In Linux, there is a privilege for users like sudo privilege. In case of using the sudo command on the terminal, you will be asked for a password. When you type a password, you will not see any visual feedback like an asterisk or anything.<\/p>\n

For example:<\/p>\n

Here, we are trying to run the command \u201csudo apt update\u201d then it asks for a password. After entering the password, there is no visual feedback and it shows blank on the password section.<\/p>\n

$ sudo apt update<\/pre>\n
<\/p>\n
But if you want some visual feedback like an asterisk on the password field, it can be sorted out with small changes on the \/etc\/sudoers file. You can backup this file first before changing it with the following command:<\/p>\n
$ sudo cp \/etc\/sudoers \/etc\/sudoers.bak<\/pre>\n
<\/p>\n
To show asterisk while typing sudo password on Linux<\/h3>\n
Now, to edit the \/etc\/sudoers file, you can simply run the following command.<\/p>\n
$ sudo visudo<\/pre>\n
You must have to search the following line and do some changes on that section.<\/p>\n
Defaults env_reset<\/pre>\n
<\/p>\n
Now append pwfeedback on this line for showing the asterisk on the password section.<\/p>\n
Defaults env_reset, pwfeedback<\/pre>\n
<\/p>\n
Press ctrl + x to save the changes and then y to exit.<\/p>\n
Now you can try to run the previous command and check if you can see any visual feedback on the password section after using sudo.<\/p>\n
$ sudo apt update<\/pre>\n
<\/p>\n
Finally, you can see the asterisk as a visual on the password after some changes on the \/etc\/sudoers file.<\/p>\n
Conclusion:<\/h2>\n
Now, you get the idea to show an asterisk as visual feedback while typing sudo password. Try once on Ubuntu or Centos by doing small changes on the file on \/etc\/sudoers file. Thank you!<\/p>\n
