I’ll add a basic info for @TheTwelveYearOld@lemmy.world: every service MUST have a different password (password manager almost mandatory with a VERY strong password and 2FA). If you’re paranoid like me ( 🙈 ) use a different email alias for each service (SimpleLogin)

It would be nice to read the basic points of your statement, then if someone wants to go in detail, there’s the link to your article.
