You can enable the password feedback feature in /etc/sudoers file, but first create a backup of the file, then open it for editing using the visudo command.

$ sudo cp /etc/sudoers /etc/sudoers.bak
$ sudo visudo 

Search for the following line.

Defaults env_reset

And append pwfeedback to it, so that it looks like this.

Defaults env_reset,pwfeedback

Now press Esc key and type :wq to save and close the file. But if you are using nano editor, save the file by hitting “Ctrl+x” and then “y” followed by “ENTER” to close it.

Then run the command below to reset your terminal for the above changes to start working.

$ reset

That’s it
