All Engage forms are HTTPS secure, even when they are embedded in your own HTTPS-secured website via widget code. HTTPS is 128-bit encryption that is automatically applied to forms and makes a secure connection between the donor and the donation page. This ensures the authentication of the visited website and protection of the privacy and integrity of exchanged data.
You can use the following logo if you want to reassure your donors that their transactions are secure. To do so, download the image and insert it into your form as a graphic.
