EPFO Login Page Performance and OTP Verification Issues

I recently developed an EPFO-related login portal and noticed several issues affecting the user experience during authentication and account access.

Users are reporting slow page loading, delayed OTP verification, and occasional session timeout problems while trying to log in using their UAN credentials. In some cases, the login button becomes unresponsive on mobile devices.

Expected Behavior
Fast and responsive login page
OTP delivered quickly without delays
Smooth login process on both desktop and mobile
Stable session handling without unexpected logouts
Current Behavior
OTP verification sometimes takes too long
Login page performance decreases during high traffic
Mobile responsiveness issues on smaller screens
Occasional server timeout errors
Steps to Reproduce
Open the EPFO login page
Enter UAN and password
Request OTP verification
Wait for the response or attempt login on mobile
Suggested Improvements
Optimize API response times
Improve mobile responsiveness
Add better error handling for OTP failures
Implement caching and performance optimization
Enhance session stability for active users
Additional Notes

This issue mainly affects users accessing PF balance, claim status, and UAN-related services. Improving login reliability would significantly enhance the overall user experience.

No repository file, test, or entry point is identified. The report describes an external EPFO login portal and combines performance, OTP, mobile, and session concerns; clarify the affected project and a specific reproducible failure before implementation, with the relevant code and test location identified.
