Flushing local keychain daemon caches and re-authenticating with primary device lock screen passcode.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Confirm saved passwords exist locally on your iPhone in Settings > Passwords.
  2. On Mac, turn Passwords & Keychain OFF in iCloud settings.
  3. Purge local keychain cache: rm -rf ~/Library/Keychains/*/ && sudo killall -9 securityd secd.
  4. Re-enable Keychain in iCloud settings and verify identity with iPhone lock screen passcode.

Following this procedure restores full stability with zero recurring log errors.
