fetchSignInMethodsForEmail equivalent ?

Hi !
Hope you are having a great day !

Is there a way to know if a user registered via email or any other oauth providers ?

The problem:

If the user registered first with google and try to connect using email and password he only get a wrong password error.
I would like to inform the user that he need to use google login.

Is there a way to create a similar function like the firebase one (fetchSignInMethodsForEmail) ?

Even when the user is signed up using Google that user can still use the email login option.
Meaning if you have

• Email login
• Google login
• Facebook login
  Any matched email will use to access the same account.

As of now there's no way to know how the account was opened/created.
The best workaround would be to display some message like:

Email & password are incorrect, try to reset your password or login with Google

I understand
Thanks for your fast reply !
So you don't think there is a hacky way to provide this functionality ?

Let me check something

I've went over it again
And the data of the user in the Database is the same, it doesn't seems like there's a way as of now to spot the user creation process.

Let's wait for Steven response on the one.

Ok thanks for checking !
I will migrate the rest of my app for now
