Are you running any anti - virus programs? Using a VPN?

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Also try the Safe Mode.

Safe Mode - About.       

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.  Please use copy and paste as screen shots can be hard to read.

I updated about a month ago, and something similar recently started happening to me. At first, it would ask for me to verify my Apple ID for iCloud about once every few days, then daily, and now it loops as you lay out here. But it seems to be for iCloud preferences only. Facetime and Messages do not require me to log in again and are operating just fine. Screenshot of dialogue attached.

Yes this totally worked for me ! make sure you delete all files in Keychain folder though.
