password (redirected from Passcode)

password

A secret word or code used to serve as a security measure against unauthorized access to data. It is normally managed by the operating system or DBMS. However, the computer can only verify the legitimacy of the password, not the legitimacy of the user. See NCSC.

Password Tips from the NCSC

CHANGE PASSWORD FREQUENTLY - The longer you use a password, the higher the risk.

USE GOOD PASSWORDS - Don't use persons, places or things that can be identified with you.

DON'T DISCLOSE YOUR PASSWORD - Your password is as valuable as the information it protects.

INSPECT YOUR DATA - If you suspect someone has tampered with your files, report it immediately.

NEVER LEAVE AN ACTIVE TERMINAL UNATTENDED - Always log out or lock your terminal before leaving it.

REPORT SUSPECTED COMPUTER ABUSE - Whether directed against you or not, abuse or misuse of your computer resources only hinders the timely completion of your tasks.

(security)

password - An arbitrary string of characters chosen by a user or system administrator and used to authenticate the user when he attempts to log on, in order to prevent unauthorised access to his account. A favourite activity among unimaginative computer nerds and crackers is writing programs which attempt to discover passwords by using lists of commonly chosen passwords such as people's names (spelled forward or backward). It is recommended that to defeat such methods passwords use a mixture of upper and lower case letters or digits and avoid proper names and real words. If you have trouble remembering random strings of characters, make up an acronym like "ihGr8trmP" ("I have great trouble remembering my password").
