Express Auth Starter Template

This is a complete authentication system that can be used as a starter code for creating any new express application. It includes sign up, sign in, sign out, reset password, and social authentication using Google. Additionally, it also includes a bonus feature of forgot password functionality. The code is well-commented for easy understanding and scalability. The folder structure is separate for models, controllers, and routes, making it easy to scale the project. This code can serve as a boilerplate for any Express application that requires a basic authentication module.

Functionality

• Sign Up Users can sign up using their email. The password is encrypted and stored in the database. If the passwords do not match, an error message is displayed. Re-captcha is enabled on the sign-up page.
• Sign In Users can sign in using their email and password. If the email and password are incorrect, an error message is displayed. After sign-in, the user is redirected to a blank home page with sign-out and reset password buttons. Re-captcha is enabled on the sign-in page.
• Sign Out Users can sign out of their account using the sign-out button on the home page.
• Reset Password Users can reset their password after signing in. If the user forgets their password, they can reset it using the forgot password feature. A random password can be generated and sent via email, or a reset password link can be sent, which expires after some time.
• Social Authentication Users can sign up and sign in using their Google account.
