Get all wifi passwords

Getting Saved Wifi Passwords using Python

Usually while connecting with the wifi we have to enter some password to access the network, but we are not directly able to see the password we have entered earlier i.e password of saved network. In this article, we will see how we can get all the saved WiFi name and passwords using Python, in order to do this we will use subprocess module of python.
Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet.
The subprocess module present in Python(both 2.x and 3.x) is used to run new applications or programs through Python code by creating new processes. It also helps to obtain the input/output/error pipes as well as the exit codes of various commands.

Steps for Implementation :
1. Import the subprocess module
2. Get the metadata of the wlan(wifi) with the help of check_output method
3. Decode the metadata and split the meta data according to the line
4. From the decoded metadata get the names of the saved wlan networks
5. Now for each name again get the metadata of wlan according to the name
6. Start try and catch block and inside the try block, decode and split this metadata and get the password of the given wifi name
7. Print the password and the wifi name and print blank if there is no password
8. In except block if process error occurred print encoding error occurred

Below is the implementation

wifipasswords

Retrieve and save all WiFi networks and passwords on the device.
On windows uses the netsh subprocess.
On linux reads the NetworkManager files or wpa_supplicant.conf.

there is also a GUI version of this tool that can be found here — WifiPasswords-GUI

NOTE: requires sudo privileges on linux only if NetworkManager is not used.

NOTE: Macos requires admin authentication for each password read, this can result in a lot of prompts for the get_passwords() function. I am currently looking for a solution for this.

Features

• Importable as a package or able to be run directly on the command line
• Tested in Python 3.6 — 3.10
• Tested on Windows 10, Ubuntu 18 — 20.04, Debian Buster, macOS 10.13 (High Sierra) and macOS 10.14 (Mojave)
• Returns WiFi passwords as a dictionary
• Able to show visible wifi networks
• Able to show currently connected SSID
• Able to show current DNS config
• Able to show known SSIDs and find single network passwords
• Can save networks as JSON or wpa_supplicant.conf file

Installation

Installed via pip using: pip install wifipasswords

Usage

Provides a command line interface callable after installation with:

To see command line options run wifipasswords -h

Packaging as EXE

Can be packaged to an EXE on windows with:
pyinstaller —clean —noconsole —onefile -i wifipasswords_exe.py

The wifipasswords_exe.py file is the same as the main.py file in the package except will pause after console output is finished to prevent the terminal from auto-closing if the EXE is run directly.

Testing

Test locally with pytest -v ./tests Currently github test runners do not have nmcli interface to access wifi data so test locally.

5 Ways To Find All Saved Wifi Passwords In Windows, MacOS & Android

If you want to find all the saved wifi passwords in Windows 10, look no further. We provide two easy ways to find all saved Wifi passwords in Windows.

Wi-Fi is extensively used to connect to multiple networks at different times and places. Be it a coffee shop, a free Wi-Fi hotspot, office wireless network, or a home network, Wi-Fi is used everywhere. Windows 10 and Windows 11 can remember the settings of multiple Wi-Fi networks, including their network security keys.

Quick fix: How to see Wifi password in Windows

To view the wireless password on Windows, open Network Connections from the Control Panel, right click on the computer’s WiFi adapter, and then select Status > Wireless Properties. Select Show Characters to display the password in plain text.

Over time, it becomes difficult to remember or even save passwords for all the Wi-Fi networks you have connected to and saved in the past. Rather than trying to hunt down passwords from sysadmins, technicians, or using other ways, if you forgot the Wi-Fi password, Windows gives multiple options to see the saved Wi-Fi passwords.

View WiFi password on Windows 10/Windows 11

View Active WiFi Password From Wireless Properties

Windows 10/11 provides a simple way to see the password for your current WiFi connection. Just follow the steps below to see your current WiFi password:

1. Open the Network Connections page in the Control Panel by typing in ncpa.cpl in Run.
   
2. Right-click on the Wi-Fi adapter and click Status from the context menu.
   
3. Click Wireless Properties to open WiFi network properties.
   
4. Go to the Security tab and check the box next to “Show characters” to reveal your current Wifi password.
   

You will now see the WiFi password in the text field labeled “Network security key.”

This method only works for active connections. That means if you are not connected to a Wi-Fi network, you will not be able to use this method to view the network security key or password. To do this, you will need to follow the steps given in the next section.

Find All WiFi Passwords Saved in Windows 10/11

What if you want to find all the saved Wifi passwords on your Windows computer? There are five ways to find all the saved Wifi passwords in Windows. Let’s discuss both of them.

