title: Basic Authentication With Different Installs
body: <p>The app I am creating uses a phone number to authenticate. For the authentication we use</p>
  
  <p>phoneNumber:password for the basic authentication header. At the moment this same password is used for users on multiple devices.</p>
  
  <p>We now need to support multiple devices. So we are thinking of assigning a new password for each number.</p>
  
  <p>Does it make sense to do it this way? Should we have a UserId and user this on every installation regardless of the phonenumber? Should we have a new password for each installation/each user/each phone number? </p>
