Where to Get a Wi-Fi Hardware Key: Finding the Password and PIN

Many users encounter a situation where they need to connect a new device to a wireless network, but the default password is lost or unknown. At this point, a screen prompts them to enter hardware key, which often causes confusion. This term can refer to either the password for the Wi-Fi network itself or a special PIN code for WPS technology, which allows you to connect without entering long characters.

Understanding the difference between these concepts is critical to successfully resolving the issue. If you confuse the WPS PIN with the Wi-Fi password, the router will return an authorization error and you won't be able to access the internet. In this article, we'll detail all the possible locations where this data is stored and how to extract it from various devices.

Most often, the information you need is found on a physical sticker on the device's casing or in the operating system settings if you're already connected to the network. However, there are nuances to be aware of for different router manufacturers and Windows and Android operating system versions.

Differences between a Wi-Fi password and a WPS key

The first step to solving the problem is to clearly distinguish between the concepts. Wi-Fi password (Wireless Password) is a string of characters used to encrypt traffic using the WPA2 or WPA3 protocols. This is what you enter when you first connect your smartphone or laptop to the network. This code can be changed by the user at any time through the router's web interface.

In turn, WPS hardware key (Wi-Fi Protected Setup) is typically an 8-digit numeric code. It's designed to simplify connecting devices without the need to enter a complex password. WPS technology allows you to connect simply by entering this PIN on the device or pressing a button on the router. It's important to understand that these codes are not interchangeable.

• 🔑 Network password: It can contain letters, numbers and special characters, and is usually from 8 to 64 characters long.
• 🔢 WPS PIN code: Strictly 8 digits, often printed on the device label.
• 📡 Purpose: A password protects the network from hacking, while a PIN code is used for quick authorization of trusted devices.

In some older Windows interfaces or virtual adapter drivers, the term "hardware key" may be used synonymously with a MAC address or encryption key, but in 95% of cases, it actually refers to an access password. If the system specifically asks for a "key," try entering your Wi-Fi password. If a PIN is required, look for an eight-digit number.

⚠️ Warning: WPS technology is considered vulnerable to brute-force attacks. If you don't use the Quick Connect feature, we recommend disabling WPS in your router settings to improve your network security.

Find the key on the router body and in the documentation

The most reliable and quick way to find the necessary data is a physical inspection of your router. Telecom equipment manufacturers are required to place factory settings on a special sticker. This is usually located on the bottom of the case, but on some models, such as vertical towers from Asus or Keenetic, may be located on the back panel near the ports.

On the label you are interested in the fields marked as WPS PIN, PIN Code or Wireless PasswordFor default networks, the password is often the same as the device's serial number or the "admin" combination. However, if you or the previous owner has changed the settings, the information on the sticker may no longer be valid for logging into the network, although the WPS PIN often remains the factory default.

If the sticker is worn off or missing, refer to the original packaging or the paper instructions that came with your device. User manuals often provide an approximate label with the factory data for a specific model. This information can also be found on the manufacturer's website by entering the exact device model listed on the label.

How to find the key through the router interface

If physical access to the sticker is impossible, but you can connect to the router via cable or Wi-Fi from another device, you can access the information through the web interface. To do this, enter the gateway IP address in your browser. Standard addresses are: 192.168.0.1, 192.168.1.1 or a domain name, for example, my.keenetic.net.

After entering your administrator login and password (often admin/admin, unless you've changed them), navigate to the wireless network section. Interfaces vary by manufacturer, but the logic is the same: look for the "Wi-Fi," "Wireless," and "Wireless Network" tabs. The current password (SSID Key) and WPS status/code will be displayed there.

In some cases, the password may be hidden behind asterisks. To see them, you can often click the "eye" icon next to the input field or use the "Show symbols" function. For WPS, the PIN is usually displayed in plain text in the corresponding menu subsection.

Don't forget to save your changes if you decide to change your password to a more complex one. After changing the key, all connected devices will require re-authorization with the new value.

Viewing a saved key in Windows

The Windows operating system stores passwords for every network your computer has ever connected to. This is the easiest way to restore access if you have a PC that's already connected to the desired Wi-Fi network or has connected previously. The data retrieval process varies depending on the OS version.

In Windows 10 and 11, use the graphical interface to open "Settings" → "Network & Internet" → "Wi-Fi" → "Manage known networks." Select the desired network and click "Properties." In the window that opens, you'll see a "Network security key" field, where you can click the "Show characters" button.

