After resetting your login password, why is reauthentication required for iCloud on a Mac?

To synchronize preferences across devices

To enable two-factor authentication

To update the login keychain with the Apple ID password

Reauthentication is required for iCloud on a Mac after resetting your login password primarily to update the login keychain with the Apple ID password. When a user changes their login password, the associated keychain, which stores encrypted passwords and other data, does not automatically update to match the new login password. Therefore, the user must reauthenticate with their Apple ID to ensure that the keychain reflects the current credentials and can properly access all of the associated items securely.

Updating the keychain is crucial for maintaining access to iCloud services and related apps, as an invalid or outdated password in the keychain would prevent the system from connecting to these services. This process helps safeguard the user's information and ensures continued access to iCloud and other features that rely on the correct Apple ID and its credentials.
