Sending OTPs (One-Time Passwords) is a simple yet powerful way to improve security. This process involves generating and sending a unique, time-sensitive code to a user's mobile number or email using the Send OTP method. The user must enter this code to verify their identity, ensuring that only authorized individuals can access sensitive information or complete transactions. By implementing Send OTP, you can significantly enhance your authentication process, reduce the risk of fraud, and protect user data.
