Where is the Wi-Fi password written on the router: searching on the case and in the system

Many users are familiar with the situation of needing to connect a new device to a wireless network but losing or forgetting the access key. The first and most obvious place to look is the router itself. Manufacturers of home and office equipment are required to provide basic setup information so that customers can start using the device immediately after purchase.

Typically, all the necessary information is contained on a special factory label attached to the bottom of the case or, less commonly, to the rear panel near the ports. This label indicates the factory settings, which are valid unless you or the previous owner manually changed them through the web interface. Default password - this is exactly the meaning that needs to be looked for first.

However, visual search can be complicated by the fact that the stickers use various symbols, abbreviations, and codes that are incomprehensible to the average user. Furthermore, over time, the label may fade, wear off, or be covered with a seal. In this article, we'll detail where to look for the coveted numbers and letters, how to read them correctly, and what to do if the standard method doesn't work.

Find the factory sticker on the device body

The vast majority of modern routers, whether models from TP-Link, Asus, Keenetic or MikroTik, have an information sticker. It's most often located on the bottom of the device, which is on the bottom when the router is in a vertical position. If your router is wall-mounted, the sticker may be on the back. Factory label — This is the main source of truth about default settings.

This sticker typically contains the manufacturer's logo, device model, serial number (S/N), MAC address, and connection information. You're interested in the field, which may have a different name: Wireless Password, WPA/WPA2 Key, PIN or simply PassIt is important to understand that this is the initial password set at the factory.

⚠️ Note: If the router has been used previously and the security settings have been changed, the password on the sticker will likely no longer work. In this case, it will only be valid after a full factory reset (hard reset).

Sometimes manufacturers hide some of the information under a protective layer that needs to be scratched off with a coin, like lottery tickets, although this practice has been moving away from recently. Also, on some models, for example, Xiaomi or HuaweiA QR code may be printed along with the password. Scanning it with your smartphone's camera allows you to automatically connect to the network without manually entering characters.

Decoding the symbols and fields on the label

Once you've found the sticker, you'll be presented with a set of technical data. Not all of this is the Wi-Fi password, and it's important not to confuse them. Users often enter the WPS PIN or MAC address instead of the security key, which results in connection errors. Let's take a look at the main fields you might encounter.

The most important field is Wireless Key or WPA-PSKThis combination of letters and numbers is required for authentication on a wireless network. It can be 8 or more characters long. The network name (SSID) is often listed next to it, and can also be found in the list of available connections on your phone or laptop.

Also on the label there is often a field WPS PIN or simply PIN CodeThis is a code for quickly connecting devices without entering a long password, but it doesn't always match the Wi-Fi password. Entering it in the password prompt during a normal connection is pointless unless the router specifically requests a WPS code.

The difference between a PIN and a Password

The PIN code is used by the WPS protocol to automatically transmit the password to the device. The password (key) is the network encryption key itself. In 90% of cases, they are different, but on very old D-Link and TP-Link models, they were sometimes the same.

For clarity, let's look at what the data on stickers from different manufacturers might look like in a comparison table:

What to do if the sticker is missing or worn off

It's quite common for the factory label to be damaged, peeled off, or removed. This can occur due to prolonged use, exposure to high temperatures, or mechanical damage. In this case, finding the factory password simply by looking at the case becomes impossible.

However, this isn't a dead end. If the router is already configured and distributing internet, but you don't know the current password (which may have been changed), you can view it through the router's web interface. To do this, connect to it via cable or, if the device remembers your device, via Wi-Fi. Then, enter the IP address in the browser's address bar, usually 192.168.0.1 or 192.168.1.1.

⚠️ Note: Router interfaces are constantly being updated. Menu locations may vary depending on the firmware version. If you can't find the item you need, check the official instructions for your specific model on the manufacturer's website.

After logging in (you will need the administrator login and password, often this is admin/admin) you need to go to the wireless network section. Depending on the model, the path may look like this Wireless → Wireless Security or Wi-Fi → Basic SettingsThere in the field WPA/WPA2 Passphrase The current active password will be displayed. Many modern interfaces have an "eye" button next to the input field, allowing you to reveal hidden text.

