Perhaps you share your Mac with other people and don’t like the thought of them potentially having access to your accounts maybe you prefer to store all your passwords in a dedicated password manager app or maybe you have a great memory and like the added security of knowing your passwords aren’t stored anywhere except in your own head. While this feature can make your life easier, sometimes you might not want your web browser to remember your passwords.
Whenever you enter a password anywhere online, most modern web browsers will ask whether you want it to remember this password.
