Q: Expired Password Woes

Hi,

I feel a need to point out that your expired password flow is rather broken.  Every now and then Apple will force me to reset my Apple password due to the old password expiring. 

When this happens, I'm prompted to reset my password on every single Apple product that I own.  My Mac, iPhone, and iPad all ask me to change my password.  When I change my password through the prompted flow on one of these devices, one of two things seem to happen:

1. The other devices seem to be unaware that I changed my password.  I.e., if I update my password on my Mac, then when I access my iPhone it prompts me to enter in my new password - after doing so it sends me through the change password flow even though I just changed it.  Thus I end up having to change my password twice for no-apparent reason.
2. The device flat out fails to sign-in with the password I just created.  I get a generic error stating "there was a problem" and the device refuses to sign-in.  This issue will persist until I physically reboot the device in order for it to take the new password, otherwise it never will and I'm locked out of all of my Apple services (iCloud, iTunes, etc.)

Another thing to note is that when a user's password is expired, the user is silently logged out of iMessage on all of their devices.  I think this is critical, for the user has no idea they've been logged out until they try to send messages - note that they're all failing, and debug the issue to discover they've been logged out.

This stuff is probably worth fixing.
