Swagger/Swashbuckle: OAuth2 with Resource Owner Password Credentials Grant

Question

I'm trying to use Swashbuckle 5.0.x with OAuth2. I want to use OAuth2's Resource Owner Password Credentials Grant. I basically only want to ask for a token first and include this token in each request (e.g. no need for scopes).

Can anyone help with this? How do I have to configure swagger/swashbuckle?

Thank you @Dunken. Your answer almost solve my problem, but to make it work with latest Swashbuckle version I had to change it a bit like this

$('#explore').off();

$('#explore').click(function () {
   var key = $('#input_apiKey')[0].value;
   var credentials = key.split(':'); //username:password expected

$.ajax({
    url: "yourAuthEndpoint",
    type: "post",
    contenttype: 'x-www-form-urlencoded',
    data: "grant_type=password&username=" + credentials[0] + "&password=" + credentials[1],
    success: function (response) {
        var bearerToken = 'Bearer ' + response.access_token;

        window.swaggerUi.api.clientAuthorizations.add('Authorization', new SwaggerClient.ApiKeyAuthorization('Authorization', bearerToken, 'header'));
        window.swaggerUi.api.clientAuthorizations.remove("api_key");
        alert("Login successfull");
       },
       error: function (xhr, ajaxoptions, thrownerror) {
        alert("Login failed!");
       }
    });
});
