Hello, ricandhaz!

Thanks for reaching out to the Apple Support Communities! It sounds like you're getting repeated requests to log into your Apple ID. To aid us in investigating this issue, take a look at the "If you are repeatedly prompted to enter your Apple ID password on your Mac or iOS device" section of the following article of this article If you can't connect or sign in to iCloud.

"If you are repeatedly prompted to enter your Apple ID password on your Mac or iOS device

• If you have recently restored your iPhone, iPad or iPod touch from an iCloud backup, the restore may not have completed. Stay connected to a reliable Wi-Fi network and power source until the restore finishes. Follow these steps if iCloud Backup couldn't be completed or you can't restore. 
• If you recently changed your Apple ID password, you might need to update your sign-in information with iCloud services you use. Make sure that each service is using your updated sign-in information on your device.
• Check if you have Automatic Downloads enabled. If there is content ready to be downloaded, you may be prompted to enter your Apple ID and password to continue. Learn how to resume interrupted downloads. 
• If you are an organizer, parent, or guardian of a Family Sharing group, check if the prompt is a request from a child family member to make an iTunes Store purchase. You can then approve or decline the request. "

If after following through the steps in the article you're still being asked for your log in repeatedfly, we would recommend reaching out to Apple directly by checking out this link to Get Support and they will be more than happy to proceed with additional steps.
