itunes passwords reset

Welcome to the Apple Support Communities!

If you are having trouble with the Apple ID password that you use for the iTunes Store, take a look at the resources below. Once you change a password, there are several services and settings on your iMac and iPhone that need to be updated as well. You might also consider setting up two-factor authentication for your Apple ID. I'll include some resources below to provide more information about your security options and to get additional help if needed.

Hopefully you've been able to identify, and test a solution. I've had the similar concern, and finally I can say to the family it wasn't me playing tricks on them.

My suggestion is to verify the password in the Keychain. When I verified the password in Keychain, it was completely not something I would have chosen. Frankly, it was most likely a result of iOS choosing on my behalf. Odd for sure, as I don't utilize that function. Give it a try, and keep me posted.
