sysadminctl is a tool Apple introduced in 10.10 for working with system user accounts. In 10.13, sysadminctl is Apple's 
recommended tool for working with user accounts in the CLI, replacing functionality that has long been provided by dscl 
and adds new features available only in 10.13. sysadminctl can be used to change user passwords, create new users or 
check the status of a new-to-10.13 security feature named SecureToken.

the creation of a new AuthenticationAuthority entry in a user's local account record