Viewing a saved password on a connected computer

If a Windows computer is already connected to your Wi-Fi network, the operating system stores the access key in its settings. This eliminates the need to re-enter the password each time, but also allows you to retrieve it if you forget it. This method works even if the factory sticker on the router has long been lost.

To view the settings, open the Network and Sharing Center. In Windows 10 and 11, you can do this quickly by right-clicking the network icon in the system tray or through the Control Panel. Next, select the active connection, click the Wireless Network Properties button, and go to the Security tab.

The window that opens will contain the "Network Security Key" field. Initially, the characters are hidden by asterisks. To view the password, check the box next to "Show entered characters." The system may request administrator privileges to confirm this action.

• 🔍 Right-click on the Wi-Fi icon in the tray.
• 🖥️ Select "Open Network & Internet Settings" or "Network and Sharing Center".
• 🔗 Click on the name of your connection (blue text).
• 🛡️ In the status window, click "Wireless Network Properties".
• 👁️ Go to the "Security" tab and "Show entered characters".

For macOS users, the process is also quite simple. Using Keychain Access, you can find your network name, open its properties, and, by checking the "Show password" box, see the required character combination after entering your Mac user account password.

Using the command line to retrieve data

For more advanced users or in situations where the graphical interface is unstable, the Windows command line is an excellent tool. This method allows you to retrieve the password of any saved network without having to navigate through numerous menus. This is especially useful if you need to find the password for a network your computer has connected to in the past but is not currently connected to.

First, you need to run the command prompt with administrator rights. Enter cmd In Windows Search, right-click "Command Prompt" and select "Run as administrator." First, find out the exact network profile name if it differs from the SSID. Enter the command:

netsh wlan show profiles

Find the name of the desired network in the list. Then use the following command, substituting the name of your network:

netsh wlan show profile name="Your_Network_Name" key=clear

In the command output, find the "Security settings" section. There you'll find the "Key Content" line, which contains the password you're looking for. This method works reliably on all modern versions of Windows, starting with Windows 7.

Resetting your router as a last resort

If none of the above methods work—there's no sticker, none of the devices remember the password, and accessing the router settings is impossible (because the administrator password is lost or has been changed)—there's one last, radical option: a hard reset.

There is a button on the body of each router. Reset or WPS/ResetIt can be recessed into the housing to prevent accidental pressing. To reset the router, turn on the router, locate the thin hole marked "Reset," and press it with a paperclip or toothpick. Hold the button for about 10-15 seconds until the front panel indicators flash simultaneously or the router reboots.

After this procedure, the router will return to its original state. All provider settings, network names, and passwords will be reset. You'll be able to connect using the information on the factory sticker (or the default information in the manual if there's no sticker), but you'll have to reconfigure your internet access using your provider's username and password.

Frequently Asked Questions (FAQ)

Is it possible to find out a neighbor's Wi-Fi password from the sticker on the router?

No, this is impossible and illegal. The sticker is located inside the router owner's premises. Furthermore, attempting unauthorized access to someone else's network is a violation of computer privacy laws.

What should I do if the sticker contains a PIN, but the Password field is empty?

In most cases, for these devices (often TP-Link), the PIN code is the default password. Try entering it. If it doesn't work, the password was changed during initial setup.

I reset my router, but the password on the sticker doesn't work. Why?

You may be looking at the wrong sticker (for example, a warranty card) or the sticker belongs to a different model. Also, make sure you haven't mixed up the numbers (0 and O, 1 and I). If all else fails, the sticker may have been replaced by the manufacturer or chemically damaged.

Where can I find the password if my router is distributing internet, but I don't know it?

The easiest way is to check the settings of an already connected smartphone (on a rooted Android phone or via a sharing QR code) or computer, as described in the sections above. Logging into the router itself is not necessary for this.

Is it safe to use the password from the factory sticker?

Using the factory password on a regular basis is not recommended, as it is often simple and algorithmically known for a given model. An attacker could easily guess it. It's best to change the password to a complex, unique one consisting of letters and numbers immediately after purchase.
