I did not knowingly autherise login for hackers.

At the time I could not login to coinbase for 2 days, and on the second day i tried to login again and again with no luck, then i get an email saying that a device wants to login, this email arrives during the exact time when i'm attempting to login, so i assumed it was sent because i was attempting to login as it stated location as uk and chrome which is what i'm using and i live in the uk. as for ip address, i don't know how to find this, but because this email arrived exactly at the time when i was attempting to login, i assumed it was because of me trying to login. Also because it mentioned that i have to access this email with the same device that i'm confirming, which i did, A hacker could not do that as he didn't have my device and my ip address would be different to the hacker. Also why did i not get F2A yet hackers still gained access.

I think this was a system glitch on coinbase and cause my account to become unsecure.

Being that i have the hackers ip address, could that be traced to the hackers location?
