How does the MacBook know all my passwords?

Question

macOS

It's not clear how, but the MacBook knows all my passwords from the Chrome browser, which I have on another computer in general. And it’s also protected by a passphrase, which I DEFINITELY didn’t write on a macbook.
When you enter the site, it asks "Safari wants to get your data from the keychain" and still gets it. These passwords on the MacBook were never even entered.
There is an assumption that this is somehow connected with Google accounts or something like that. I also have an iPhone and there I also did not enter all these passwords.
So how did it know all of mine? Of course, I like that it did everything so conveniently, but I want to understand HOW it did it.

Answer 1

Chrome syncs passwords and bookmarks if you're logged in.
Apparently on a safari poppy, it loaded everything from it, filled it in a bunch - from there the iphone received the data.
In general, I tried it now - I could not reproduce it.
Passwords from chrome separately, bundled separately :(

Answer 2

This is Apple. Everything is done for the user. I have the same problem, I don't understand how it happened

Answer 3

if you have all the passwords in chrome, it is logical that he just took them from chrome
