check if the user exists before logging in with oath2

User is asking why they should check if a user exists before logging in with OAuth2. They are concerned that it may allow bad actors to check if accounts exist on their app. They mention that they want to check if the user exists immediately because their app (Appwrite) automatically creates an account for the user. Solution: It is generally not recommended to have a feature that allows checking if accounts exist on your app before logging in with OAuth2. However, if you still want to implement this feature in Appwrite, you can modify the code to perform a check for user existence before creating a new account.
