OTP means “one-time password.” It is a temporary code used to verify your identity when you log in, make a payment, or complete another secure action.
People usually receive an OTP by text message, email, or an app. They enter the code right away to prove it is really them, and the code stops working after a short time.
Meaning & Usage
An OTP is used for extra security. It helps protect accounts and transactions by adding a code that changes each time and cannot be reused.

You may get an OTP when signing in to WhatsApp, confirming a bank transfer, or resetting a password.
