Logging in on a new Device

Hey, I’ve been searching google for about an hour not still not finding an answer to my question…

I do not have the mobile app authenticator activated and I wanna log into a new device and play cod when I got on my trip but the issue is, I have an old phone number I no longer have accesses to on my account, i’m waiting on a reply for my ticket but if I want to log in on a new device can I use my email for a code verification or will I NEED my phone number?
