Common OAuth2 Grant Types
Explore various grant types like Authorization Code, Client Credentials, and their appropriate use cases.
What are OAuth2 Grant Types?
Welcome! In OAuth2, a Grant Type (or 'Authorization Grant') is a method an application uses to get an access token from an authorization server.
Think of it as the specific procedure or negotiation protocol for obtaining permission to access protected resources.
Why Different Grant Types?
You might wonder why there isn't just one way to get a token. Different applications have different security needs and capabilities:
- Web applications with a backend
- Single-page applications (SPAs) in a browser
- Mobile applications
- Command-line tools
- Server-to-server communication
Each scenario requires a tailored, secure approach.
