Please help if you can integrate into my code these two things that I need. 1. I need to integrate the authentication or statement of email and password in the login with the existing ones in the database, and also the bcrypt. 2. I need to create a statement in which it says that if the email already exists in the database, go to login and otherwise complete the registration
