# What’s the Difference Between OTP SMS and Integrated OTP SMS on SMS Gateway Center?

**SMSGatewayCenter** offers two ways to handle one-time passwords (OTPs) for your business: **[OTP SMS](https://www.smsgatewaycenter.com/otp-sms-india/)** and **[Integrated OTP SMS](https://www.smsgatewaycenter.com/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**](https://www.smsgatewaycenter.com/developer-api/send-sms-batch/) 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**](https://www.smsgatewaycenter.com/developer-api/generate-otp/) and [**Verify OTP API**](https://www.smsgatewaycenter.com/developer-api/verify-otp/) 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.

#### Key Differences at a Glance:

| Feature | OTP SMS | Integrated OTP SMS |
| --- | --- | --- |
| **OTP Generation** | You generate the OTP | We generate it for you |
| **OTP Verification** | You verify it on your system | We verify it on our servers |
| **API Used** | Send SMS API | Generate & Verify OTP APIs |
| **Effort Required** | More coding on your part | Minimal coding, fully managed |
| **Control Level** | Full control over logic | Streamlined, hands-off |

#### Which Should You Choose?

- **OTP SMS:** Ideal if you prefer customizing the OTP process and have the resources to manage it.
- **Integrated OTP SMS:** Perfect for saving time, reducing development effort, and leveraging our secure, server-side handling—our flagship solution!
