How To Find Saved Wi-Fi Passwords in Ubuntu and Other Linux Distributions

When you connect to a wireless network using WPA or WPA2-PSK, Ubuntu saves the password to your system when you use the “connect automatically” option.

You may find yourself in a situation to know the Wi-Fi password. For example, if you need to provide the password to a visitor and you have not noted it down elsewhere.

Thankfully, all the network settings are stored properly and can be retrieved along with wireless password anytime you want.

I’ll show you both GUI and command line ways to see the saved WiFi passwords in Ubuntu and hopefully other Linux distributions.

Method 0: Use nmcli command to get password of currently connected network

This method should work on all Linux distributions that use network-manager. You just have to use this single command to get the details of the currently connected wifi network. You also get a QR code that can be shared with other people to connect to the network.

Ubuntu Wifi Password 1

Here, in the Wi-Fi tab, you’ll find a list of available WiFi networks and the ones you’ve connected to in the past. Click on the gear icon in the row corresponding to the network whose password you want to find.

In the Security tab and check the Show Password button to reveal the password.

That works for the currently connected networks. What about the networks to which you had connected in the past but that are not available anymore?

See all the previously connected networks (and their password)

In Ubuntu and other distributions using the GNOME desktop, you get an Advanced Network Configuration GUI tool.

When you start this tool, it shows all the networks that you had connected to previously. You can select the desired one and then click on the gear symbol at the bottom to access its settings.

It will give you the same interface you had seen earlier. Go to the Wi-Fi Security tab and click on the show password to see the password that you had used to connect to the said network.

Method 2: Finding saved WiFi password via the terminal

Ubuntu uses Network Manager to handle network related settings. These settings can be found in the /etc/NetworkManager directory.

The details of networks you have connected to in the past are stored in separate files in the sub-directory /etc/NetworkManager/system-connections.

In the associated file, the password for the network connection can be found under the wifi-security section, in the line that starts with psk.

sudo cat /etc/NetworkManager/system-connections/.nmconnection

Replace with the name of the desired WiFi network and make sure there is a “\” before every space in the network’s name (if any).

Как посмотреть сохраненные пароли WiFi в Ubuntu Linux

Посмотреть пароль WiFi в Ubuntu

Когда мы подключаемся по WiFi к какой-нибудь сети, то обычно вводим пароль и сохраняем его, чтобы дальнейшие подключения к данной сети выполнялись автоматически. Введенный пароль сохраняется в системе.

Рассмотрим, как посмотреть сохраненные пароли для WiFi соединений в Ubuntu Linux.

Просмотр паролей WiFi через настройки системы

Запуск Параметров системы

Пароль WiFi в Ubuntu Linux можно посмотреть через Параметры системы. Чтобы открыть Параметры системы вы можете кликнуть по иконке WiFi на панели в области уведомлений, и в открывшемся окошке нажать кнопку с символом «настроек».

Список сетей WiFi

В окне Параметров системы перейдите на вкладку Wi-Fi и в списке сетей нажмите на значок «настроек» для той сети, пароль которой вы хотите посмотреть.

WiFi пароль

Откроется окно настроек выбранной WiFi сети. Перейдите на вкладку Безопасность и поставьте галочку в поле Показывать пароль . Пароль от данной Wi-Fi сети отобразится в текстовом поле:

Просмотр паролей WiFi из командной строки

Теперь рассмотрим, как посмотреть пароль WiFi сети из командной строки.

Настройки WiFi соединений сохраняются в конфигурационных файлах, хранящихся в директории /etc/NetworkManager/system-connections . В этих же файлах прописаны пароли от WiFi соединений.

Выполним следующую команду, чтобы найти сохраненные WiFi пароли:

sudo grep psk= /etc/NetworkManager/system-connections/*

В результате получим одну или несколько строк для каждого сохраненного WiFi соединения. В конце каждой строки будет запись вида psk=пароль

Просмотр WiFi паролей из командной строки

Вы также можете найти пароль внутри конфигурационного файла соответствующей WiFi сети. Пример файла с настройками WiFi-соединения /etc/NetworkManager/system-connections/НазваниеСети :

How to find the saved Wifi Password in Ubuntu

I connected my laptop with my home Wifi connection but now I forget the password and I want to login on my mobile device as well. Can you tell me how can I check my saved password so that I can use it on my mobile? Or do I need to change the Wifi Password by accessing the router’s settings?

Open up a terminal ( Ctrl + Alt + t ) then issue:

cd /etc/NetworkManager/system-connections ls -la 

Now just cat out whichever file matches the connection you need to view:

sudo cat 'my_cool_network' # you MUST use sudo as file is root owned. quote if file name contains spaces 

In output look for something like this:

[wifi-security] auth-alg=open key-mgmt=wpa-psk psk=ele55Hroad 

As you can see my WiFi password is ele55Hroad

Above works on Ubuntu 18.10+

One-liner

sudo grep --with-filename psk= /etc/NetworkManager/system-connections/* 
$ sudo grep --with-filename psk= /etc/NetworkManager/system-connections/* /etc/NetworkManager/system-connections/SHAW-999999:psk=99999A999999 /etc/NetworkManager/system-connections/SHAW-999999-5G:psk=99999A999999 /etc/NetworkManager/system-connections/SHAW-999999-5G:psk=999999999999 

After » system-connections/ » you will see your WiFi network name. EG » SHAW-999999 «. Then you will see your password after » :psk= «. EG » 99999A999999 «. WiFi network name and password were redacted in case my neighbour is hoping for a free bus ride 🙂
