## Quick start
When first launching the app you will be presented with Quick start screen asking you to provide your Home Assistant url and [device name](/help/mobile_app_integration#device-name) for [Mobile App integration](/help/mobile_app_integration).

You can just copy your Home Assistant url from browser and use it in the app:

The easy and secure way to aceess you Home Assistant from anywhere (not only from your local network at home) is [Remote UI](https://www.nabucasa.com/config/remote/). If you alredy had it set up, just open your Home Assistant UI in browser, go to **Configuration** - **Home Assistant Cloud**, find **Remote Control** section and copy the url from **Your instance is available at**.

Now you need to login. And this process will be almost automatic thanks to [Home Assistant Authentication API](https://developers.home-assistant.io/docs/en/auth_api.html). You'll see a login form loaded directly from your Home Assistant instance:

That's it! You are ready to go.

## Advanced
### SSL Certificates
The main requirement is that your SSL Certificate should not be self-signed. Most certificates from providers like Let’s Encrypt will work. There is [known issue](https://github.com/estevez-dev/ha_client_pub/issues/24) with RapidSSL certificate, but this problem is common not only for HA Client.

Using of self-signed certificate is not possible for now and this is a restriction of Flutter’s WebSocket implementation.

### Login with long-lived token
It is possible to generate long-lived token manually and set the app to use it instead of logging in with a simple OAuth way.
To make HA Client use your generated long-lived token you need:
1. Go to your Home Assistant web interface and open your profile settings (just click on your user picture in the bottom part of main menu)

2. Scroll down to **Long-lived access tokens** section and click **Create token**

3. Give it a name `HA Client` as it will be used only for HA Client app (it is recommended to use different access tokens for different apps and services)
4. Click **Ok** and copy newly generated access token somewhere in a safe place or directly to **HA Client**:
