Question: I was intrigued by this statement by [@DanWilson](http://twitter.com/DanWIlson) on Twitter:

> 
> All Web Developers: Never Ever Ever
>  put anything after the password box
>  and before submit button on a form.
>  Tab MUST go directly to submit.

When I asked for clarification, he added:

>

Can anyone point me to evidence that corroborates or contradicts that claim, even if it's anecdotal?

Answer: 
Egregious breaks in this pattern are when helpful form designers put the Forgot Password link on the tab stop after password and before the submit button. This inevitably results in the page refreshing, a new form loading. Then, when going back, as per good security practices, the password field (which I typed in the first time) is blank.

While I totally respect the aesthetic freedom of designers and developers and I do not want the web to LOOK homogeneous, the behavior of the web should be.

I don't believe the dominant UX pattern is Username TAB Password TAB Enter. Why the extra TAB+Enter after typing in the password? Save yourself a keystroke and hit Enter after entering the password to submit the form. As Chase mentions, for login forms: Username TAB Password Enter. 

I consider forms having false submit buttons by using input type='button' instead of type='submit' a more offensive UX penalty. This reinforces the TAB+Enter habit to submit a form when it should just be Enter.
