title: AOG implicit account linking - How to reset?
body: <p>I have setup an implicit account linking page. I tested it with AOG - all good, surface checked, user sent over to the phone app if needed, link worked (status OK, accessToken present). </p>
  
  <p>Now I can't figure out how to reset the user id or the account linking status to repeat this. It's not just testing. The user could need a new token for many other reasons. </p>
  
  <p>Currently if I initiate a subsequent SING_IN it comes back immediately with an OK and the accessToken. </p>
