The hardware key (dongle) gives users assurance that the program can be easily installed and used, for example, on a new computer.
#SENTINEL HL DEVICE ACTIVATION CODE#
Under certain circumstances, the activation code may not be immediately available and users have to wait till they get it (e.g., activation by e-mail). Activation of the program brings some disadvantages, such as that the program can be activated only on the allowed number of computers and the activation is always time-limited (up to 1 year) and needs to be repeatedly renewed.

Hardware keys are very effective copy protection devices, because they cannot be duplicated by the user. Upon startup, the application looks for the key and will run only if the key contains the appropriate code. A Hardware Key (HASP), also called a "dongle", is a software copy protection device that plugs into the USB port of the computer.
