The Built-in password management in Web browsers
Web browsers have built-in password management designed to store
passwords used in forms on websites. Browsers often prompt to save
usernames and passwords when users attempt to logon to websites. This
facility is offered to users, so that they can logon to their frequently used
websites without having to type the usernames or passwords. However, it
is not advisable to leave the web browser store this data particularly on
public or shared computers.
