Okta OIDC/OAuth response error_description


I am trying to test an application access and when the user is not assigned to an app, we receive the below URL with query parameters. Is the error_description can be removed or the text can be updated?



No, this message cannot be changed. As per OIDC spec, this error is returned back to your application via the registered redirect_uri, which means you can configure your application to catch these types of errors and present a more user-friendly error message/screen.
