0DINID

0DINID is a modern, centralized Identity Provider (IdP) built with .NET 8, supporting robust authentication standards like OAuth 2.0, MFA, and SSO. It’s designed to act as the core authentication layer across multiple applications, offering secure, flexible, and extensible identity management with advanced features like time-based OTPs, email/SMS login, and privileged profile access.

What It Does

  • Centralized Single Sign-On (SSO) across multiple apps

  • Supports OAuth 2.0 flows and external login providers

  • Multi-Factor Authentication using:

  • Email-based OTP

  • SMS-based OTP

  • ⏱ TOTP via authenticator apps

  • Application registration and configuration via admin panel

  • Full user profile management with fine-grained access delegation

  • Built-in health checks and monitoring endpoints

  • Privileged access workflows for sensitive user data

  • REST API-first design for frontend/backend integration
