Hydra-Bridge: Add OAuth2/OIDC to an Existing System Without Migration
Modern applications expect OAuth2 and OpenID Connect (OIDC), but many systems already have a working login, SSO cookies, and user database. Migrating users, passwords, and sessions to a new Identity Provider is risky and expensive.
Hydra-Bridge demonstrates a simple idea:
👉 add OAuth2/OIDC on top of an existing authentication system — without changing or migrating it.
The Core Idea
Keep your current authentication system as the source of truth.
Use Ory Hydra only as the OAuth2/OIDC engine, and add a small Bridge service that connects Hydra with your existing login flow.
