Resetting the Cookie with a new value?

[Anon]

Hi,
Could anybody help me to solve this.

When the user logged in to the form i set the cookie like (setcookie ("Cookie", "user and password ", time() + 3600)) I need to update the cookie with newer password value when the user update his password. I could not set the newer value and it is not accepting. could anybody tell how to set the cookie with the newer value?

Thanks in advance
