title: Send password with JSON in a HTTP POST
body: <p>Is it safe to send a password with JSON in a HTTP POST from Android app?</p>
  
  <p>In database I have password hash and salt.</p>
  
  <p>Maybe better solution would be that user first sends his username to server, server returns him salt, then he makes hash in app and sends password hash to server.
  Is that safe? 
  Is there a better way to do it?</p>
