If you have used the terminal in Linux (or Mac), you will know that it does not show anything when you type a password. The lack of a feedback system means that you won’t know if you have typed a password, or have entered the correct number of characters. Here is how you can make the terminal show asterisks when you type a password.

1. Open a terminal and type: 

sudo visudo

2. Scroll down the list until you find the line:

Defaults        env_reset

3. Append the word “pwfeedback” to the end of the line so it looks like:

Defaults        env_reset,pwfeedback

add-password-asterisk-to-terminal

Save (ctrl +o) and exit (ctrl +x).

That’s it.
