What happens if I forget the password?

There's no recovery option — anyone without the password, including you, won't be able to open the file. Keep it somewhere safe.

Will this work with any PDF reader?

Yes. The password protection uses a standard encryption format supported by virtually all PDF readers.

You can re-open it with Unlock PDF using the same password whenever you need to edit it, then protect it again afterward.
