# Host and port information

To change the default IDM hostname or listening ports, edit the applicable entry in `openidm/resolver/boot.properties`:

```none
openidm.port.http=8080
openidm.port.https=8443
openidm.port.mutualauth=8444
openidm.host=localhost

openidm.auth.clientauthonlyports=8444
```

* `8080`

  HTTP access to the REST API, requiring IDM authentication. This port is not secure, exposing clear text passwords and all data that is not encrypted. This port is therefore not suitable for production use.

* `8443`

  HTTPS access to the REST API, requiring IDM authentication

* `8444`

  HTTPS access to the REST API, requiring SSL mutual authentication. Clients that present certificates found in the truststore (`openidm/security/`) are granted access to the system.
