发明名称 Method and system for providing password protection
摘要 Access is granted to a portion of a computing system, such as to a configuration menu of a telephone system. In order to grant access, a password is received from a user. A variable password is also calculated. The variable password varies with time. For example, the variable password varies with a current date and with a time of day stored by the computing system. The password received from the user is compared with the calculated variable password. When the password received from the user is equal to the calculated variable password, access is granted.
