# Register OAuth Client App

**ID:** DEV-005
**Priority:** Medium
**Status:** Planned

## User Story
As a developer, I want to register my application as an OAuth client so that users can authorize my app to access their data using standard OAuth 2.0 flows.

## Acceptance Criteria
- [ ] Register OAuth 2.0 client application
- [ ] Support Authorization Code flow
- [ ] Support PKCE for public clients (mobile/SPA)
- [ ] Configure allowed scopes per client
- [ ] Consent screen customization
- [ ] Token endpoint for code exchange
- [ ] Refresh token support
- [ ] Client credentials flow for server-to-server

## Technical Notes
- OAuth keywords in package.json suggest this is planned
- Implement OAuth 2.0 authorization server endpoints
- Scopes: openid, profile, email, organizations
- Consider OpenID Connect for identity layer
- PKCE is required for mobile and SPA security
