• signInWithEmailAndPassword():

Asynchronously signs in using an email and password. Fails with an error if the email address and password do not match.

• onAuthStateChanged():

Adds an observer for changes to the user's sign-in state.

• signOut():

Signs out the current user.

You can listen to a document with the onSnapshot() method. An initial call using the callback you provide creates a document snapshot immediately with the current contents of the single document. Then, each time the contents change, another call updates the document snapshot.
