signInWithEmailAndPassword and EmailAuthProvider

I am trying to understand the new authentication model. I am trying to convert web code that used the older authWithPassword.

Considering I had:

firebase.authWithPassword({email: email, password: password }).then(
authData => console.log('auth: authWithPassword success '+authData.uid),
err => console.log('auth: authWithPassword fail: '+err));

How do I achieve the same thing with the new version ?

There seem to be two different interfaces:




but I don't understand the difference or how to use them. Is there any clear example for the correct way to do email authentication ?

There are a lot of such differences with the new API. Best to stick closely to the docs.

The new docs site has a guide on email/password authentication, but to your specific question about the code:

firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
