Make your login screen a username-free zone
By default, the macOS login screen displays the username and user icon for every account on your Mac. However, if you’re craving a more simplified look, then you can remove all of the usernames and icons from your login screen. With this information banished from your login screen, macOS will display two blank text boxes where you can enter the username and password for the account that you want to access. Removing the username and user icon can also give your Mac an extra layer of security, since anyone who’s attempting to break into your account will need to know your username rather than having this information handed to them as soon as they power up your Mac. To remove all the usernames and icons from your login screen: That’s it! The next time you want to log in to any account, you’ll need to enter that account’s password and username.

Do you want to pick and choose which accounts appear on the login screen? Perhaps you want to hide all of your guest accounts and place your personal account center stage? Or maybe you want to add some extra security to your admin account, by making sure it doesn’t appear on the login page? You can bundle multiple macOS accounts into an “Other … ” overflow category. If you want to access one of these hidden accounts, you’ll need to select “Other … ” and then enter the password and username for the account you’re trying to access. To hide a specific user account from the login screen: All of these accounts will no longer appear on your login screen, and you’ll only be able to access them by selecting “Other … ” and then typing the username and password associated with that account.
Help! I’ve forgotten my username
When an account is hidden, you’ll need to know that account’s exact username in order to access it, but what happens if you forget or misplace a username? If you still have access to at least one other account, then you can log into that account and retrieve a list of all the usernames that are registered with your Mac. To retrieve this information, open the Terminal application and run the following command: The Terminal will now display a list of all the accounts that are registered with your Mac. Alternatively, if you can’t access any of your accounts, then you can retrieve a list of usernames by booting into macOS’s Single User Mode: Your Mac will now restart, and after a few moments you should see the standard macOS login screen.
