First Backend Administrator
On a new installation with an empty database, running this command from a terminal prompts for the username, email address, and password of the first backend administrator. The password must be at least 4 characters and is entered twice. When the command can’t prompt (for example, when it runs from a script or with--no-interaction), the first
administrator is created with the username admin and a password that isn’t shown. Set its password afterwards with
php artisan winter:passwd admin.
