Password protected pdf won't open even with correct password

Hi @DexAlpenglow:

I wonder if the file was corrupted? You might want to encourage your co-worker to add markups using the free Adobe Reader and avoid Preview and other third party apps in the future. The Adobe apps were designed to work together. https://get.adobe.com/reader/

Why did you password-protect it in the first place? I hate to sound cold but this is just another reason not to bother with PDF security. It doesn't work anyway as there are way too many ways around it.

The answer here is to simply create a new version from the original InDesign document.

Hi @DexAlpenglow:

We've all been told that third party apps can bypass the password but I have never tried it myself. My understanding is that it depends on the encryption level. You might want to start here: https://smallpdf.com/unlock-pdf.
