Similar to the trustd process, coreauthd is a daemon responsible for managing local authentication on macOS. Daemons, identifiable by the 'd' at the end of their names, operate in the background and handle various system tasks. Coreauthd specifically handles tasks related to local authentication, such as password entry and Touch ID usage.

coreauthd, a system daemon, offers LocalAuthentication services. It manages authenticated contexts and facilitates the authentication user interface.
Essentially, coreauthd prompts password requests when users attempt changes permissible only under Admin privileges. For MacBook owners with Touch ID, coreauthd handles these prompts as well.
coreauthd also regulates the duration of your upgrade permissions in action. For instance, input your password in System Preferences to make Admin-level changes, and you retain Admin access to system settings until you close the System Preferences window.
Closing the System Preferences window necessitates re-entering your password to enact Admin-level changes, managed by coreauthd.
Coreauthd isn't a complex process, but it's vital for Mac operation. If coreauthd consumes excessive memory or CPU resources, or if it hangs, you can terminate the process using the Task Manager on Mac, known as Activity Monitor. Mac will promptly restart to address the issue.
This Mytour article clarifies what coreauthd is and why it runs on Mac. If you notice the process consuming high CPU, terminate it via the Activity Monitor window to resolve the issue.
