My sudo password was completely showing on my terminal - Ubuntu 22.04

I'm using Ubuntu 22.04 on my laptop, on my PC is normal but with my laptop, everytime I input password for sudo it was showing on screen.

I trying to edit in visudo but my password still showing on screen

Edit:

I follow your guys and typing "type -a sudo" then get this result

sudo is /usr/bin/sudo sudo is /bin/sudo

Notes: pwfeedback was not at visudo in the first time, I was read some password problems and I tried to write it into visudo. I removed it few minutes ago and it still showing sudo password.

Edit the sudoers configuration file with:

sudo visudo

and remove ,pwfeedback as this enables the password feedback i.e. indicator characters in the terminal which are usually asterisks * ... Plain text however is not enabled by that so you probably changed something else as well.

Making sudo print the plain text password in the terminal is not possible as well AFAIK.

What you might have masking your settings in the sudoers configuration file is likely an intermediate(between the user and /bin/sudo) password helper program, an executable shell script in your search path or even a shell function like this one:

sudo () 
{ 
    read -r -p "[sudo] password for ${USER}:" my_pass;
    echo "$my_pass" | /bin/sudo -S "$@"
}

You can find out which is which by running in your terminal:

type -a sudo
