Where to find your network username on each device

Your network username is the name your device uses to identify itself on your WiFi network — different from your WiFi password. On Windows, Mac, iPhone, and Android, this name lives in different places, but all are reachable in under a minute without special tools.

The fastest route depends on what device you're holding right now. Windows stores it in System Settings under a tab called "About". Mac puts it in System Preferences under "Sharing". iPhones and Android phones don't display it in settings at all — you'll need to check your router's admin panel instead, which works for any device on your network.

Key Takeaways

  • On Windows 10 and 11, open Settings, go to System, then About, and look for the field labeled "Device name".
  • On Mac, open System Preferences, click Sharing, and your computer name appears at the top of the window.
  • On iPhone and Android, you cannot see the device name in phone settings — check your router's admin panel instead by typing your router's IP address into a web browser.
  • Your network username is different from your WiFi network name (SSID) and your WiFi password.
  • If you've forgotten your device name, you can change it to something you'll remember in the same settings menu where you found it.

Finding your network username on Windows

On Windows 10 and 11, the network username is called your "device name" and appears in the About section of System Settings. Click the Windows Start button, type "Settings" into the search box, and open the Settings app. Once inside, click "System" in the left sidebar, then scroll down and click "About".

Look for the field labeled "Device name" — this is your network username. It's usually something like "DESKTOP-ABC1234" or a custom name you or the previous owner set. If you want to change it to something more memorable, click "Rename this PC" on the same page, type a new name (letters and numbers only, no spaces), and restart your computer for the change to take effect.

Finding your network username on Mac

On Mac, your network username is called your "computer name" and lives in System Preferences under Sharing. Click the Apple menu in the top-left corner, select "System Preferences" (or "System Settings" on newer Macs), then click "Sharing" in the sidebar.

At the top of the Sharing window, you'll see a field labeled "Computer Name" — this is what your Mac calls itself on the network. Below it, you may also see "Local Hostname", which is a slightly different technical name but serves the same purpose. If you want to change your computer name, click the name field, type a new one, and press Enter. The change takes effect when ready without a restart.

Finding your network username on iPhone and Android

iPhones and Android phones do not display their network device names in the phone's settings app. Instead, you'll need to check your router's admin panel, which shows all devices currently connected to your network and their names. To access your router, open a web browser on any device connected to your WiFi, type your router's IP address into the address bar, and log in with your router's admin password.

Most home routers use the IP address 192.168.1.1 or 192.168.0.1 — try the first one first. You'll see a login screen asking for a username and password; these are usually printed on a sticker on the back or bottom of your router. Once logged in, look for a section called "Connected Devices", "Device List", or "DHCP Clients". Your phone will appear in that list with its device name next to it. If the name is blank or shows only a MAC address, your phone hasn't been assigned a device name on the network.

Understanding device name vs. WiFi network name

A common source of confusion: your device name (network username) is not the same as your WiFi network name. Your WiFi network name, also called the SSID, is what you see when you look for available networks on your phone — something like "Smith Family WiFi" or "Linksys". Your device name is what your individual computer or phone calls itself when it connects to that network.

Think of it this way: the WiFi network name is the name of the network itself. Your device name is the name of your specific machine on that network. You need the WiFi network name and password to connect. You need the device name if you're troubleshooting network problems, setting up file sharing between computers, or checking what devices your router recognizes.

What to do if you can't find your device name

If you've looked in the places above and still don't see a device name, it may have been left blank during setup. On Windows and Mac, you can always set one in the same location where you found it — just click the rename or edit button and type a name you'll remember. On iPhone and Android, you cannot set a device name directly in the phone; the name comes from your router's settings or is assigned automatically.

If your phone shows no name in the router's device list, you can usually assign one through the router's admin panel. Look for an option to edit or rename devices, select your phone, and type a name. Some routers also let you set a device name on the phone itself through advanced WiFi settings, though this varies by manufacturer and is not a standard feature.

Why you might need your network username

Your device name becomes important in a few real situations. If you're setting up file sharing between your computer and another device on the same network, you'll need the device name to locate the other computer. If your internet is slow or unstable, your internet service provider or router manufacturer may ask you to identify which device is causing the problem — your device name is how you tell them. If you're connecting to a network printer, the printer often needs to know the names of devices on the network to communicate with them.

Device names also matter if you're troubleshooting network conflicts — two devices with the same name on one network can cause problems, so knowing your device name helps you spot duplicates. In most home networks, you'll never need this information, but it's useful to know where to find it when you do.

Frequently Asked Questions

Is my device name the same as my computer username?

No. Your computer username is the account you log into on your device (like "John" or "Admin"). Your device name is what your computer calls itself on the network. They're separate and can be completely different.

Can I change my device name, and will it break anything?

Yes, you can change it anytime in the same settings where you found it. On Windows, restart your computer after changing it. On Mac, the change is when ready. Changing your device name will not break anything, though any file-sharing shortcuts you've set up may need to be recreated.

What if my device name has special characters or spaces?

Windows does not allow spaces or most special characters in device names — stick to letters, numbers, and hyphens. Mac is more flexible and allows spaces and most punctuation. If you see special characters in your current device name, they were set before Windows tightened its rules.

Will my device name change if I reset my device?

On Windows and Mac, a factory reset usually restores the default device name (like "DESKTOP-ABC1234"). On iPhone and Android, a reset does not affect the device name stored in your router — that name stays until you manually change it in the router's settings.

Can other people on my WiFi network see my device name?

Yes. Anyone connected to your WiFi network can see all device names in the router's admin panel if they know the router password. Your device name is not private information — it's just a label for identification on the network.
