Apple ID account
I need help getting into my second Apple account that I don’t have the phone number too. Need help changing the number on the account so I can log in
To see, add, or change your trusted phone numbers:
- On your iPhone, iPad, or iPod touch: Go to Settings > your name > Password & Security. Next to Trusted Phone Number, tap Edit.
- Choose Apple menu > System Settings (or System Preferences), then click your name (or Apple ID). Click Password & Security, then add or remove a trusted phone number.
- Go to the Account Security section of appleid.apple.com.
