Encrypt your hard drive in case your PC is ever lost or stolen

Losing your computer can be as bad as losing your wallet or purse, since it probably contains a lot of extractable personal information, including financial details. Disk encryption eliminates this risk by making all data on your hard drive inaccessible to anyone without a specific key (password). Use FileVault on macOS or BitLocker on Windows to get started, but be sure to remember your key.
