how to find wifi password on chromebook

Can’t remember the password of the Wi-Fi network your Chromebook is connected to? No worries, we’ve got you covered! In this guide, we’ll show you how to easily find Wi-Fi passwords on your Chromebook using the Google Chrome web browser. Let’s get started!

Find Saved Wi-Fi Passwords via Google Chrome

Open Google Chrome on your Chromebook and follow these simple steps:

  1. Type chrome://sync-internals in the address bar and press Enter.
  2. Open the Search tab, type wifi in the search box, and press Enter on your keyboard.

The results/nodes with “psk” at the end are the saved Wi-Fi networks on your Chromebook. The alphanumeric characters before the “psk” are the encrypted Wi-Fi network name or SSID (service set identifier).

To decrypt the network name/SSID, you can use online hex decoder tools like Base64 or JavaInUse. Here’s what you need to do:

  1. Select an entry on the sidebar and copy the encrypted network name in the “NAME” row.
  2. Paste the copied text in the hex decoder tool to decrypt/see the network name/SSID.

Next, let’s decrypt the network passcode or password:

  1. Return to the Wi-Fi network’s page on Chrome’s “Sync internals” menu and copy the text in the “passphrase” row.
  2. Paste the copied text in the online hex decoder tool to see the Wi-Fi network’s password.

Check Chromebook Wi-Fi Password in Developer Mode

Please note that this method requires enabling Developer Mode and running multiple commands in the Chrome Shell terminal. Follow these steps with caution:

  1. Select the time in the bottom-right corner of the screen to open your Chromebook’s system tray.

  2. Select the Power icon to shut down your Chromebook. Wait for 10-15 seconds before proceeding to the next step.

  3. Press and hold the Esc + Refresh + Power buttons simultaneously.

  4. Release all three buttons when your Chromebook displays a recovery screen with the “Please insert a recovery USB stick or SD card” message.

  5. Press Ctrl + D to enable Developer Mode.

  6. Afterward, press Enter to turn off OS verification.

Disabling OS verification activates Developer Mode, allowing your Chromebook to boot non-Google operating systems. Wait while your Chromebook transitions into Developer Mode — the operation may take 5-10 minutes.

  1. Press Ctrl + D on the “OS verification is OFF” screen to boot your Chromebook.
    Alternatively, wait for 10-20 seconds, and your Chromebook will automatically boot into Developer Mode after making a loud beep.

Now that your Chromebook is in Developer Mode, let’s proceed to find passwords for previously connected Wi-Fi networks:

  1. Press Ctrl + Alt + T to launch the Chrome Shell command-line interface/terminal.
  2. Type or paste shell in the terminal and press Enter.
  3. Afterward, type/paste sudo su in the following line and press Enter.
  4. Type cd home/root and press Enter.
  5. Type ls, press Enter, and copy the code string in the next line.
  6. Next, type or paste more shill/shill.profile and press Enter.

    The characters represent the encrypted password for the Wi-Fi network. Run the command in the next step to decrypt the network password.

  2. Type echo copied-text | tr '!-~' 'P-~!-O' and press Enter. Replace copied-text with the encrypted password/characters you copied in step #7.

You should see the password for the Wi-Fi network on the next line.

Find Wi-Fi Passwords on Other Devices
