+### Password protected
+
+To open a password-protected PDF document, set the <code>Password</code> parameter to the required password.
+
+<img src="" alt="Blazor Bootstrap: Blazor PDF Viewer Component - Password protected" />
+
+```cshtml {} showLineNumbers
+<PdfViewer Class="mb-3"
+           Url="@($"{StringConstants.DocsBasePath}/pdf_password_protected.pdf")"
+           Password="12345" />
+```

+
+### Prompt for password
+
+If the <code>Password</code> parameter is not set and the PDF document is password-protected, the PDF Viewer component will prompt the user to enter the password.
+In the following example, the PDF Viewer prompts the user to enter the password for the protected PDF document. Enter <b>12345</b> as the password to view the document.
+
+<img src="" alt="Blazor Bootstrap: Blazor PDF Viewer Component - Prompt for password" />
+
+```cshtml {} showLineNumbers
