Allow both email-based and google-based auth

According to the docs here https://firebaseopensource.com/projects/firebase/firebaseui-web/:

You cannot use email/password and email/link sign-in at the same time. Only one mode can be configured at a time. However, if you previously signed up users with passwords. Switching to email/link will only apply to new users and existing password users will continue to be prompted for password on sign-in.

it seems wired to me that I can have both email-based authentication alongside the google auth, why is that? any way around it?
