Changing the name on the Mac lock screen is a quick way to personalize your device and enhance privacy and security. This tutorial walks you through how to change or remove your name from the Mac startup screen newer and older macOS versions.

Why You Should Change the Lock Screen Name

The name displayed on your Mac’s Lock Screen is the same as the full name of your local Mac user account. You’ll need to edit the account name to change how it appears on the Lock Screen. Here are several reasons you might want to do that:

    • Personalization: macOS allows you to easily change the full name of your Mac user account to anything you prefer. Since you’ll mostly see it on the Lock Screen, you can go with a cool nickname or preferred name.
    • Privacy: If you frequently work on your Mac in public spaces, a name change helps protect your privacy by preventing people from seeing your real name on the Lock Screen.
    • Security: If you have concerns about anyone trying to guess your login details, a generic or obscure name on the Lock Screen can be an extra layer of protection.

    Note: Changing the name of your Mac account will not affect the name of the Apple ID you’re signed in with on the device.

    Changing the Account Username, Mac Name, and Hostname

    Beyond changing your Mac account’s full name, you can modify the account’s username, the name of your Mac, and its hostname if you aim for a complete account overhaul. Before we wrap up, let’s briefly go over how that works.

    Changing the macOS Username

    Unlike your user account’s full name, modifying the account username is a complex process that can lead to data corruption if you do it incorrectly. The correct approach is to:

    1. Back up your user account data manually or with Time Machine.
    2. Create a new administrator account.
    3. Log into the new account and rename the Home folder of the other account via Finder.
    4. Modify the username for the account.
    5. Log back into the modified account.

    In macOS Monterey and older, go to System Preferences > Sharing and type the new name into the Computer Name field.

    Changing the Hostname and Bonjour Name

    Your Mac’s hostname and Bonjour name (or local hostname) are related to identifying the device on remote or local networks. You must use the Mac’s Terminal or dig into the System Settings/Preferences to modify any of them, so if you want to do that, we recommend checking our guide to changing the Mac hostname for complete instructions.
