Your username is the name your computer uses to identify you, and you can find it in seconds from your system settings

Your computer username is the account name your operating system assigns to you. It appears when you log in, shows up in file paths, and identifies you on a network. You may need it to troubleshoot problems, set up shared folders, or understand file permissions. The steps to find it differ slightly depending on whether you use Windows, Mac, or Linux.

Key Takeaways

  • On Windows, open Settings, go to Accounts, and your username appears under "Your info" at the top of the page.
  • On Mac, open System Settings, click General, then About, and your computer name is listed as "Computer Name" — your user account name is in the top-left corner of the menu bar.
  • On Linux, open a terminal and type whoami to see your username when ready.
  • Your username is different from your display name or full name — it is the short identifier your system uses behind the scenes.
  • If you see an Administrator account and a Standard account, you may have more than one username on the same computer.

Finding your username on Windows 10 or 11

Open the Settings app by pressing the Windows key and typing "Settings," then press Enter. Click on Accounts in the left sidebar. At the top of the page under "Your info," you will see your username displayed next to a profile picture. This is the name Windows uses to identify your account.

If you want to see it another way, you can also right-click on "This PC" or "My Computer" on your desktop, select Properties, and look for "Full computer name" — though this shows the device name, not your user account name. The Settings method is faster and clearer.

Finding your username on Mac

Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older versions). Click General in the sidebar, then click About. You will see "Computer Name" listed here, but this is your device name, not your user account name.

To find your actual user account name, look at the top-left corner of the menu bar — it often shows your account name next to the Apple logo. Alternatively, open Finder, click Go in the menu bar, select Home, and look at the folder name in the window title or address bar. That folder name is your username. You can also open Terminal (in Applications > Utilities) and type whoami, then press Enter to see your username when ready.

Finding your username on Linux

Open a terminal window — the method varies by desktop environment, but you can usually right-click on the desktop and select "Open Terminal" or press Ctrl+Alt+T. Type whoami and press Enter. Your username will appear on the next line.

If you want more detail, type id and press Enter to see your username, user ID number, group ID, and group memberships all at once. Both commands work on any Linux distribution.

Understanding the difference between username and display name

Your username is what the system uses internally — it is usually short, contains no spaces, and appears in file paths and terminal commands. Your display name or full name is what shows up in menus and on login screens, and it can contain spaces and special characters.

For example, your username might be "jsmith" but your display name might be "Jane Smith." When you share files or folders on a network, other people see your username, not your display name. If you are troubleshooting a problem and someone asks for your username, give them the short system name, not the full name.

What to do if you have multiple user accounts

If your computer has more than one user account — such as an Administrator account and a Standard account — each one has its own username. When you follow the steps above, you will see only the username for the account you are currently logged into.

To see all usernames on your computer, you can check Settings on Windows (Accounts > Other people shows other accounts on the device) or System Settings on Mac (Users & Groups shows all accounts, though you may need to unlock the settings first). On Linux, type cat /etc/passwd in a terminal to see all user accounts on the system.

Why you might need your username

Your username appears in several places. It shows in file paths when you save documents to your user folder. It appears in network settings when you share files or printers. Technical support may ask for it when troubleshooting. Some programs store settings in folders named after your username. Understanding where to find it saves time when you need it.

Frequently Asked Questions

Is my username the same as my email address?

No. Your username is a local account name on your computer. Your email address is separate. Some services (like Microsoft or Apple accounts) use your email to log in, but your computer username remains different. Check your Settings or System Settings to see your actual username.

Can I change my username?

Yes, but the process is different on each system. On Windows, you can change your display name easily in Settings, though changing the actual account name is more involved. On Mac, you can change your display name in System Settings, but changing the account folder name requires more steps. On Linux, you can use the usermod command. If you are unsure, look up the specific steps for your operating system version.

What if I forgot my password but remember my username?

Knowing your username does not let you bypass a forgotten password. You will need to use your operating system's password recovery method — usually a recovery email, security questions, or a recovery code. Start by clicking "I forgot my password" on your login screen and follow the prompts.

Does my username appear when I browse the internet?

No. Websites do not see your computer username. They see only what you tell them — your email address, display name, or username you create on their site. Your local computer username stays on your device and is not sent to websites.
