1 Choose an SMS API provider
Select a trusted provider that offers true global reach and sender ID functionality such as LINK Mobility.
2 Generate and store the OTP
Your application creates a unique, time-sensitive OTP, for example a six-digit code. Store it securely on your server together with its expiry time for validation when the user enters it.
3 Send the OTP through the SMS API
Use LINK Mobility’s SMS API to send the OTP to the user’s mobile number.
Include the phone number and OTP in your request and authenticate it with your API credentials. LINK Mobility then delivers the message through direct, high-quality routes.
4 Verify the OTP
When the user enters the received code, your system compares it with the stored OTP. If the code matches and is valid, the verification is confirmed and secure access is granted.
This simple process combines your authentication system with LINK Mobility’s powerful delivery network, creating a consistent and secure verification experience for users in every market.
Global OTP in Practice
