Two-factor authentification
My phone had gotten stolen I’m trying to login to my accounts but all the codes are being sent to a phone that I don’t have
Question marked as
If you don't have another trusted device (e.g. iPad or Mac) you can get the codes sent to a trusted number which you setup.
Simply click "Didn't receive code" and you'll receive a dropdown of your pre-set alternate voice or SMS numbers which you can then select.
Also, you don't need 2FA to find your phone or activate "lost" mode.

... and if you're borrowing a friend's Apple device ... be sure to click "Use a different Apple ID" as well.
