What Is OTP Verification?

OTP Verification is a security process that confirms a user's identity using a temporary One-Time Password. This code is generated automatically and is usually sent through SMS, email, or an authentication app.

Unlike traditional passwords, OTPs are valid for only one verification session and expire after a short period. This makes them much more difficult for attackers to reuse.

How OTP Verification Works

The verification process is simple but highly effective.

1. The user enters their username, email address, or phone number.
2. The user provides their password or starts account registration.
3. The website generates a unique OTP.
4. The OTP is sent to the registered phone number or email address.
5. The user enters the verification code.
6. If the code is correct, the requested action is completed.

This additional verification step helps ensure that only authorized users can access the account.

Why Websites Ask for OTP Verification
