Abstract: A method for sending secure content to a content recipient via a mobile device comprises receiving, by a third-party proxy service, a content delivery message containing a URL to a web resource containing the secure content. Responsive to receiving the message, the third-party proxy service: sends a message to the mobile device containing a proxied URL selectable for routing the mobile device to the secure content page, via the third-party proxy service; receives a content request from the mobile device for accessing the proxied URL; communicates with the mobile device to authenticate the user, based on biometric data provided by the user; and responsive to determining that the user is the content recipient based on a positive authentication, proxying the content request to the web resource containing the secure content.
