Pseudentity

Identity Provider for Development

Identity Provider & Visual Companion

Pseudentity is a stateless OpenID Connect (OIDC) provider and visual companion for the pseudata ecosystem. Add “Login with Pseudentity” to your apps for testing and development—no real auth provider setup required.

Built on PseudoID (UUID v8), every identity is entirely stateless—no database, no sessions. Just decode the ID to regenerate the complete profile on demand.

Key Features

OpenID Connect Provider

Add “Login with Pseudentity” to your apps. OIDC-compliant with signed JWTs—no sessions, no database. Perfect for testing auth flows without configuring real identity providers.

Profile Viewer

Visualize any generated user with a rich UI, avatar, and metadata. Jump to any user instantly using their PseudoID.

Mock Enterprise (SCIM 2.0)

Test user provisioning flows with infinite, paginated employee lists. Perfect for testing Okta or Azure AD integrations.

Zero Database

Entirely stateless—uses CPU (math) instead of storage. Every profile is calculated on-demand from the PseudoID.

Why Pseudentity?

Testing authentication in development typically requires:

Expensive third-party providers - Auth0, Okta, or other SaaS identity platforms
Managing test databases - Storing and maintaining fake user accounts
Coordinating credentials - Sharing test logins across teams
Resetting state - Cleaning up between test runs

Pseudentity eliminates all of this by making identities completely stateless and deterministic. No database. No sessions. Just pure math.

How It Works

Pseudentity uses PseudoID, a custom UUID v8 format that encodes generation parameters directly into the 128-bit ID space:

SSSSSSSS-SSSS-8SSS-vSTT-TTIIIIIIIII

64 bits: World Seed (universe ID)
16 bits: Type Sequence (User = 101)
40 bits: Index (0 to 1.1 trillion)

This allows any server to “inflate” a full user profile instantly just by decoding the ID—no database lookups required.
