It is very useful to see *** symbols appearing I type passwords in the terminal window. Sadly, the feature is not enabled by default when using sudo in Ubuntu. Thankfully, it is simple to activate!
Just open a new terminal and run the following command,
` $ sudo visudo `
It should open a file in a text editor (Nano at the time of typing). We need to change the following line from,
` Defaults env_reset `
` Defaults env_reset,pwfeedback `
Press Ctrl + X followed by Y to save the file. Voila! We will now have asterisks when typing passwords in our terminal.
