We Can Help
What does my website need to be able to work with LastPass?
While LastPass can work on most website logins, if you are developing your own site you can help make it LastPass compatible by using a simple form submit with a username, password, and submit field rather.
Here's an example:
<form action="https://mypage.com/blah" method="post">
<input type="text" name="username" id="username" value=""/>
<input type="password" name="password" id="password" value=""/>
<input type="submit" value="LOGIN"/>
As far what to avoid -- always create the form on page load, even if you hide and show it on people clicking login, it's better to be there on page load. Avoid ajax for logging in. Avoid method=GET -- it's a terrible idea regardless.
