Two factory authentication

[myname70]

Guys, I activated two factory authentication because of the autounlock iMac via my Apple Watch. And now, every time when I log in to my Apple ID (on the iPhone safari or iMac safari etc) it asks me for the verification code. And the code is sent and supposed on the same devise screen so, no sense at all to ask to verify if it sends the code to the same screen and you can see it.
Both devices are trusted devices. But the question is - why apple still asking verification code even for the trusted devices ? How can I stop it?

You can't stop it. That's what 2 factor authorization is supposed to do.

But no sense to show me the secret verification code on the same iMac that I am trying to login if, someone unauthorized took my iMac and somehow login by my username , the two factory authentication will protect me by sending an additional verification code. And they will send it to the same guy that is trying to log in my iMac they should avoid at least sending it to the same trusted devices from which you are trying to login.
