What is OTP Authentication?
OTP (One-Time Password) is a unique, time-sensitive code sent to a user’s mobile or device for verification. It can only be used once and expires quickly, making it highly secure against unauthorized access.
It adds an extra layer of protection beyond passwords, commonly used in banking, apps, and online platforms.
