Phone signing vault for agents — analogous to Authy or Google Authenticator, but for signature requests instead of one-time passcodes.
HOW IT WORKS
Pair Recto Agentic with any service running a Recto bootloader. The service can then request your approval for cryptographic operations: signing transactions, authorizing API calls, granting time-bounded capabilities. Each request is reviewed on your phone and confirmed with biometric authentication. Private keys never leave the device's Android StrongBox.
KEY FEATURES
• Phone signing vault — keys never leave the device
• Android StrongBox-backed biometric approval (fingerprint, Face Unlock)
• Pair with multiple services, each request audit-detailed
• QR scanning for cross-device verification
• No accounts, no sign-ins, no external login
• Zero data collection — no analytics, no crash reporting, no third-party SDKs
• Open source (Apache 2.0)
WHO IT'S FOR
Developers and operators of services that need cryptographic approval workflows. Recto Phone is the operator-side companion to any service running a Recto bootloader.
