Hi there,
We do not have an API to detect if a document is password protected. You could programatically add the password into the [loadDocument](https://pdfjs.express/api/UI.html#.loadDocument__anchor) API to open a password protected document.
You can also use the loaderror event to handle if the document fails to load:
> **[PDF.js Express Viewer Events | Documentation](https://pdfjs.express/documentation/learn-more/events.8#document-load-error-handling)**
And then use a custom modal to display your message:
