Password Protect Forms – this requires users to enter a password to submit the form. This added protection helps decrease the number of unwanted forms of submission.
Close Form Submissions After Specific Date / Time – this is great for any kind of application form or other time-sensitive forms.
Limit the number of total submissions – this is great for contests or giveaways. Once the max number of entries are in, the WPForms will automatically close the form.
Limit one entry per person – if you want to avoid duplicate submissions, then you will love this option. This is very useful for scholarship applications, giveaways, etc.
Restrict Forms to Members Only – you can restrict your forms to logged-in users of your WordPress site. This is great for membership sites or businesses that want to restrict support to paid customers only.
