I found out this year that Europe and US don't do time changes at the same time - not really a surprise, but I never thought about it before, and it makes it even harder to guess which "good X" to use :)
If you could give 5 tips to non-security people, what would it be?
Mine would be:
1.) Keep everything updated 2.) Make regular backups on external hardware 3.) Use a password manager 4.) Use 2FA where available 5.) Don't download things from untrustworthy sources
