GrayPass

About

Login tells you who signed in. GrayPass helps apps check who’s behind sensitive actions and whether they’re authorized before those actions go through. It combines identity, device and session context with behavioral signals like typing rhythm, cursor movement and scrolling. Before a sensitive action goes through, GrayPass evaluates that evidence against your team’s policy and returns a decision: allow, challenge, hold or deny. Your app enforces the decision. This applies to actions like exporting sensitive data, changing admin permissions or allowing an AI agent to act on someone’s behalf. Allowed actions receive short-lived, signed proof tied to the exact action and your app. Your existing login and authentication stack stays in place.
