I am trying to implement remember me functionality using JSF 2.0 and not sure how to implement COOKIES to do that. Can you share a working sample code?
Edit: Do not store password nor username in cookies !
See this post by BalusC for a better implementation.
I believe this might help you:

NOTE In order to save password browser will prompt to save password or not irrespective of Java Web Technologies and browsers setting and retrieving cookies will play a major role.
