Who can advise the server for authentication?

Question

C++ / C#

I want to add authentication for users to my application.
I see the following system:
When the application starts, the user is shown a form where he enters his login and password, then the password is sent to the server, and if such a login / password is in the database, a positive response comes from the server.
It is also necessary that the user has the opportunity to create a user, but in such a way that it would have to be confirmed by the server administrator.
I would like to communicate with the server via https using your certificate.
Tell me, please, are there such solutions or do you need to fence your bike?

Answer 1

I recently released a library with OAuth social media authentication forms . At the moment there are clients for 17 popular services.
The source code is open , distributed under the Apache 2.0 license .
Usage example:

// создаем форму для Dropbox
var login = new DropboxLogin("5nkunr8uscwfoba", "n7x9icfwoe6dehq") { Owner = this };
// показываем форму
login.ShowDialog();
// если пользователь авторизован
if (login.IsSuccessfully)
{
  // можем получить маркер доступа и использовать для работы с API Dropbox
  MessageBox.Show("Маркер доступа: " + login.AccessToken.Value);
}

Joomla 3.x has an API and can work over https.
Install on a web server, on a client - write code to work through the API.
Ready.
