Claims a workable way to authenticate an app installation without user interaction by having each device generate an RSA keypair, register the public key plus two 64-bit nonces, and sign a one-time nonce per request so the OpenID Connect provider can validate and issue a JWT. Uses IdentityServer for the provider, TLS + certificate pinning, handles replay and network failures with a 400/resync flow and revocation if out of sync, requires at least one auth/day. Raspberry Pi demo shows it working, code on GitHub. IdentityServer + custom OpenID flow RSA keypair + OTP-like nonces
