How does simple analytics know I'm the owner of the website?

I just installed SA on all my websites with the student subscription and I think it’s great! But I don’t get how does it verify I’m the owner. I’m wondering because I don’t have to put a code in my website code like for GA4.

Thanks!

I’m not clear, but to guess I think the first account to ‘claim’ a website after the simple analytics code is installed becomes the owner.
