title: How to verify users current password?
body: <p>So, maybe I missed this somewhere in the docs but I couldn't find anything of the sort. </p>
  
  <p>I wan't my users to have to type in their current password to be able to create a new one. From what I understand if the user is authenticated he is able to update his password without providing his current one. </p>
  
  <p>Even if this might be somewhat secure I would rather have him type his old one to prevent people from going on already authenticated sessions from say family members or so and changing the pw. </p>
  
  <p>Is there any way to do this?</p>
  
  <p>(I have no problem using the Admin SDK since I already set up a server for these kind of things)</p>
