Whenever you are prompted to enter a password in the Debian terminal, enter your password without receiving any visual indication or feedback from the screen. In such a situation, there is a possibility that you could falsify your password by entering it incorrectly. This is the reason why visual feedback is so important. It helps you keep track of the number of characters you enter, especially while you are typing passwords, so you can’t miss any characters or enter additional characters. Such visual feedback is provided by the display of asterisks (***) when entering passwords. In this article, we will tell you how to enable this feature in the Debian Buster 10 terminal.
Important: Here it is important to mention that while it is useful, it is not a very good security practice to make the asterisks visible. It gives away the number of characters in your password if your computer is shared or remotely accessible. So the as-te risks actually make your PC risky.
