How do I disable via Javascript that cookies load data into only one specific page

I have a registration page that has email and password, when the user clicks to save email and password in the login, the auto fill of the coockies already fill in the data of the cadastre. I can not clean the coockie and they have to work normally on the other pages. (I already tried to use autocomplete="off" in html but it did not work, and I also can not make null the email and password because when the browser searches the coockies it triggers a validation).
