A temporary account is a type of user account, used by unregistered editors. A temporary—mostly numeric—username is assigned to the user and lasts for about 90 days before being replaced with another if the user remains active. Like with registered accounts IP address information is collected. While not displayed publicly, it is available to administrators and other users with the proper permissions.
