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

Your computer username is the account name your operating system uses to log you in and organize your files. It appears in your file paths, email settings, and network connections. You do not need to dig through system files or call support — it is visible in your settings right now, and the steps differ slightly depending on whether you use Windows, Mac, or Linux.

The method you use depends on your operating system, but all three take less than a minute. If you share a computer with other people, your username is only the account you personally use to log in, not the names of other accounts on the machine.

Key Takeaways

  • On Windows 10 or 11, open Settings, go to Accounts, and your username appears at the top of the page under "Your info".
  • On Mac, click the Apple menu, select System Settings, go to General, then Users & Groups, and your account name is listed on the left side.
  • On Linux, open a terminal and type whoami to see your username when ready, or check the top-right corner of your screen if you use a graphical desktop.
  • Your username is different from your password and different from your email address, though they may look similar.
  • If you cannot remember your password but know your username, you can use that username to reset your password through your account recovery options.

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. Your username appears at the top of the page under the heading "Your info," displayed next to a profile picture or avatar.

If you see a Microsoft account email address instead of a straightforward username, that is your account name for Windows. Some computers also show a "local account" name if the computer was set up without a Microsoft account — in that case, the local account name is your username.

You can also find your username by right-clicking on "This PC" or "My Computer" on your desktop, selecting Properties, and looking for "Computer name" under the Device name section. That is your computer's network name, which is often the same as your username but not always.

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 select Users & Groups (or Accounts on older versions). Your account name appears in the list on the left side. If you see a lock icon, click it and enter your password to view the full details, but you do not need to make any changes to see your username.

A faster way: open Finder, click Go in the menu bar, and select Home. The folder name that opens is your username — it usually appears in the window title or the sidebar. This method works on any Mac and requires no password entry.

Finding your username on Linux

Open a terminal window. Type whoami and press Enter. Your username appears on the next line. This works on any Linux distribution and is the fastest method available on any system.

If you use a graphical desktop environment like GNOME or KDE, click the system menu in the top-right or top-left corner of your screen, depending on your desktop setup. Your username usually appears there, sometimes next to a profile icon. You can also open your file manager and look at the sidebar — your home folder is often labeled with your username.

What to do if you see multiple usernames

Some computers have more than one user account. If you see a list of usernames and are not sure which one is yours, log out and look at the login screen — the account you use to log in is your username. On Windows, you can also open Settings and check which account is marked as "Administrator" or "Standard user" — the one you are currently using is your account.

If you share a computer with other people, each person has their own username and their own set of files and settings. Your username is only the one you use to log in, not the names of other accounts on the machine. You can see all accounts on the computer, but only your own account name matters for your purposes.

Why you might need your username

Your username appears in many places: when you set up email clients like Outlook or Gmail, when you connect to a work network or VPN, when you troubleshoot printer or file-sharing problems, and when you contact technical support. Having it written down saves time and prevents confusion with your password or your email address.

Some software also asks for your username during installation or setup. Knowing it ahead of time means you can fill in the field correctly without guessing or restarting the process. Network administrators and IT support staff often need your username to troubleshoot issues or grant you access to shared resources.

Frequently Asked Questions

Is my username the same as my password?

No. Your username is the name your computer uses to identify you. Your password is the secret code you type to prove you are that person. You need both to log in, but they are separate things. Never share your password, but your username is not secret.

Is my username the same as my email address?

Not always. Your email address is something you use to send and receive mail. Your computer username is what your operating system calls you. They may look similar or even be identical, but they serve different purposes. Your email address is not required to be your username.

What if I forgot my username and cannot log in?

If you cannot log in, you can usually see a list of usernames on the login screen itself. Click on each one to see if you recognize it. If you remember your password but not your username, try typing your email address or full name instead — many systems accept either one at the login prompt.

Can I change my username?

Yes, but the process varies by operating system and can affect file paths and network connections. On Windows, go to Settings > Accounts > Your info and click "Rename your account." On Mac, go to System Settings > General > Users & Groups, unlock the settings, right-click your account, and select "Advanced Options." On Linux, use the terminal command usermod, though this requires administrator access.

Do I need my username to reset my password?

Usually yes. When you reset a forgotten password, the system asks you to enter your username first, then sends a recovery link to your email or phone. Knowing your username makes password recovery faster and more reliable.
