title: How to store password on gae properly when someone registers?
body: <p>For example:</p>
  
  <pre><code>username:zjm1126
  password:11
  </code></pre>
  
  <p>I store the password to the datastore on gae. When I see the data view at <code>/_ah/admin</code>, I can see the password of all people that have registered.</p>
  
  <p>Is it safe to do so? If not, how to store it properly?</p>
  
  <p>And the <code>check_password</code> method is:</p>
  
  <pre><code>user=MyUser.get_by_key_name(self.request.get('username'))
  if user.password == self.request.get('password'):
      session['user.key']=str(user.key())
  else:
      raise Exception('error 404')
  </code></pre>
