how do i autherize my phone

Hello maxx272,

Thanks for asking the Apple Support Communities about authorizing your phone. I believe you are asking about your device asking about a verification code for two-factor authorization.

This article has information and options to get another code sent, and talks about trusted devices as well as keeping your trusted numbers updated: Two-factor authentication for Apple ID - Apple Support

There is also information about about recovering your account if you have no other option available from the article. Thanks and have a wonderful day.
