Passfaces uses your brains' natural ability to recognize familiar faces. Go through the enrollment process and follow the directions. It's really easy. Remembering and recognizing faces is entirely intuitive.
You've heard the saying "I never forget a face". That's true. This ability has evolved over thousands of years. Think of people you haven't seen for a long time. Although you may not remember their name, you recognize them. Passfaces works on the same principle.
You will increase your probability of recognizing your Passfaces by returning to your log on within a couple of days of going through the enrollment process.
Very few people have a condition known a prosopagnosia which means that they are unable to recognize faces. If you have prosopagnosia or experience real difficulty completing the Passfaces enrollment process, please contact your systems administrator.
