# Authentication

Uiza APIs apply the [HTTP Basic Authentication Protocol](https://swagger.io/docs/specification/2-0/authentication/basic-authentication/), where the client sends HTTP requests with the API key in the Authorization header.

Once you have signed up, you can create applications (maximum of 2 applications) with an API Key assigned to each application. 

You can manage your applications and API Keys in the [Uiza Dashboard](https://id.uiza.io/).

All API requests to Uiza *must go* over HTTPS and include a valid API Key.
