// what is kdtdev apps?

A platform built by
KDTDev, for KDTDev services.

KDTDev (kdtdev.com) is the development studio behind the platform. KDTDev Apps is the product of that work — a multi-service SaaS ecosystem where every tool shares a single, secure identity layer.

Rather than building isolated applications, every KDT service is architected to plug into a centralized authentication and authorization core. Your organization subscribes to the services it needs, and one login unlocks all of them.

🏗️
Built from the ground up
Every component — auth, services, subscription logic — is custom-built and actively developed by KDTDev.
🔐
Auth is the foundation
The identity system isn't an afterthought — it's the core of the platform. Every service is designed around it from day one.
📦
Modular by design
New applications can be added to the platform without rebuilding auth. The architecture is built to scale with new services over time.
// applications

Purpose-built tools,
shared foundation.

Each application is an independent service connected through a single identity layer — log in once, access everything your organization is subscribed to.

🔄
OAuth / OIDC

Industry-standard authorization with PKCE, JWT tokens, refresh tokens, and key rotation.

// access flow
01

Navigate to any KDT app

Accessing a protected service redirects you to the central auth portal at auth.kdtdev-apps.com

02

Authenticate once

Sign in with your credentials. Optional 2FA adds an extra layer of protection to your account.

03

Token issued

A signed JWT token is issued containing your identity, organization, and permitted service scopes.

04

Redirected to your service

The target application validates your token and grants access based on your subscription tier.

05

Silent SSO for subsequent apps

Already authenticated? Other KDT services recognize your active session automatically.
