Google Forms OTP verification Using Firebase and JavaScript

I recently completed an exciting project where I integrated Google Forms OTP verification, Firebase Authentication, JavaScript, the IPAPI.co API, and Google Sheets to build a robust and user-friendly phone number verification system. This solution improved the user experience while simplifying data collection and management processes.

The aim was to build a secure phone number verification system with automated country code detection based on the user’s IP address, and to efficiently store and manage user data in Google Sheets. Here’s a detailed look at how these technologies were integrated:

Google Forms served as the primary interface for collecting user data:

User-Friendly Interface: Embedded Google Forms allowed users to input their details, including phone numbers and location data.

Form Customization: Tailored the form to collect necessary information and streamline the data entry process.

Firebase Authentication ensured a secure verification process:

Phone Number Verification: Utilized Firebase’s phone number authentication to verify user identities. This included using reCAPTCHA for security and handling OTP (One-Time Password) verification.

Error Management: Provided users with clear and actionable feedback in case of verification issues.

JavaScript was crucial for dynamic interactions within the form:

Dynamic Country Code: Used JavaScript to automatically set the initial country code in the phone number input field based on IP-based location data.

Form Submission Handling: Managed form submissions and user interactions effectively to ensure a smooth experience.

The IPAPI.co API provided location-based personalization:

Geolocation: Integrated IPAPI.co to detect the user’s country from their IP address. This information was used to automatically set the country code in the phone number input field.

Improved User Experience: Reduced manual input and errors by pre-filling the country code based on detected location.

Google Sheets was used to store and manage collected data efficiently:

Data Integration: Leveraged Google Sheets API to automatically store form responses in a Google Sheet. This facilitated easy access to and management of user data.

Real-Time Updates: Ensured that data entered through Google Forms was instantly reflected in the Google Sheet, providing real-time updates and data synchronization.
