Microsoft Edge offers built-in support for viewing PDF files that are classified and protected. Microsoft Edge can enable you to open protected PDF files without the need to install or configure any additional apps.
If you are attempting to view a protected file that is not a PDF (for example, it has a .pfile file name extension), you may want to use one of the Microsoft Purview Information Protection viewers. See View protected files with the Microsoft Purview Information Protection viewer for more information.