View WiFi Passwords Using Command Prompt

To see all the Wifi passwords, you will need to run some commands in the command prompt.

1. Open Command Prompt with administrative rights.
2. Run the following command to show all the Wifi profiles saved on your computer:
   netsh wlan show profiles

   Note the profile for which you want to see the password.

3. Now run the following command to reveal the Wifi password content of a profile:
   netsh wlan show profile name=WifiConnectionNamekey=clear
   Replace WifiConnectionName with Wifi SSID, which you can find from the above mentioned command.

The command above will reveal the password for the selected WiFi SSID in front of “Key content,” as in the image below:

If you only want to see the password omitting all other details, you can run the following command instead:

netsh wlan show profile name=WifiConnectionName key=clear | find /I "Key Content"

You can check all the WiFi passwords saved on your computer using the same command. Just replace the profile name with a different one.

See Wifi Password For A Specific Network

If you want to find the Wifi password of a specific network only, follow the instructions below:

1. Open Command Prompt in administrative mode.
2. Run the following command:
   netsh wlan show profiles
   
   This command will list all the saved Wifi profiles on the computer. Copy the network profile you want the password for.
3. Run the following command:
   netsh wlan show profile name=NetworkProfileName key=clear
   Replace NetworkProfileName with your copied network name.
   

This will show the Wifi password in plain text in front of “Key Content.”

Get a List of Saved WiFi Passwords Using PowerShell

The same commands listed above also work in PowerShell. But if you want to list all the passwords in a nice table in PowerShell, you can run the following command.

(netsh wlan show profiles) | Select-String "\:(.+)$" | % | % <(netsh wlan show profile name="$name" key=clear)>| Select-String "Key Content\W+\:(.+)$" | % | %> | Format-Table -AutoSize

You can also download the following PowerShell script and run it on any computer to get a list of saved Wifi passwords.

Once downloaded, right-click the file and click Run with PowerShell.

If you want to use a visual medium, you can check out a few software that can do the job for you.

View All Saved Wifi Passwords Using WiFi Password Revealer

If you are not comfortable with using the Windows command line, you can use third-party software called “Magical JellyBean Wifi Password Revealer” which will retrieve all the Wifi passwords saved in Windows.

You just have to download Wifi password revealer, install and run it. No configuration is required.

You can select any Wifi connection and press Ctrl + Alt + C shortcut keys to copy the password in the clipboard.

View All Saved WiFi Passwords Using WirelessKeyView

WirelessKeyView is a portable application from NirSoft, which displays detailed information about each wireless network saved on the computer. It’s a very small tool and a very handy one, especially for sysadmins.

Unzip the zip file and run WirelessKeyView.exe. This will run the app without installation.

Note: Windows Defender detects WirelessKeyView as malware but it is pretty safe. You will need to whitelist the executable before it can be run on your computer.

If you are using Windows Server 2003 or Windows XP, the actual Wifi password will not be shown but it will be shown in HEX form. The same HEX password can be used to activate Wifi on any other device.

How to See WiFi Password on MacOS

You can also check your Wifi password on Apple MacOS. Follow the instructions given below to see it:

1. Press the Command button + Space bar on your keyboard to open Spotlight and type in “keychain access” to perform a search.
2. Launch the Keychain Access app.
3. From the app, search for the WiFi profile from the search bar and then double-click it.
4. From the pop-up window, check the box next to “Show password.”

You will now see the password in the text field in front of the checkbox.

How to See WiFi Password on Android

If you are on an Android device, here is how to view the password for a saved Wi-Fi profile:

1. Navigate to the following:
   Settings >> Wi-Fi and Network >> Wi-Fi
2. Here, scroll down and click Saved Networks.
   
3. On the next page, click on the Wi-Fi profile that you want to see the password for.
   
4. Here, click Share.
   
5. You will now be asked to verify yourself through a biometric or a PIN/pattern identification (if applied to your phone).
6. On the next page, you shall find the password to the Wi-Fi profile below the QR code.
   

How to See WiFi Password on iPhone

Apple’s iPhones are designed to ensure maximum security. That is why, at the time of writing this post, iPhones do not allow you to view your WiFi password in plain text. Rather, they only allow you to share it with other iPhones.

However, if you sync your WiFi passwords with your iCloud Keychain, you can view your saved network password on your MacOS (which also needs to be synced) using the given method above.

Closing Words

With increasing security, all operating system manufacturers are taking the necessary precautions to secure your intellectual property. That is why Android asks you to authenticate yourself before revealing a WiFi password, and Apple does not allow it at all. This is because a device connected to the same wireless network as yours can infiltrate your network and any device on it.
