Change Your Account Name on Windows 10 and 11
The fastest way to change your name on Windows is through Settings. Open Settings by pressing the Windows key and typing "Settings," then select the app. Go to Accounts in the left menu, then click Your info at the top.
You will see your current account name displayed under "Your info." Click the blue Rename your account button. Type your new name in the box that appears—Windows allows up to 20 characters. Click Next, then Finish. Your computer will ask you to sign out and sign back in for the change to take effect. The new name will appear on your login screen and in the Start menu after you restart.
If you do not see a "Rename your account" button, your account may be a Microsoft account rather than a local account. Microsoft accounts require a different process: go to account.microsoft.com, sign in, select Your info, and change the name there. The change syncs to your computer within a few minutes.
Key Takeaways
- Windows local accounts change through Settings > Accounts > Your info > Rename your account, and take effect after you sign out and back in.
- Microsoft accounts (linked to Outlook or Hotmail) must be renamed at account.microsoft.com, not on your computer.
- Mac computers change the account name through System Settings > General > About, but the short username stays the same and does not affect file folders.
- Linux name changes depend on your distribution and desktop environment, and often require terminal commands or the Users settings panel.
- Changing your account name does not affect your files, passwords, or installed programs—only how your name appears on login and in menus.
Change Your Account Name on Mac
On Mac, open System Settings (the gear icon in the dock or Applications folder). Click General in the left sidebar, then click the About button. You will see your computer name at the top—this is what appears on your network and in Finder. Click the Edit button next to it and type your new name, then click Done.
This changes your computer's display name, but not your user account name. If you want to change the full name associated with your user account (the name that appears in login windows and system dialogs), go back to System Settings, click General, then scroll down and click Users & Groups (or Login Items depending on your macOS version). Right-click your account and select Advanced Options. You can edit the "Full Name" field here. Changes take effect when ready without restarting.
The short username—the folder name in /Users/ and the name you type at login—cannot be changed through the Settings interface. If you need to change it, you will need to create a new account with the desired username and migrate your files, or use Terminal commands. Most users do not need to change the short username.
Change Your Account Name on Linux
Linux name changes depend on which desktop environment you use. On Ubuntu with GNOME, open Settings, go to Users, unlock the panel by clicking the lock icon, select your account, and click the name field to edit it. Type your new full name and press Enter. The change takes effect when ready.
On other distributions or desktop environments, the Users panel may look different or may not exist. If you do not see a Users option in Settings, open a terminal and use the command usermod -c "New Full Name" username, replacing "New Full Name" with your desired name and "username" with your actual login username. You can find your username by typing whoami in the terminal.
Changing your full name in Linux does not affect your login username or any files. Your login username (also called the user account or home directory name) is separate and rarely needs to change. If you must change your login username, you will need to use terminal commands or create a new account, as this affects file permissions and system settings.
What Happens to Your Files and Programs
Changing your account name does not move, delete, or lock your files. All your documents, photos, downloads, and desktop items stay exactly where they are. Programs you have installed continue to work normally. Your passwords for websites, email, and apps do not change.
On Windows, your user folder (C:\Users\YourName) keeps its original name even after you rename your account. This is intentional—Windows separates the display name from the folder name to avoid breaking file paths. On Mac, your home folder (/Users/username) also keeps its original short name. On Linux, the same applies: your /home/username directory does not change when you update your full name.
If you are concerned about a specific program or file, you can test the change on a secondary account first, or straightforward proceed—account name changes are reversible. You can rename your account again at any time using the same steps.
Troubleshooting: Name Change Did Not Take Effect
On Windows, if you renamed your account but the new name does not appear, sign out completely and sign back in. Press Ctrl+Alt+Delete, select Sign out, wait 10 seconds, then log back in. If the old name still appears, restart your computer—some system processes cache the old name until a full restart.
If you see an error message saying "You do not have permission to rename this account," your account may not have administrator rights. Ask the person who set up your computer to give your account administrator status, or create a new administrator account and rename that one instead.
On Mac, if the name change does not appear in login windows, restart your computer. If it still does not show, check whether you changed the computer name or the account full name—they are different settings, and you may need to change both.
On Linux, if the terminal command returns "Permission denied," you may need to use sudo before the command. Type sudo usermod -c "New Full Name" username and enter your password when prompted.
When to Change Your Account Name
You might change your account name after a legal name change, to match a preferred name, or straightforward because you want a different display name. The process is straightforward and safe on all three operating systems.
If you share a computer with other people, changing your account name makes it clearer whose account is whose on the login screen. If you are setting up a new computer and the default name is generic (like "User" or "Administrator"), renaming it when ready makes the system feel more personal and organized.
Some people change their account name to match their workplace or school username for consistency, especially if they use multiple computers. Others change it to remove a name they no longer use. Whatever your reason, the change is quick and does not affect anything else on your computer.
Frequently Asked Questions
Will changing my account name log me out of websites or apps?
No. Your account name on your computer is separate from your usernames and passwords for websites, email, and apps. You will stay logged in to everything. The only thing that changes is how your name appears on your computer's login screen and in system menus.
Can I change my account name if I forgot my password?
On Windows and Mac, you need to be signed in to change your account name. If you forgot your password, you will need to reset it first through your Microsoft account (Windows) or Apple ID (Mac). On Linux, you can change the full name from the login screen if you have sudo access, but you still need to know your password.
Does changing my account name affect my email or Microsoft/Apple account?
No. Your computer account name is separate from your email address and online accounts. Changing your computer name does not change your email, and your email does not change your computer name. If you want to change your Microsoft or Apple account name, you do that on their websites, not on your computer.
What if I change my account name and then want to change it back?
You can rename your account as many times as you want using the same steps. There is no limit to how many times you can change it, and no penalty for doing so. straightforward follow the same process and enter your new name.
Can I have two different names on the same computer?
Yes. Each user account on your computer can have its own name. If you have multiple accounts (one for work, one for personal use, for example), each one can have a different display name. Create a new account through Settings and give it the name you want.
