title: Firebase Authentication : how to get current user's Password?
body: <p>i'm new to <strong>firebase Authentication</strong>.. so, i'm creating a basic app with a profile, i've made an activity to edit basic informations of the user such as <code>DisplayName</code> and <code>Email</code>... , i wan't to add the capability of changing passwords, but first , i wan't to check current user's password and compare it to a <code>String</code> from an <code>InputEditText</code> that the user must know his current password before changing it.</p>
  
  <p>EDIT : 
  the thing i'm asking about is i ask the user to write his current <code>Password</code> in order to be able to change it to a new one to reduce hacking or something like that, like on <code>Facebook</code> when you're trying to change the <code>Email</code> or <code>Password</code> or even the <code>Name</code> it asks you for your current <code>Password</code>.</p>
