What is an OTP? Understanding One-Time Passwords

An OTP (One-Time Password) is a unique, temporary code used to enhance security during online authentication processes. Unlike traditional passwords, OTPs are valid for only a short period and can only be used once, making them a more secure option for preventing unauthorized access. OTPs are typically sent via SMS, email, or generated by an authenticator app. They are commonly used in two-factor authentication (2FA), providing an extra layer of protection for sensitive accounts and transactions. By using OTPs, users can significantly reduce the risk of cyber threats, such as phishing, identity theft, and data breaches.
