# Connectivity and Access management

> Configure the Core API's ports, hostnames, and authentication for LAN and HTTPS access.

As mentioned in the **Local Server Applications** documentation {/* TODO unresolved link: 1d199c26bb2743d581d0023e23cbcbd2 */} the Core server runs by default on port `3002` allowing remote access over the LAN by all NIC's via host `0.0.0.0`
The Advanced Core Settings do allow you to set custom ports and hostnames to have more gradual control over the Core API network access.

## Authentication

Most endpoints of the Local API are secured with authentication.
Click on the **Generate Token** button in the \*\*Cloud Core Settings \*\*to generate an username and password for accessing the API.
The authentication method is "Basic Authentication" and you can authorize yourself with the `EXTERNAL_APP`  username via the `Authorization`  header:

```javascript theme={null}
Basic {base64([username]:[password]}
```
