Welcome to justanswer.com, my name is ***** ***** I will do my best to assist you.
Before you do the following, which will accomplish exactly what you want. Make sure that you have a backup email and a recovery phone number listed for your apple id.
Once you have verified that, then all you need to do is create an app specific password ***** itunes, or itunes match, that way that y our not using your actual icloud / apple id password, but a generated password ***** only for the itunes or itunes match.
You may want to change your icloud / apple id password ***** that way that no one else knows it.. A nd then when you create the app specific password, that singular password ***** that app itself, is the only one anyone else would have or need.
If you get stuck or have further questions, let me know.
