autocomplete=”off”

Something I haven’t thought about much, but very important: for sensitive information, turn off autocomplete on input tags.
<input type="text" name="super-secret-pin-num" autocomplete="off" />
It’s a non-standard attribute, but all the major browsers implement it (including Webkit/Safari).
