 > - The `create` method simply checks if the user exists and is confirmed. If they are, then we check their password. If the password is correct, we log them in via the `login` method we created in the `Authentication` Concern. Otherwise, we render an alert.
 >   - We're able to call `user.authenticate` because of [has_secure_password](https://api.rubyonrails.org/classes/ActiveModel/SecurePassword/ClassMethods.html#method-i-has_secure_password)
 >   - Note that we call `downcase` on the email to account for case sensitivity when searching.
+>   - Note that we set the flash to "Incorrect email or password." if the user is unconfirmed. This prevents leaking email addresses.
 > - The `destroy` method simply calls the `logout` method we created in the `Authentication` Concern.
 > - The login form is passed a `scope: :user` option so that the params are namespaced as `params[:user][:some_value]`. This is not required, but it helps keep things organized.
