title: Spring Web Application Authentication (advise)
body: <p>I'm going to start the development of an web application system with multiple modules. The system will be built over Springframework, which is the reason why I'm going to use Spring Security. However, I have doubts about the choice of the authentication system.</p>
  
  <p>The idea is to create restufull services that will be consumed by extjs pages (in case of web application) and mobile application.</p>
  
  <p>Please suggest alternative authentication systems (more current). I have minimal expertise in system security and I'm worried about how to protect user credentials while maintaining a high level of response speed. </p>
