Q: how to use itunes user id without giving payment details

Hello there Monster56,

It sounds like you want to use your Apple ID in iTunes with no payment info. This article will help you do that:

Change or remove your payment information from your iTunes Store account (Apple ID) - Apple Support

 

1. Click to open your account in iTunes. (You might need to sign in with your Apple ID.)
   
   Alternatively, you can:
   • Open iTunes.
   • Click iTunes Store.
   • Click Sign In and enter your Apple ID.
     
   • Click your Apple ID and select Account Info.

     

2. From the Account Information page, click Edit to the right of Payment Type.
   
   You can see the payment methods that the iTunes Store accepts in the Payment Type section. If you want to remove the payment method, select None in the Payment Type section. See what to do if None isn't showing or you can't select it.
3. Change your information and click Done.
   After you change your payment information, the iTunes Store places an authorization hold on your credit card.

Thank you for using Apple Support Communities.

Take care,

Sterling
