# Basic No license fee
The Basic license is available free of charge for its core functionality.
# Benefits
- HWG-compliant profession check
- Self-service management; integration via login button in your own system
- Extensive test setup; login in 6 languages
- Basic OAuth2 authentication (Authorization Code Flow)
# Description
Implement HWG-compliant protected areas without your own user management or support. DocCheck provides registration, profession verification, login, and user support; you define which professional groups may access your content (see Login process).
The Basic license is automatically available for every login client you create in your company account in DocCheck Access (opens new window). Optionally, you can implement the OAuth 2.0 Authorization Code Flow to integrate authentication into your systems.
# Features
- Manage in DocCheck Access (create and configure login clients)
- Login button for easy embedding
- Company passwords and test user
- Basic OAuth2 authentication: Authorization Code → Access Token (auth proof only), see OAuth2 service
- Quickstart: step-by-step setup in the Quickstart guide
# More options with Economy and Business
If you need more than authentication, Economy and Business add features for data-driven and more flexible login flows, for example:
- Parameter passthrough via
state: pass parameters through the login. Parameter passthrough is only supported via thestateparameter and is available starting with Economy. - Dynamic routing via
state: choose the target after users return from login by mapping the returnedstatevalue in your application. - User data retrieval: retrieve granted user data after consent through the OAuth2 user data endpoint.
Additional Economy and Business features are listed in the feature table in the License overview.
