Activities:
iPhone (beware of backing up to icloud)
OS X comes with software, File Vault 2, already installed on your computer that can do this hard-drive encryption for you. All you have to do is set it up according to Apple's instructions Windows 10 will encrypt your hard-drive by default, as detailed here. However, if you have an earlier version of Windows, you can use the software Bitlocker.
Make sure to remember your encryption password!
If you were to forget this, all of your computer's data would be irretrievably lost. It's also important to note that while hard drive encryption is a great deterrent for a casual thief or troll trying to physically access your computer, it would not be effective against a more sophisticated attacker (like a government tech force). If that is your concern, you'll want to manually encrypt your most important files with PGP.
If a participant is not ready to do this encryption, they can download VeraCrypt and encrypt a File Folder. Introductory VeraCrypt info here
