To authenticate itself to the ACS? Or for the ACS to authenticate itself to the CPE?

Here is the default inform provision. It sets the username/password for ACS to CPE authentication.

```auto
// Device ID as user name
const username = declare("DeviceID.ID", {value: 1}).value[0]

// Password will be fixed for a given device because Math.random() is seeded with device ID by default.
const password = Math.trunc(Math.random() * Number.MAX_SAFE_INTEGER).toString(36);

const informInterval = 300;

// Refresh values daily
const daily = Date.now(86400000);

// Unique inform offset per device for better load distribution
const informTime = daily % 86400000;

declare("InternetGatewayDevice.ManagementServer.ConnectionRequestUsername", {value: daily}, {value: username});
declare("InternetGatewayDevice.ManagementServer.ConnectionRequestPassword", {value: daily}, {value: password});
declare("InternetGatewayDevice.ManagementServer.PeriodicInformEnable", {value: daily}, {value: true});
declare("InternetGatewayDevice.ManagementServer.PeriodicInformInterval", {value: daily}, {value: informInterval});
declare("InternetGatewayDevice.ManagementServer.PeriodicInformTime", {value: daily}, {value: informTime});

declare("Device.ManagementServer.ConnectionRequestUsername", {value: daily}, {value: username});
declare("Device.ManagementServer.ConnectionRequestPassword", {value: daily}, {value: password});
declare("Device.ManagementServer.PeriodicInformEnable", {value: daily}, {value: true});
declare("Device.ManagementServer.PeriodicInformInterval", {value: daily}, {value: informInterval});
declare("Device.ManagementServer.PeriodicInformTime", {value: daily}, {value: informTime});

```
