I forgot my ITunes password

So what password might you be talking about?

About the only other password I can think of that’s iTunes related is for an encrypted iOS backup.

Without that password, you can never retrieve the backup.

Asked and answered. Of course, I had to assume what “iTunes password” means as there really is no such thing.
