.org/wiki/Memory" target="_blank">memorized</a>.<img src="http://bmajnun.files.wordpress.com/2008/05/password_star2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://www.subhub.com/custom/padlock.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
