What Should I Do If I Forgot My ITunes Account Password?
Forgot pass word for itunes
There is a place on the itunes website where you can let them know that you have forgotten your password. They will email it to you.
I tried so many things to find out how to get my pass word I just don't know what to do... Any ideas?
