Once the installation is completed, open [http://localhost:80](http://localhost:80) to complete the [setup wizard](#setup-wizard).
:::note
- If installed on a remote device, make sure to replace `localhost` with your server's remote address.
- If installed with a custom port, make sure to replace `80` with the custom port.

:::warning
Make sure that you have configured a **firewall** and it's not blocking connection to the desired ports.
- [How to setup a firewall using UFW](../tutorials/setup-a-firewall-using-ufw.md)
LibreTime requires the following ports to be open:
-`80` for the web interface,
-`8000` for the Icecast streams,
-`8001` and `8002` for the live stream input endpoint.
Consider putting your installation behind a [reverse proxy](./reverse-proxy.md) to increase the security.

#### Using hardware audio output
If you plan to output analog audio directly to a mixing console or transmitter, the user running LibreTime (by default `www-data`) needs to be added to the `audio` user group using the command below:
```bash
sudo adduser www-data audio
```
### Setup wizard
The setup wizard walk you through the rest of the installation process.
#### Changing default passwords
It's recommended that you change the passwords prompted in the setup wizard. Be sure to apply the changes on the server before going to any next step.

```bash
sudo -u postgres psql -c "ALTER USER airtime PASSWORD 'new-password';"
```
