The following C# code example explains the process, so let’s get started with it.

• Initiate an object of the HtmlViewOptions class.
• Set a password using the LoadOptions.Password property.
• Display the protected document using the View method.

// Set a password.
LoadOptions loadOptions = new LoadOptions();
loadOptions.Password = "000123";
// Render the protected file.
using (Viewer viewer = new Viewer("protected.docx", loadOptions))
{
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
    viewer.View(viewOptions);
}
