About GrayPass
Summary
GrayPass verifies that the authenticated user is still in control of a session at the moment a consequential action executes, closing the gap between login and action. It analyzes cognitive biometrics, including keystroke timing, pointer movement, and scroll patterns, alongside session and device context to assess continuous control. Before an action such as a payment approval, permission change, sensitive data export, or AI agent execution proceeds, GrayPass returns an allow, challenge, hold, or deny decision and generates signed proof tied to that specific action.

From the Y Combinator listing
Verify that the expected person is in control before key actions.
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.
