Ubuntu 20.04 Login with no "see password" option

Question

is there a way to disable the eye icon in the login screen to prevent from someone "accidentally" turning it on and thus showing their password in plain sight? Thank you!

Answer 1

Assuming you have a fresh install of Ubuntu 20.04, The workaround is to set the eye-icon size to 1px so that it is not visible and not reactive..

To use the workaround

Download the script from github with below command..

wget -qO - https://github.com/PRATAP-KUMAR/focalgdm3/archive/remove-eye-icon.tar.gz | tar zx --strip-components=1 focalgdm3-remove-eye-icon/focalgdm3

Run the command

sudo ./focalgdm3 \#4f194c

Optionally you may change the color #4f194c in above command with any color or you may replace the color \#4f194c with an absolute path of the Image if you wish an Image as background.

For reverting back to normal

Run the command

sudo ./focalgdm3 --reset

The above works only for login screen.. and not for lock screen, to use the same theme file for lock screen, we need to configure it separately.

---

Configuring the same file for lockscreen

copy the gresource file used for login screen with below command to system default folder

sudo cp /usr/local/share/gnome-shell/theme/custom/custom-gnome-shell-theme.gresource /usr/share/gnome-shell/theme/Yaru/

$ ls /usr/share/gnome-shell/theme/Yaru/
custom-gnome-shell-theme.gresource  gnome-shell-theme.gresource
$ 

Now to get away the changes we are doing from system upgrades.. make a local copy of the file /usr/share/gnome-shell/modes/ubuntu.json

sudo mkdir -p /usr/local/share/gnome-shell/modes
cp /usr/share/gnome-shell/modes/ubuntu.json /usr/local/share/gnome-shell/modes

Open the file ubuntu.json

sudo -H gedit /usr/local/share/gnome-shell/modes/ubuntu.json

Now edit the ubuntu.json file to use our login screen gdm3.css file with below content..

{
    "parentMode": "user",
    "stylesheetName": "gdm3.css",
    "themeResourceName": "theme/Yaru/custom-gnome-shell-theme.gresource",
    "debugFlags": ["backtrace-crashes-all"],
    "enabledExtensions": ["ubuntu-dock@ubuntu.com", "ubuntu-appindicators@ubuntu.com", "desktop-icons@csoriano"]
}

Now reboot to see the changes..

To revert back to normal, remove the two files we created for lock screen purpose..

sudo rm /usr/local/share/gnome-shell/modes/ubuntu.json /usr/share/gnome-shell/theme/Yaru/custom-gnome-shell-theme.gresource
