User is re-logged in upon setting a new password
Sure, just looking at the docs: https://docs.angularjs.org/api/ngResource/service/$resource It seems that the `user.$update` function takes a success callback. So you could do something like:

```javascript
user.$update(function (user, responseHeaders) {
  // the success processing: see if the user parameter now has email and password. 
});

```
