Short Answer 
To view your Wi-Fi password using the Crosh terminal, you first open it by pressing Ctrl + Alt + T. Then, gain superuser access by entering the commands “shell” and “sudo su,” followed by navigating to the Wi-Fi configuration directory with “cd /home/root/etc/NetworkManager/system-connections” and displaying the password with “cat [Wi-Fi network name].”
Step 1: Open Crosh Terminal
To start the process of viewing your Wi-Fi password, you first need to access the Crosh terminal. You can do this by pressing the keys Ctrl + Alt + T simultaneously on your keyboard. This will open a new tab with the terminal where you can enter commands necessary for accessing network settings.
Step 2: Gain Superuser Access
Once the terminal is open, you’ll need to gain superuser access to view the Wi-Fi password. Type the command shell and press Enter. Follow this by entering sudo su and pressing Enter again. This step is crucial as it allows you elevated privileges needed to access the configuration files.
Step 3: Navigate and View Wi-Fi Configuration
Now that you have superuser access, it’s time to locate your Wi-Fi configurations. Type cd /home/root/etc/NetworkManager/system-connections and press Enter. Finally, to view your specific Wi-Fi password, type cat [Wi-Fi network name] (replacing [Wi-Fi network name] with the actual name of your network) and press Enter. The password will be displayed in the terminal.
