Rhea Key
Access built on cryptographic proof, not passwords.
Rhea Key is Rhea's cryptographic access and authentication layer. It replaces traditional password-based login with a stronger model built on user-controlled cryptographic authorization.
01 — What it does
A non-custodial access layer.
Instead of depending on usernames, email addresses, phone numbers, and passwords, users authenticate through secure cryptographic proof. This reduces exposure to credential theft, password reuse, phishing, and weak recovery systems.
A user's identity can be verified once and linked to their access layer, enabling trusted authentication across applications, services, organizations, and the wider Rhea ecosystem.
Rhea Key is non-custodial by design. The user retains control of access, while Rhea does not store, reset, or recover the key on the user's behalf.
02 — How it works
A trusted device becomes the key.
Device-based access
Rhea Key turns a user's device into a protected access key for login, connection approval, and device-based authentication.
Biometric unlock
Biometric checks are handled by the device operating system. Rhea Key does not receive, store, or transmit fingerprints, face scans, or biometric templates.
Cryptographic signing
Private authentication material stays protected by the device. Approvals are signed on-device and verified downstream.
Connection approval
Users approve or reject trusted connection requests instead of relying on shared secrets that can leak.
