I wanted to play Minecraft again for a long time. I bought the game on my old Apple ID. Unfortunately, two-factor authentication is on, which means that I can't access my old Apple ID. The number is my old number. A message was sent to iForgot. But I have access to the e-mail or Gmail from this ID.
If two-factor authentication is activated, you can only use it with the appropriate second factor.
Some services also offer backup codes as an alternative if access to the second factor is no longer available.
I would say: lost account. But I'm also not an Apple expert…
It has already been clarified, my old iPad, which is with my grandma, has my Apple ID
