Summery: In this article you will learn how to display asterisks when typing sudo password in Linux terminal.

Usually, when you type a password in an application it displays a feedback using asterisks (*). But on the Linux terminal when a normal user starts typing a password to gain superuser privileges he/she won’t get any type of visual feedback on the terminal.

This is a built-in security mechanism used in Linux terminals so that no one can predict your password length. This mechanism will increase the chances that you may mess up with your password by entering it wrongly.

In this tutorial, I’ll guide you on how to display asterisks when typing your password in the Linux terminal.

  • Open your terminal and type the following.
sudo visudo

You will get an output like this.

sudo visudo
sudo visudo
