Two Ways To Password-Protect Files On Your Mac

If you need to encrypt some files so the only way to acess them would be with a password, you can use one of two methods. By using Disk Utility you can create read/write disk images that can be opened on any Mac. But if you need to send some files to another person, you may want to instead use the Terminal to create an encrypted ZIP achive that will work on Windows as well.

    If you use the option to “Remember my password in my keychain” you may find it easy to Forget the password, because you can now open it (on this Mac) without needed to remember the password. So, I suggest immediately creating a TEXT file in that folder that saves the Password! If you email the folder they cannot see the TEXT file, but when they tell you “Hey, what’s the Password?”, you can re-open the folder (on your Mac), open the file, and tell them – but verbally, don’t email it! ;-)

    Mark: There’s no need to save your passwords that way. You can just view them in Safari (or Keychain Access) when you need them. They are encrypted in there.

    Great video. Knew about the .dmg file; not about how to encrypt a .zip file.
    I am tutoring some seniors, folks in their 70’s and 80’s and trying to get them to securely store their passwords. Both your methods would be beyond their abilities, even with me walking them, slowly, through every step.
    OTOH, creating a Note in Note.apps, from what I could find online, IF they chose a very strong password is almost as good a method as the methods you suggest in your video? You agree/disagree?.

    Bob: For passwords I would just use the built-in function in Safari (Keychain).
