There are existing users who login with their email or social accounts. How will existing users login if we get rid of social and email login?

As Nash says it is better for legacy users that you let them login with their old method but if you cant.
- You should invite your existing users to migrate to new form of login.
- Explain them why the change.
- Ask them to migrate their user.
- Notify them the confirmation of the new way for login.
But as I say. The better is to let the two ways available.
Your options are:
- Keep email and social login option for legacy users: Don't allow them for new users, though.
- Notify old users via email or in the application of the migration: Tell the users that they need to change their login method until day X (This is also what a lot of banks have to do if they requirements for login change).
