The situation when you need to connect a new device to your home network, but the password is lost or forgotten, is one of the most common problems in home network administration. Network security key A password is a special set of characters that serves as a digital passcode for authorizing devices on your local network. Without this code, no smartphone, laptop, or smart speaker will be able to access the internet through your router, making it critically important to maintain.
Fortunately, modern operating systems and router hardware offer several reliable methods for recovering this information. You can find the saved password on an already connected Windows computer, view it in the router's web interface, or use the manufacturer's mobile app. In this article, we'll cover each of the available algorithms in detail so you can quickly restore network access.
Before you start technical manipulations, it is important to understand that encryption keys may differ depending on the chosen security standard, for example, WPA2 or more modern WPA3It's also worth considering that some internet providers set their default passwords on the bottom sticker of their equipment, which users often change, forgetting to write down the new values.
Finding a saved password in the Windows operating system
If a Windows laptop or desktop computer has previously connected to your wireless network, the operating system may have saved this key in its profile. This is the fastest method, requiring no access to the router's settings or physical access to the internet sharing device itself. The system stores this data in encrypted form, but allows the user to view it in plain text through standard menus.
First, you need to open the Network Control Panel. Press the key combination Win + R, in the window that appears, enter the command ncpa.cpl and press Enter. In the "Network Connections" window that opens, find the icon for your wireless adapter, right-click it, and select "Status." In the new dialog box, click "Wireless Network Properties," then go to the "Security" tab.
Here you'll see the "Network Security Key" field, which is hidden by asterisks by default. To see the characters, check the "Show entered characters" box. After doing this, the system will require administrator privileges to confirm the operation. Attention: If you do not have administrator rights on this computer, you will not be able to see the password using this method.
⚠️ Attention: On some enterprise Windows builds or when using certain group policies, access to the Security tab may be restricted by the system administrator. In this case, try using the command prompt.
An alternative method for advanced users is to use the command line. Open Terminal as administrator and enter the following command: netsh wlan show profile name="Your_Network_Name" key=clearIn the security information block, find the line "Key Contents," which will contain the password you're looking for.
Viewing the key through the router's web interface
The most universal method, which works regardless of the connected client type (Android, iOS, Windows, or Linux), is to access the router's settings. To do this, you'll need a browser and access to the local network. This means the device must be connected to the router either via cable or Wi-Fi (if the password is already saved on one of the devices). The login address is usually found on a sticker on the bottom of the device and most often looks like this: 192.168.0.1 or 192.168.1.1.
After entering the IP address in the browser's address bar, the system will ask for a login and password to access the control panel. By default, this is often a pair admin/admin, but if you've changed this information before and don't remember it, you'll have to perform a full reset of your router. After successful authorization, the interface may look different depending on the model, but the search logic remains the same.
You need to find the section responsible for your wireless network. It may be called "Wireless," "Wi-Fi," "Wireless Network," or "WLAN." Within this section, look for the "Security Settings" or "Wireless Security" subsection. This is where the "PSK Password," "WPA Pre-Shared Key," or "Security Key" field is located.
Below is a table with typical navigation paths for popular router brands to help you navigate the menu more quickly:
| Router brand | Menu section | Subsection | Field name |
|---|---|---|---|
| TP-Link | Wireless | Wireless Security | Wireless Password |
| ASUS | Additional settings | Wireless network | WPA-PSK key |
| Keenetic | My Networks and Wi-Fi | Home network | Wi-Fi network password |
| D-Link | Wi-Fi | Security settings | PSK encryption key |
Once you've found the password field, you can simply copy it or change it to a more complex one. Don't forget to click "Save" or "Apply" if you've made any changes, otherwise the new key won't take effect, and all devices will be disconnected from the network.
Using mobile apps and QR codes
Android and iOS smartphone owners can use built-in operating system features or router manufacturer apps to view saved networks. Android (version 10 and later) and iOS (version 16 and later) offer a convenient Wi-Fi QR code feature, which often also displays the password in plain text.
