About GrayPass

Login tells you who signed in. GrayPass verifies the expected person is still in control before consequential actions happen. We use cognitive biometrics like typing rhythm, cursor movement, scrolling, and response timing alongside session and device context to continuously establish assurance. Before actions like approving a payment, changing admin permissions, exporting sensitive data, or letting an AI agent act on someone’s behalf, GrayPass returns allow, challenge, hold, or deny and produces signed proof tied to that action.
