Why is it necessary to verify my identity when I change the security phone number or email address?

Because the security phone number or email address can be used to reset the password. They play an important role in protecting your account. Therefore, when you are changing the security phone number or email address, a verification message or email is sent to confirm that the change is performed by yourself.
