Supported Scenario: If a user initially signed up with an email and password, they can later log in using a social login method, such as Google. In this case, the account is merged, and the user can log in using either method.

Not Supported Scenario: If a user initially signed up using a social login method (e.g., Google), they cannot later switch to using an email and password. The login attempt with email and password will fail, and password reset emails will not be delivered. Users in this situation are advised to continue using the original social login method.
