Pages, Presentation, and Numbers are the main office applications for macOS.

Protecting files and folders using an encrypted disk image.

All of the major office suites support this to some degree and we’ll focus on the following in this article. In all of these cases, adding password protection to your documents and folders will help secure them. Some of us may also need to pass documents to through an untrusted medium such as the internet. Even if your computer is password protected, there may be situations when someone else has to use it and you’d prefer to limit their access to your personal files like budget spreadsheets and personal journals. Then it is encrypted along with your passwords.There are times when you want some extra protection for your documents on your Mac. The Pages method is much better.Īnother option is to use the Notes app, which can have locked notes.Īlso note that it is common for people who use third-party password managers like 1Password to simply create 'note' entries in their password databases with various pieces of information.

But that also involves many steps to open the Disk Image, then view/edit the file, then close the Disk Image.

You can also create an encrypted Disk Image to hold the TextEdit file. Then if you make changes you'd need to zip uo the new changed file and delete the old zip file. But then when you want to view the file again you basically have to unzip it, saving a copy of the file you can view. You can save the file as a zip file using encryption. If you really want to stick with TextEdit, it becomes more difficult to do. But if you put the file somewhere else, say on an external drive, and someone takes that drive and tries to open it, they wouldn't have the password. So while you are logged into your account on your Mac, you can open and close the file normally. You even get the option to save the password to your keychain. It actually encrypts the file, so it isn't just a lock, but real protection. Just go to File, Set Password and then you'll need a password to open the file again. Pages has a built-in password protection function. The best way to do this is to use Pages instead of TextEdit.
