They required two-form-factor authentication—in this case, that included using the SecurID described earlier, a product from a company called Security Dynamics. Every employee who needs to connect remotely is issued a secret PIN and is given a device the size of a credit card to carry with him or her that displays a six-digit passcode in its display window. That code changes every sixty seconds , seemingly making it impossible for an intruder to guess it. Anytime a remote user needs to dial in to Motorola’s campus, he or she has to enter a PIN followed by the passcode displayed on their SecurID device.
