//Normal Password Login Form
<div style="margin: 200px auto;width:400px;text-align:center;">
    <h3>{text key='base+password_protection_cap_label'}</h3>
    <div style="padding: 5px 0;">{text key='base+password_protection_text'}</div>
    {form name='password_protection'}
    <div style="padding: 5px 0;">{input name='password' style='width:200px;'}&nbsp;{submit name='submit'}</div>
