----------------------------------------------------------------------------

If you want to develop a project to log in with OTP mobile Number in Spring Boot Applications then this post for you. In this post, I am going to use some other service to send the OTP in mobile number.

• we have to use it in this project spring boot.

• we are going to use Twilio to send SMS.

• we are going to use a web socket to send the data from the browser to the SMS gateway.

• Oracle Database for store the user details.
