IDP authentication support with only client id

[chanaka3d]

Description:
Due to the limitations of the current non-production Identity Provider (IDP), it is not currently possible to authenticate using only a consumer key. This limitation poses challenges for implementing frontend web applications without relying on a backend service for authentication.

To address this issue and enable frontend-only web application development, it would be beneficial to enhance the IDP to support alternative authentication methods, such as token-based authentication or OAuth flows that are compatible with frontend frameworks. By implementing such enhancements, developers would have the flexibility to build standalone frontend applications that can authenticate with the IDP without relying on a backend service.
