OTP SMS (One-Time Password via Short Message Service) is a secure authentication method that sends a unique, time-sensitive code to a user's mobile phone to verify their identity during login or transaction processes.

OTP SMS adds an extra layer of security by requiring users to enter a dynamic code received via SMS. This mitigates the risk of unauthorized access, especially in online banking, e-commerce, and other sensitive applications.

The one-time password is dynamic, valid for a short period. This enhances security, as even if intercepted, the code becomes useless after expiration, reducing the risk of unauthorized access.

OTP SMS is widely used in various industries for user authentication, including online banking, e-commerce, healthcare, and more. It ensures secure access to accounts and protects sensitive information.

While contributing to enhanced security, OTP SMS aims to maintain a user-friendly experience. It provides a quick and straightforward method for users to confirm their identity without the need for complex authentication processes.
