In certain embodiments, a system receives a first request from a user to perform a function with an enterprise. The system communicates a second request for the user to provide a thought to facilitate authenticating the user with the enterprise. The system receives a string of characters corresponding to the thought. The string may be generated based at least in part upon electromagnetic signals, which the user generates by developing the thought. The system compares the received string to a stored string that corresponds to a thought of the user to authenticate the user. Based at least in part upon the comparison, the system determines whether the user is authenticated to perform the function.
