How do I change my Apple ID password using a different number

Hello likatu,

If we understand correctly, you are unable to log into your Apple ID because you cannot get verification codes to your new phone number.

First, we recommend trying to change your Apple ID password or get a verification code from a trusted device that is currently signed into your Apple ID: Get a verification code and sign in with two-factor authentication - Apple Support and Change your Apple ID password - Apple Support

If you don't have access to a trusted device that is currently signed in with your Apple ID, the next step is to start the account recovery process: How to use account recovery when you can’t reset your Apple ID password - Apple Support

Let us know if you have any questions! Take care.
