Hey there Gobbler67,
Thanks for reaching out to the Apple Support Communities.
Just to confirm, are you receiving these requests in an email, or are you seeing a pop-up appear on your iPhone display? If you're receiving these requests in an email, we would recommend reviewing the following resource just to ensure that the emails may not be phishing attempts attempting to gain access to your account and information: Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support
If you're seeing a pop-up notification on your iPhone display, or you've confirmed that the email you've received is legitimate, we would recommend through the steps in the next resource to ensure that your account is secure: If you think your Apple ID has been compromised - Apple Support
If you have any other questions or concerns about these alerts, the best option would be to reach out to Apple Support directly. You can do reach out to Apple using this link here: Contact - Official Apple Support
We hope that's able to help.
Have a great day!
