Researchers show the potential of thought-based authentication using a stock gaming headset that captured EEG signals

On a practical level, the study has its weaknesses. Having to focus on a thought for five to 10 seconds would seem like an eternity in computing, which people expect to deliver instantaneous responses. In addition, the study did not investigate whether an impersonator could successfully use someone's "pass-thought."

Nevertheless, the experiment moves brainwave authentication forward, and shows that the technology is deserving of further study.
