Define the request
Create a fresh challenge connected to a user, agent, service, or specific operation.
Fresh proof for every sensitive boundary.
Pteri-Auth gives applications a signed-challenge verification flow for users, AI agents, and services. Use it at login or when a protected action requires new, scoped authority.
How it works
Challenge. Review. Sign. Verify.
Your application remains responsible for its own identity model, access policy, and final action. Pteri-Auth supplies a cryptographic verification result that the application can evaluate.
Review the intent
The authorized signer reviews the request and produces a cryptographic signature.
Apply your policy
Validate identity and request context, then allow or reject the action in your application.
Launch use cases
One control for several kinds of actor.
Start with the workflow where stale sessions, shared credentials, or broad authority create the greatest risk.
Human authentication
Signed-challenge login and step-up verification before administrative or financial actions.
Agent and service authorization
Distinct identities and scoped authority for automated actors before sensitive tool or API calls.
High-risk recovery and transfer
Add fresh approval to workflows such as account recovery or eSIM transfer where control of a phone number is insufficient.
Integration responsibilities
Clear boundaries from the start.
Confirm the signing mode, key-custody model, production endpoints, limits, and support commitments for your selected workflow before production deployment.
Application
Creates the challenge, enforces uniqueness and expiry, stores required context, and makes the final authorization decision.
Pteri-Auth
Supports challenge verification and returns the result required by the integration contract.
Signing interface
Uses the supported wallet or approved signing method for the selected customer architecture.
Prove one workflow before expanding.
