Are the Two Authentication codes specific to each mac?

I carefully copied down the verification code but it didn't work when I was on another mac. So I am wondering if you have to have a code for each mac rather than one code, like a password is, for all your macs.

If you are referring to the 2factor authorization, a unique code would be issued per event, not per machine...
I think it lasts around ten minutes.

Those codes are not permanent - they expire. Please give some thought to turning off TFA until you can find someone to sit down with you to explain what TFA is and how it works.

That's not a bad idea. If it throws you and you've followed Apple's prompts to use the Apple ID password everywhere, that can easily lead to a lock-out.

To remove two-factor authentication reliably, sign into appleid.apple.com as per these instructions:
