Can't get Two-Factor code
Hello.
I'm asking this for my stepson. I have his Apple ID and password, but he no longer has the phone or phone number he used when he set up his account, so he's not able to receive a code for two-factor authentication. He purchased Final Cut Pro a couple years ago but because he can't sign into his Apple ID, he can't re-download the program to install on our new computer (he also doesn't have the laptop he owned when he first downloaded and installed it...long story).
Is there anything he can do to bypass the two-factor authentication (he's able to sign in up to the point of receiving the T-FA code)? He needs to access the App Store so he can re-download it.
Thank you.
