title: Mobile device: How to secure API credentials?
body: <p>I have an APi which requires a set of developers credentials  (consumer key/consumer password) in order to call  Register user web service to register a user.</p>
  
  <p>I would like to call the register user web service method via a mobile device, but do not want to store the developers credentials (too dangerous, even if its encrypted)</p>
  
  <p>how would you solve this problem?</p>
