SMSGatewayCenter offers two ways to handle one-time passwords (OTPs) for your business: OTP SMS and Integrated OTP SMS. While both deliver OTPs to users, they differ significantly in how they’re managed, giving you flexibility based on your needs. Here’s a breakdown of the key differences:
OTP SMS: #
- How It Works: With regular OTP SMS, you use our standard Send SMS API to deliver an OTP. However, you are responsible for generating the OTP code and verifying it on your own system. SMSGatewayCenter’s role is limited to sending the message—we don’t create or validate the OTP for you.
- Your Responsibility:
- Generate a unique OTP on your server or application.
- Send it via our API.
- Verify the user-entered OTP on your end.
- Best For: Businesses or developers who want full control over OTP logic and already have a system in place to handle generation and verification.
Integrated OTP SMS: #
- How It Works: Integrated OTP SMS is a premium, all-in-one solution where SMSGatewayCenter takes care of everything—generating the OTP, sending it, and verifying it at our server level. You simply integrate our Generate OTP API and Verify OTP API into your app or website.
- Our Responsibility:
- Automatically generates a secure OTP.
- Delivers it to the user (with SMS or voice backup).
- Verifies the OTP when the user submits it.
- Best For: Those seeking a quick, hassle-free setup with minimal coding, plus added features like logs and 100% delivery assurance.
