Here are two important things to do in order to have your digital stuff secure:

• Do backups! Honestly I don't get how some people go about their lives without having their stuff backed-up. You can so easily delete your digital stuff and never recover it.
• Enable Two Factor authentication for all of the important websites you use. I use KeePassXC that also has this capability.

And use Linux. forget about Mac or Windows :D. Linux is really awesome. Try TROMjaro.com - we made it very easy to use and secure and trade-free. No ads in the browser, no data collection + a VPN integrated. #tromlive
