Control what domain the browser associates with a remembered password

_x000D_ Putting the form inside an iframe will cause Firefox at least to associate any stored passwords with the domain of the iframe instead of that of the main page. You can communicate with the iframe using postMessages. Just have the iframe catch the form submit event, serialise the content of the form, and send it to the main window via postMessage; then the main window can grab the content of the form from the message and handle it using Javascript. Of course, even in simple cases this is a fairly ugly hack, and if there are complicated interactions between content in the iframe and content or code in the main page, then trying to handle them all properly via postMessage may result in a quick descent into pain and spaghetti. If the value of having cross-domain password autocompletion is low and the main issue is that having a remember password message featuring the wrong domain name is bad, then consider simply disabling the feature altogether instead of mutilating your codebase with hacks to fix it. You can disable it by setting the 'autocomplete' attribute of the form to 'off', as described here: Disable browser 'Save Password' functionality
