OAuth2 - Testing OpenID Connect / OAuth 2.0

Utilities to help you develop using OpenID Connect and OAuth 2.0 are always useful so I've listed out the ones I know about.

Postman - Really useful to for API testing. Requires Chrome.

v2.0 Protocols - OAuth 2.0 Authorization Code Flow - Article that has links to Postman collection to try this out step by step. Azure AD centric.

Inspecting the JWT token - from Auth0.

Outlook OAuth Sandbox - for testing Outlook.Office.com API.

OpenID Connect Playground - from Auth0 - for developers to test and work with OpenID Connect calls.

Demo. instance of IdentityServer - has full stack OIDC / OAuth2 support.

Tying the two together - hooking the playground up with IdentityServer.

Enjoy!
