title: Cross-browser techniques for disabling password caching
body: <p>Saving and auto-filing of username/password is a feature of most modern browsers. And the user can generally choose to disable this feature on a per domain basis. But is there a standard way for the site itself to prevent password caching?</p>
  
  <p>The emphasis here is cross-browser, so I would employ multiple parallel mechanisms if necessary.</p>
  
  <p>(I have seen caching be effectively disabled in the presence of non-standard login fields, eg, an extra hidden password field. But I'd rather not depend on <em>side-effects</em> whose behavior could unexpectedly change in the future.)</p>
  
  <p>Conversely, are there browsers/versions out there that implement password caching without any disable feature?</p>
