Hi,
Currently, all authentication failures return the same error code (InvalidGrant), making it difficult to distinguish between different failure reasons on the front end.
Introducing specific error codes (account_locked, account_inactive, and invalid_grant) will allow us to check whether an account is locked out, inactive, or if the credentials are invalid, enabling the front end to handle these scenarios more effectively.
