Couldn’t sign into my Apple ID when I got a new phone because my trusted phone number is from a few years ago and I don’t remember it I can’t back up my contacts and pictures
Refer to this link for support on two-factor authentication: Two-factor authentication for Apple ID - Apple Support
See if anything here helps. If necessary, you can use account recovery as explained in the link at bottom of the article.
Verification code - how to get one and sign in with two-factor authentication.
If you can get a verification code, you need to change/add the number on your Apple ID. After the change, allow up to 24 hours for the change to sync. Before trying to make the change, sign out of Messages/FaceTime on all devices/computers.
