Sinch provides a strong
Missed Call Verification service that allows businesses to authenticate users quickly and securely. The service triggers an automated verification process when a user initiates a missed call to a designated number. Upon receiving the missed call, an OTP or verification code is sent to the user's mobile via SMS or voice to confirm their identity. This method is quite effective for user authentication, account verification, and secure transactions. Through Sinch's Missed Call Verification service, businesses can be assured of easy, inexpensive, and secure validation of the users, thereby elevating overall customer experience and trust.
