How it fits together
Two independent products. One shared principle.
Keep customer choice and authority at the center. Rhea Data brings control to supported work across connected infrastructure. Rhea Key enables passwordless sign-in on participating sites, independently of Data.
Division of responsibility
Choose Data, Key—or both.
Control your data
Rhea Data
Rhea Data brings permissions, protection and supported data work together across your connected infrastructure.
Product pageSign in without passwords
Rhea Key
Independent passwordless sign-in for participating websites and applications. Approve on your device; the website verifies and creates its own session. Rhea Data is not required.
Product pageSystem flows
Separate responsibilities. Clear connections.
Use Key for independent sign-in, Data for permitted work, or both together. Data uses Key for sign-in and connection approval; adopting Key on another website does not require Data.

Selected relationship
One familiar passwordless sign-in, independently of Data.
A participating website can integrate Rhea Key without integrating Rhea Data. On desktop you scan its QR code, confirm two digits and approve on your device; the website verifies the response.
The website verifies the signed response before creating its own session. The private key is not sent to the website.
Every website must choose to integrate Key. Broad global adoption is the goal, not current universal availability. Supported mobile flows open Key directly.
