Once you have Command Prompt open with administrative privileges, you can use the following command to list all saved Wi-Fi profiles:
netsh wlan show profiles
This command will display a list of all the Wi-Fi networks that your computer has previously connected to. Note the name of the network for which you want to retrieve the password.
Next, use the following command to display the password for the specific Wi-Fi network, replacing “Your_Wi-Fi_Network_Name” with the actual name of your Wi-Fi network:
netsh wlan show profile name="Your_Wi-Fi_Network_Name" key=clear
This command will display detailed information about the specified Wi-Fi profile, including the password in plain text. Look for the line labeled “Key Content” to find your Wi-Fi password.
It is important to note that the key=clear parameter is essential for displaying the password in plain text. Without this parameter, the command will not reveal the password.
Deciphering the `netsh` Output
The output of the netsh wlan show profile command contains a wealth of information about your Wi-Fi network profile. Aside from the “Key Content” which reveals the password, the output includes details such as:
- Name: The name of the Wi-Fi network (SSID).
- Interface name: The name of the wireless network adapter used to connect to the network.
- Connection mode: Indicates whether the connection is a manual or automatic connection.
- Authentication: The authentication method used by the network (e.g., WPA2-Personal).
- Cipher: The encryption algorithm used by the network (e.g., CCMP).

Retrieving Your Wi-Fi Password on macOS
macOS provides a different set of tools for managing Wi-Fi networks and retrieving passwords. The primary tool for this purpose is the security command.
Utilizing the `security` Command
The security command is a command-line tool for managing the macOS keychain, which stores passwords, certificates, and other sensitive information. Wi-Fi passwords are stored in the keychain, making the security command the key to retrieving them.
To use the security command, open Terminal. You can find Terminal in the /Applications/Utilities folder.
Once Terminal is open, use the following command to retrieve the Wi-Fi password, replacing “Your_Wi-Fi_Network_Name” with the actual name of your Wi-Fi network:
security find-generic-password -wi-fi "Your_Wi-Fi_Network_Name" -ga
This command instructs the security command to search the keychain for a generic password associated with the specified Wi-Fi network and then display the password.
If the command is successful, it will prompt you for your administrator password. Enter your password and press Enter. The Wi-Fi password will then be displayed in plain text.
Note that the security command requires administrator privileges to access the keychain and retrieve password information.
Understanding Keychain Access
The macOS keychain is a secure repository for storing sensitive information. Access to the keychain is controlled by user accounts and permissions. When you attempt to retrieve a Wi-Fi password using the security command, the system prompts you for your administrator password to verify that you have the necessary privileges to access the keychain.
Alternative GUI Method on macOS
While the command line is efficient, macOS also allows password retrieval through Keychain Access, a graphical utility. Open Keychain Access (found in /Applications/Utilities/). Search for the Wi-Fi network name, double-click on it, check the “Show Password” box, and authenticate with your administrator password.

Linux distributions often rely on network management tools like nmcli (NetworkManager Command Line Interface) or configuration files to store Wi-Fi passwords. The method for retrieving your Wi-Fi password depends on the specific distribution and network configuration.
Using `nmcli`
nmcli is a command-line tool for managing NetworkManager, a popular network management service used by many Linux distributions.
To use nmcli to retrieve your Wi-Fi password, open a terminal.
First, list the available Wi-Fi connections using the following command:
nmcli con show
This command will display a list of all the Wi-Fi connections that your system has previously connected to. Note the name of the connection for which you want to retrieve the password.
Next, use the following command to display the password for the specific Wi-Fi connection, replacing “Your_Wi-Fi_Connection_Name” with the actual name of your Wi-Fi connection:
sudo nmcli con show "Your_Wi-Fi_Connection_Name" | grep psk
This command will display the line containing the password (PSK – Pre-Shared Key). You may need to enter your sudo password.
The sudo command is necessary because accessing network configuration information typically requires root privileges.
Exploring `nmcli` Output
The output of the nmcli con show command provides valuable details about each network connection, including:
- NAME: The name of the connection profile.
