An OTP (One-Time Password) call is an automated phone call that delivers a unique password to verify a user’s identity. It is commonly used for secure login, account verification, and online transactions. Unlike traditional passwords, OTPs are temporary and valid for a short period, reducing the risk of fraud and unauthorized access.

When a user initiates a verification process, the system generates a unique OTP and delivers it through a voice call. The user listens to the OTP and enters it on the required platform to complete authentication. This method ensures security by adding an extra layer of protection beyond just usernames and passwords.
Businesses use OTP calls for various purposes, including account sign-ups, transaction approvals, password resets, and reactivating services. It is also useful for verifying third-party access, such as delivery personnel entering gated communities.br>
OTP calls are reliable, work on both smartphones and basic mobile phones, and do not require an internet connection. Other ways to receive OTPs include SMS, email, and push notifications. As a widely used security measure, OTP calls help prevent fraud and unauthorized access, ensuring a seamless and protected user experience.
