tl&dr: you should not put anything about you on the internet about you don’t want to see on the billboard in the city center.
The privacy on the internet is treated as one of the greatest concerns last year and it would be treated even more next year. There are lots of articles how to harden your smartphone, what to turn off in the Windows 10 or where to store secrets. I think that they’re missing some concepts:
- The secret itself is something you’re not telling anyone.
- The best protection you can give the information that compromises you are not having or keeping this information.
- Some entities you have to trust due to legal reasons, so trust them only on the level you can afford.
