title: Forget which client certificate is used by Chrome for an URL
body: <p>I'm using a client certificate to authenticate with HTTPS to a website. 
  The first time, chrome asked me which certificate I wanted to use.
  However, I don't how to flush/forget this choice to choose another certificate. Chrome remembers it and I didn't find (either in stackoverflow or chrome settings) a solution to that.</p>
  
  <p>The only way I found is to open a new window in private mode.</p>
  
  <p>Anyone know how to do it ?</p>
