What Is OTP Verification?
One-time password (OTP) verification is a security process that uses a one-time password to confirm a user’s identity during login or transactions. The user receives a temporary code via SMS or messaging apps like WhatsApp.
OTPs are valid for a short time and can only be used once, adding an extra layer of protection beyond passwords.

Got Questions? We’ve Got Answers.
Why is OTP verification important?
OTP verification adds an important layer of security by confirming that the person accessing an account or completing a transaction is the legitimate user. It reduces the risk of fraud, identity theft, and unauthorized access, especially in systems that store sensitive data.
How do I use an OTP verification service?
To use an OTP service, integrate Dexatel’s API into your platform or application. The system will then generate and send one-time codes to users during login, registration, or transaction steps. You can monitor delivery and performance through the dashboard and enable fallback channels to boost reliability.
How long are OTP codes valid for?
OTP codes are typically valid for one to five minutes, depending on how sensitive the transaction is. Shorter validity windows minimize the risk of interception or unauthorized use. Dexatel allows you to customize OTP expiration settings to match your platform’s security requirements.
