# Welcome

BlitzWare is an authentication platform for products that need secure user login, token issuance, application controls, and operational visibility.

BlitzWare supports two Application models:

| Application model | Best for                                                                                | Authentication style                                                      |
| ----------------- | --------------------------------------------------------------------------------------- | ------------------------------------------------------------------------- |
| Basic Application | Direct API-driven login, desktop clients, lightweight product auth, license-aware apps. | Your client or backend calls BlitzWare HTTP APIs directly.                |
| OAuth Application | Web, SPA, mobile, and backend integrations that need OAuth 2.0 authorization flows.     | Users authenticate through redirect-based flows and receive OAuth Tokens. |

{% hint style="info" %}
Start with [Choosing Between OAuth and Basic Applications](/core-platform/choosing-between-oauth-and-basic.md) if you are not sure which Application model fits your product.
