How to hide User list on Ubuntu logon screen

This brief tutorial shows students and new users how to hide or disable the user list on the Ubuntu login screen.

By default, when you install Ubuntu lists all user accounts on the logon screen. All users are listed, and each user can select their account name on the list and log in by typing in the correct password.

If you want users to type their username and password – (this can add another layer of security), simply disable the user list on the logon screen.

Before a user can successfully log in, that user should be able to know both the username and the password for the account.

If you’re a student or new user looking for a Linux system, the easiest place to start is Ubuntu Linux OS. It’s a great Linux operating system for beginners and folks looking for easier Linux distribution to use.

Ubuntu is an open-source Linux operating system that runs on desktops, laptops, servers, and other devices.
