OpenTekHub/otpauthentication

AI Summary: Integrate a PostgreSQL database into an existing FastAPI and Twilio OTP authentication system to store user phone numbers. This involves setting up database connection, creating a user model, modifying the authentication flow to persist user data, and potentially adding database migration capabilities.

AI Summary: Implement rate limiting for the SMS OTP authentication service. Consider using in-memory storage, a database, or Redis to track the last OTP send time for each user to prevent abuse. Choose the most appropriate storage mechanism based on project scalability needs.

AI Summary: Create a requirements.txt file listing all Python packages needed for the FastAPI and Twilio OTP authentication project. This file will allow others to easily reproduce the project's environment by running `pip install -r requirements.txt`.

AI Summary: Add an open-source license (e.g., MIT, Apache 2.0, GPLv3) to the OTP authentication project repository. This involves choosing a suitable license from choosealicense.com and adding the corresponding license file to the repository.

AI Summary: Redesign and expand the README.md file for a FastAPI and Twilio OTP authentication project. The updated README should include a project overview, detailed feature list, installation instructions, usage guide, contribution guidelines, license, and acknowledgments. Screenshots or a demo link would be beneficial.