On Android, go to "Settings" -> "Wi-Fi" (or "Connections"). Tap the gear icon next to your network name or select "Share" (sometimes you need to scan your fingerprint or enter your unlock PIN). A QR code for connecting guests will appear on the screen. Below this code, you'll often see the text "Password: your_password" in small print. If there's no text, you can take a screenshot of the code and scan it with any QR code scanner app, which will display a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;, Where P - this is the key.
iPhone users can view the password by going to "Settings" -> "Wi-Fi" and tapping the information icon (the blue "i" in a circle) next to the active network. Next, tap the hidden "Password" field. The system will perform biometric verification (Face ID or Touch ID), after which the password will be displayed in clear text and can be copied.
⚠️ Attention: The option to view a password via QR code or biometrics is only available for networks the phone has previously connected to. This method won't work for new, unknown networks.
Also many router manufacturers such as Tenda, TP-Link or Xiaomi, have their own mobile apps (for example, Tether or Mi Home). If your router is linked to an account in such an app, you can open it, select your device, and view or change the password in the Wi-Fi settings section without logging in through a browser.
Physical sticker and factory settings
The most basic, yet often overlooked, method is to inspect the router's casing. Almost every modern device has an information sticker on the bottom or back panel. It contains the default (factory default) access details: the SSID (network name), the address for logging into the settings, and, most importantly, the PIN or password (security key).
This method will only work if you or anyone else hasn't previously changed the default password to their own. If the settings were reset using the button Reset, the password will revert to the one on the sticker. However, if the password was changed through the interface and forgotten, the sticker will no longer be helpful, as it only reflects the device's current state.
It's important to distinguish between two types of passwords that may appear on the sticker: the password for logging into the web interface (often labeled "Login Password" or simply "Password") and the password for connecting to Wi-Fi (may be labeled "Wireless Key," "WPA Key," or "Wi-Fi Password"). In modern models, these are often the same by default, but technically, they are different access keys.
What should I do if the sticker has worn off?
If the information on the sticker is illegible, try shining an ultraviolet light on it—sometimes factory markings will show through. You can also search for your router model online and download the manual, which may list the default passwords for that model, although these are usually unique to each router.
Resetting your router as a last resort
If none of the software methods work, and you don't remember the Wi-Fi password or the router settings, the last resort is a hard reset. This will restore the device to its factory settings, erasing all user settings, including the network name, Wi-Fi password, provider settings, and MAC filtering.
To perform a reset, find a small indentation on the router body with the inscription Reset or RestoreTake a paperclip or toothpick, press the button inside the hole, and hold it for about 10-15 seconds until the front panel lights flash simultaneously or the router reboots. After this, the device will operate according to the parameters specified on the factory label.
After the reset, you'll need to reconfigure your internet connection. You'll need your ISP credentials (username and password for PPPoE or Dynamic IP connection type), which should be included in your contract. Without these credentials, the router won't be able to broadcast the internet, even if Wi-Fi works with the factory password.

Frequently Asked Questions (FAQ)
Is it possible to hack someone else's Wi-Fi security key?
Most countries' laws strictly prohibit unauthorized access to other people's computer networks. Hacking someone else's Wi-Fi is illegal. This article describes only legal methods for restoring access. own networks or networks that you are officially authorized to access.
Why does the router say "Invalid network security key"?
This error occurs if the entered password doesn't match the one stored in the router's memory. Common causes include: Caps Lock is enabled, the wrong keyboard layout is selected (Russian instead of English), there are extra spaces at the beginning or end of the line, or the password has been changed by the network owner and your device is attempting to use the old key.
What is the difference between WPA2 and WPA3?
WPA2 — is an encryption standard that has been in use for over 15 years and is considered secure, but vulnerable to certain types of attacks. WPA3 — a newer standard that provides enhanced password protection against guessing and data encryption, even on open networks. For home use, we recommend choosing WPA3 or a mixed WPA2/WPA3 mode if all your devices support it.
How to create a strong security key?
A good password should be at least 12 characters long and include uppercase and lowercase letters, numbers, and special characters. Avoid obvious combinations like "12345678," your date of birth, or your phone number. Ideally, use a randomly generated password that can then be saved in a password manager.
Will resetting the router reset my provider's tariff settings?
Yes, a hard reset deletes all settings, including ISP connection parameters (PPPoE, L2TP, VLAN, etc.). After the reset, the internet will not work until you re-enter the authorization information provided by your service provider.
