eSign iFrame on a mobile device

The esignlive signing ceremony page isn't responsive in itself but you can definitely make the height and width of the iframe to be responsive. Here's one example: https://community.onespan.com/forum/setting-e-signlive-iframes-height-same-height-browsers-viewport As for loading the iframe directly to the signature, I'm not entirely sure you can do this. If it's possible, you would have to use some JavaScript/CSS and then again, you might run into CORS (cross-origin resource sharing) issues. There is no call available in eSignLive that loads the page directly to signature because the signer has to read everything before the signature, for legal purposes.
