Two factor authentication services for personal accounts?

Hi Comodo Forums, I am a student at the University of Texas working on a project studying the market for two factor authentication services.

It seems like two factor authentication could solve many current security problems, however people don’t use it because it is cumbersome. I made a survey to find out more about who uses two factor authentication services and why or why not.

If you can help me out with the survey, I would be very appreciative.

Thanks again!
