OTP SMS

OTP, or One-Time Password, SMS is a short message that contains a one-time auto-generated password that is sent to the user who initiated the request’s registered mobile phone number. This technique is likely the most widely utilised approach by businesses all over the world to ensure that a login request has been generated by a legitimate person. The OTP SMS service is incredibly simple to use.

OTP SMS is delivered to users’ mobile phones as soon as they submit their username and password to log in.This SMS contains a code, usually four to six digits long and only good for one usage, which users must enter as quickly as possible (in most situations, the OTP expires within a minute and the user must generate a new one) into the provided space in order to continue with the login. This ensures that the individual login into his or her account has been given permission to do so by the account holder.
