Google OAuth Authentication with OTP Verification

This is a module to test and verify Google authentication for web applications, ensuring that only Gmail-confirmed accounts are able to authenticate and access services. This way, any random email addresses won't be verified without proper Gmail confirmation.

How does it work?

1. Created an API service in the Google Developer Console.
2. Implemented the API routes provided by Google in Flask.
3. Set up SMTP mailing configuration in Gmail to verify users via OTP.

How to use this module locally?
