DEMO
Step 1

Enroll Mode

Click 'Enroll' mode and type in a username. It can be anything you like! We'll remember you. When you're ready, you can start.

1
Step 2

Camera Setup

If you have a camera, activate it - it adds another layer to the authentication. If not, that's also fine! We can work without it too. After you activate it, you'll see some red dots on your screen. Track the dots with your eyes to help calibrate the camera! If you didn't activate it, just skip this step and follow through with the next steps.

Step 3

Stroop Test

You're going to play a 'Stroop test'. You'll see text (colour names) written in different colours. Click the colour bar that matches the colour the word is written in. For example, if it says 'Red' in Yellow text, click Yellow.

Step 4

Typing Test

Straight after the Stroop test, you'll be asked to type 'graypass is my passport'. It's a typing test at your OWN pace, so feel free to type however you like.

Step 5

Login & Verify

You're done the test! Now, type in your username again, click 'Login' mode, and redo the test. If your behaviour matches your previous attempt, you're in! If not... well you can always try again! Have a go!

Frequently Asked Questions

Can you steal my thoughts?

No. We only store encrypted timing vectors & salted hashes. Your actual thoughts, personal information, or biometric data are never captured or stored.

What data do you keep?

Only essential, anonymized data is briefly stored to power authentication. It's encrypted at rest, regularly purged, and never includes personal thoughts or identifiable biometric information.
