php - Html form tag autocomplete="off" attribute not working on chrome browser -

i have user registration form. form contains username , password field. @ time of user registration username , password fields automatically populated values.

i have used form "autocomplete" attribute, not working on chrome browser.

this code,

<form method="post" action=""  autocomplete="off"> <input type="text" id="first_name" name="first_name"> <input type="text" id="last_name" name="last_name"> <input type="text" id="username_name" name="username_name"> <input type="text" id="password" name="password"> 

in experience, chrome autocompletes first <input type="password"> , previous . added:

<input style="display:none"> <input type="password" style="display:none"> 

to top of <form> , case resolved.
