Most applications normally display a feedback using\u00a0asterisks<\/strong>\u00a0(*******<\/code>) when a user is typing a password, but on the Linux terminal, when a normal user runs the\u00a0sudo command<\/a>\u00a0to gain super user privileges, he\/she is asked for a password, but no visual feedback is seen by the user while typing the password.<\/p>\n

In this article, we will show how to display asterisks as feedback when you type passwords in the terminal in Linux.<\/p>\n

Take a look at the following screen shot, here the user\u00a0tecmint<\/strong>\u00a0has invoked the\u00a0sudo command<\/strong>\u00a0to install the\u00a0vim text editor<\/a>\u00a0in\u00a0CentOS 7<\/strong>, but there is no visual feedback as the password is typed (in this case the password has already been entered):<\/p>\n

$ sudo yum install vim\r\n<\/pre>\n
\n
\"No<\/a><\/p>\n
No Sudo Password Shown<\/p>\n<\/div>\n
You can enable the password feedback feature in\u00a0\/etc\/sudoers<\/strong>\u00a0file, but first create a backup of the file, then open it for editing using the\u00a0visudo<\/strong>\u00a0command.<\/p>\n
$ sudo cp \/etc\/sudoers \/etc\/sudoers.bak\r\n$ sudo visudo \r\n<\/pre>\n
Search for the following line.<\/p>\n
Defaults env_reset\r\n<\/pre>\n
And append\u00a0pwfeedback<\/strong>\u00a0to it, so that it looks like this.<\/p>\n
Defaults env_reset,pwfeedback\r\n<\/pre>\n
\n
\"Configure<\/a><\/p>\n
Configure Sudoers File<\/p>\n<\/div>\n
Now press\u00a0Esc<\/strong>\u00a0key and type\u00a0:wq<\/code>\u00a0to save and close the file. But if you are using nano editor, save the file by hitting \u201cCtrl+x<\/strong>\u201d and then\u00a0\u201cy\u201d<\/code>\u00a0followed by\u00a0\u201cENTER\u201d<\/strong>\u00a0to close it.<\/p>\n
Then run the command below to reset your terminal for the above changes to start working.<\/p>\n
$ reset\r\n<\/pre>\n
That\u2019s it, now you should be able to see a visual feedback (****<\/code>) every time when you typing a password on the terminal, as shown in the following screen shot.<\/p>\n
$ sudo yum update\r\n<\/pre>\n
\n
