How to protect yourself from iCloud hack?

Question

Burglary protection

Happy holidays, I have a question. Recently, more and more often I hear stories about iCloud hacking and blocking all devices, followed by extortion of money. Tell me how to protect yourself? Other than how to disconnect from iCloud, nothing comes to mind. I also heard about "two-step authorization by linking a phone number", but I did not find such a function in the iCloud settings.

Answer 1

How do I set up two-step verification?

Answer 2

Well, firstly, after the autumn leak of photos, messages now come to the main email when working from a new device.
Secondly, you can change passwords periodically.
Well, as for blocking with extortion, as far as I remember, there were interesting people who bought or received ready-made accounts with a large number of games from scammers for free, and used them, and then they all disappeared.
Well, in principle, last year, Apple closed like 2 vulnerabilities with brute force icloud passwords, but I don’t think that it was possible to merge a lot through them en masse. For cracking celebrity passwords, this is an option, but for ordinary users, it was most likely passwords leaked by thrones on computers, etc.
