settings[ Random]
This shortcode will generate a random numeric number.
Can be used as a unique identifier to identify users in a multistep form if you don’t require their email address as a first step for example. Simply add this shortcode as “prefill” to a hidden field, and use a [ SyncFields] shortcode to propagate that randomly generated identifier across your different forms.
Note : This will require you to add the fields to your page and hide them via clickfix Hide shortcodes
