Hi @lakpahana,

Using the Password Grant Type when a refresh token fails is not considered a standard practice in OAuth2. If this behavior is required for a specific reason, it should be implemented in the user code rather than being handled within the library.

Thanks for the feedback. I will implement it in the application itself.
