# What is the difference between Integrated Security = True and Integrated Security = SSPI?

What is the [difference](https://www.mindstick.com/articles/157114/good-news-or-bad-news-and-the-difference-is) between [Integrated](https://www.mindstick.com/forum/33532/handler-pagehandlerfactory-integrated-has-a-bad-module-managedpipelinehandler-in-its-module-list) [Security](https://www.mindstick.com/articles/43813/new-security-technologies) = [True](https://yourviews.mindstick.com/view/81326/boycott-chinese-products-dream-will-come-true) and Integrated Security = SSPI?

Sure, I can help you with that.

The `integrated security = true` and `integrated security = SSPI` options in a connection string specify how a .NET application will authenticate to a database.

- **integrated security = true** uses Windows Integrated Authentication (WIA) to authenticate the user. WIA uses the user's Windows credentials to authenticate them to the database.
- **integrated security = SSPI** uses Security Support Provider Interface (SSPI) to authenticate the user. SSPI is a more generic authentication mechanism that can be used to authenticate users to a variety of resources, including databases.

The main difference between the two options is that **integrated security = true** is specifically designed for Windows systems, while **integrated security = SSPI** can be used on any system that supports SSPI.

Here is a table that summarizes the key differences between `integrated security = true` and `integrated security = SSPI`:

| Feature | integrated security = true | integrated security = SSPI |
| --- | --- | --- |
| Authentication mechanism | Windows Integrated Authentication (WIA) | Security Support Provider Interface (SSPI) |
| Supported platforms | Windows | Any platform that supports SSPI |
| Ease of use | Easier to use | More complex to configure |
| Security | More secure | Less secure |

In general, you should use `integrated security = true` if you are developing a .NET application for Windows systems. You should use `integrated security = SSPI` if you are developing a .NET application for non-Windows systems or if you need more control over the authentication process.
