🔐 OTP System with PHP & MySQL 💻

This project is an OTP (One-Time Password) System built with PHP and MySQL. It allows users to request an OTP for actions such as login, registration, or verification. The OTP is sent via email or SMS (depending on the implementation), ensuring secure and validated actions.

🌟 Features 🌟

• 📧 OTP Generation: Generates a unique OTP and sends it to the user’s registered email address.
• 🔑 OTP Validation: Validates the OTP entered by the user against the generated one.
• 📅 Expiry Time: OTPs have a set expiry time for added security.
• 🛡️ Secure Authentication: Ensures the authenticity of user actions (login, registration) using OTP.
• 🔒 Database Integration: MySQL stores OTPs and tracks their expiry time for validation.
• 🖥️ User Interface: A simple and user-friendly interface to request and verify OTPs.
