is it normal for my i phone 7 to requier a password change

Hi robertfromlarsen,

Here are two reasons you might be required to change your Apple ID passwords:

1. If your iPhone is provided from a school or business, there might be a mobile device management profile on the device which can require a password change. Learn more about it here Intro to mobile device management profiles. If your device belongs to a school or business, reach out to their IT team for more information.
2. If your Apple ID is disabled for security reasons, you may need to change your password to regain access. Review If your Apple ID is locked or disabled for more information.

Note: For Security and your Apple ID, change your Apple ID from Settings on your device, instead of a text, email, or pop-up.

Take care.

This is NOT normal unless the phone was given to you by your employer and the IT guys require regular password changes.

Chances are, this is likely a scam that is trying to trick you into revealing your personal details. I would delete the message or email, since Apple does not send out communications like this.
