Privacy-first identity platform

Add Sign in with Datheos to your app

Let users share their verified personal data with your app on demand. No storing PII — data lives in Datheos, always fresh, always consented.

Register your app

Consent-first

Users declare which data is essential vs optional. They see exactly what your app needs and why.

Always fresh

Call /oauth/userinfo whenever you need data. It's live from Datheos — nothing to sync.

10-line integration

Install @datheos/sdk, add credentials, wire up 3 routes. Done.