For a deeper search, or if the graphical interface doesn't work, you can use the command line. Run cmd As an administrator, run the command to display the network profile. This will allow you to view the password in plaintext if it's stored on the system.

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

In the command results, find the line "Key Content." This value is the password you're looking for. This method works even if the network is not currently active, as long as the profile is saved in memory.

What should I do if the netsh command returns an error?

An error may occur if the network name is entered incorrectly. To find the exact name of a saved profile, enter the command netsh wlan show profiles. A list of all networks will appear in the "User Profiles" column. Use the name exactly as it appears in the list, including capitalization and spaces.

Viewing your password on Android and iOS

Modern mobile operating systems also allow you to view saved passwords, although this functionality appeared relatively recently. On devices Android (version 10 and above) you need to go to Wi-Fi settings, select the desired network, and click the gear or information icon. There's often a "Share" button or a QR code there.

When generating a QR code for a guest, the password is often displayed in text below or within the code itself. If there is no text, you can scan the QR code with another phone with a scanner, and the device will display the password in a notification.

On devices Apple (iOS 16 and later, iPadOS 16+) The process is even simpler. Go to "Settings" → "Wi-Fi" and tap the blue "i" icon next to the network name. In the "Password" field, tap the hidden dots—the system will ask for Face ID or Touch ID, then display the password, which you can copy.

• 📱 Android: Settings → Wi-Fi → Gear → QR code / Share.
• 🍏 iOS: Settings → Wi-Fi → (i) → Tap the Password field → FaceID.
• 🔒 Safety: Biometric authentication or screen unlock PIN is required to view.

⚠️ Note: On older versions of Android (below 10) and iOS (below 16), there is no built-in way to view passwords. In these cases, root access (for Android) or jailbreaking (for iOS) may be required, which is not recommended for security reasons.

Table: Location of keys on devices of different brands

The location of access key information may vary depending on the hardware manufacturer and firmware version. Below is a summary table to help you navigate the interfaces of popular brands.

Please note that interfaces are subject to update. If you don't see the above items, look for sections with similar names or consult the official manual. Some newer TP-Link and Tenda models use cloud management via an app, where WPS settings can be located in a separate "Tools" or "Advanced" section.

Restoring access if all data is lost

If the password has been changed, the sticker has been lost, and no devices remember the network, a radical but effective solution remains: resetting the router to factory settings (hard reset). This will return all settings, including the Wi-Fi password and WPS PIN, to the values ​​indicated on the factory sticker.

To perform a reset, find the small hole on the case with the inscription Reset or RestoreWith the router turned on, gently press it with a paperclip or toothpick and hold it there for 10-15 seconds until all the lights flash. After rebooting, the network will be named as indicated on the sticker, and the password will be the default.

You'll need to reconfigure your router to access the internet, so make sure you have your ISP contract handy.

Once access has been restored, it is strongly recommended that you immediately change the default password to a unique and complex one to protect your network from unauthorized access by neighbors and intruders.

Frequently Asked Questions (FAQ)

Is it possible to select a Wi-Fi hardware key programmatically?

There are security auditing programs (such as Aircrack-ng) that theoretically allow intercepting and brute-forcing keys, but this requires extensive knowledge, specialized equipment, and considerable time. For ordinary users, legal recovery methods (via router or OS settings) are the only reliable solution. Using other people's networks without permission is illegal.

What to do if the WPS PIN code does not work?

If the 8-digit code on the sticker doesn't work, the WPS function may be disabled in the router settings or blocked by an antivirus program. Also, on some models (for example, older D-Link or TP-Link models), the PIN code may be generated dynamically each time you turn it on, and you only need to check the current one in the web interface when connecting.

Is a MAC address a hardware key?

No, a MAC address is a unique identifier for a network interface, consisting of 12 hexadecimal characters. Although some providers use MAC address binding to provide internet access, it is not the password (key) for connecting to a Wi-Fi network.

Where can I find the key if the router is provided by my provider (Rostelecom, Dom.ru)?

On rented routers, the stickers are often covered with the provider's logo. Try turning the device over or looking under the removable battery (if present). If there's no sticker, the password is often printed on a separate card in the contract or can be found in the subscriber's personal account under "Equipment."

Is it possible to find out a Wi-Fi password using the command line on someone else's PC?

Technically, if you have physical access to a computer that has previously connected to the network and administrator rights, you can use the command netsh (described above) to view the saved password. However, using this method on someone else's device without the owner's permission violates digital ethics and may be considered an attempt at unauthorized access.
