Passwords in IE, Firefox, Safari etc. being stored on laptops.

Passwords in IE, Firefox, Safari etc. being stored on laptops.

I have just added my first "secret". While testing the security features i noticed that the "click to login" is just pasting the info into the fields. Problem is that i can easily go to the password manager in my browser and retrieve the passwords (after you save in keychain etc). 

Is there a setting that will not allow for this info to be saved on my techs computer?
