It is unclear what exactly is the issue, but have in mind that database connections which are the type of connection that would align to application-specific credentials (username and password) identify the user only with two pieces of information; a username/email and a password so there is no notion of a third piece of information like the client ID represented in the picture.
With regards to language; if you use Lock in the hosted login page you can configure its language before showing it, but Lock itself does not have any UI to let the end-user switch between languages so any support for that would need to be a custom implementation.
