OpenID config validator

OpenID Configuration Endpoint Validator

.well-known urls

An authorization server will often have a .well-known endpoint used for discovery of its features.

For example, the OpenID Connect configuration can be found at /.well-known/openid-configuration.
Example: https://example.com/.well-known/openid-configuration
Example: https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration

Use JSON input instead of endpoint URL

This tool validates the claims of an OpenID Connect provider's configuration endpoint. It fetches the OpenID Connect configuration from the specified URL and validates the claims against the OpenID Connect specification. The tool also checks for common misconfigurations and provides suggestions for improvement.
