You might receive an alert stating that “IP x.x.x.x is authenticating to the REST API with the admin user.”
The cause of this alert is that an external client is configured to authenticate to REST API with the admin user.
The admin user will be disabled in a forthcoming release. REST API calls from the admin user will stop working. The resolution is to authenticate to the REST API with a different user that has administrative privileges.
To resolve the warning, create another user as per the below procedure. This user can authenticate to the REST API without an alert being raised.
