### Description

Specifies a password for the document's access permissions. If the password is an empty string, accessing the document is not restricted. If a password is specified, the access permissions are given through the [SaveSettings.DocumentAccessPermissions](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/savesettings/documentaccesspermissions-property/llms-full.txt) property.

### Syntax

```csharp
public string MasterPassword { get; set; }
```

```vbnet
Public Property MasterPassword As String
```

### Examples

```csharp
loadSaveSettingsBase.MasterPassword = documentPassword;
if (loadSaveSettingsBase is LoadSettings loadSettings)
{
    textControl.Load("template.docx", StreamType.WordprocessingML, loadSettings);
}
else if (loadSaveSettingsBase is SaveSettings saveSettings)
{
    textControl.Save("configured-document.docx", StreamType.WordprocessingML, saveSettings);
}
```

```vbnet
loadSaveSettingsBase.MasterPassword = documentPassword
If TypeOf loadSaveSettingsBase Is LoadSettings Then
    textControl.Load("template.docx", StreamType.WordprocessingML, DirectCast(loadSaveSettingsBase, LoadSettings))
ElseIf TypeOf loadSaveSettingsBase Is SaveSettings Then
    textControl.Save("configured-document.docx", StreamType.WordprocessingML, DirectCast(loadSaveSettingsBase, SaveSettings))
End If
```
