Have you set up a campaign and want to show the result to your client? Do you want only a certain audience to be able to participate? Campaigns created with the Cool Promo and Cool Promo White Label applications allow you to restrict participation in a campaign by limiting access via password.
To add a password, go to the 'Basic Data' section > 'Advanced' tab, of the campaign edition.
Then, in the 'Password protected campaign' field, type the password that the participants will have to enter.
When a user clicks to participate, they are prompted to enter an access code in order to participate.
The 'Username' field can be left blank, only the password will be taken into account.
