You can find it on your device if you forget a Wi-Fi password or need to share it. Here’s how to do it on a Chromebook.
/wp:paragraph
wp:paragraph
Unfortunately, Chrome OS does not make this easy. Most devices show saved Wi-Fi passwords, but Chromebooks do not—at least not by default. You must enable “Developer Mode.”
/wp:paragraph
wp:paragraph
Developer Mode gives more features, but it has risks. You must fully reset your Chromebook to turn it on.
/wp:paragraph
wp:paragraph
Google does not support this mode, so you will not get official help if problems happen. It is not for everyday users.

If you want to enable Developer Mode, we have a step-by-step guide. Once it is on, follow these steps to see Wi-Fi passwords.

Press Ctrl + Alt + T to open the Crosh command prompt.
/wp:paragraph
wp:paragraph
Welcome to Crosh, the Chrome OS developer shell.
/wp:paragraph
wp:paragraph
If you got here by mistake, don’t panic! Just close this tab and carry on.
/wp:paragraph
wp:paragraph
Type ‘help’ for a list of commands.
/wp:paragraph
wp:paragraph
If you want to customize the look/behavior, you can use the options page.
/wp:paragraph
wp:paragraph
Load it by using the Ctrl-Shift-P keyboard shortcut.
/wp:paragraph
wp:paragraph
crosh>
/wp:paragraph
wp:paragraph
Then, enter these commands and press Enter after each one:
/wp:paragraph
wp:paragraph
shell
/wp:paragraph
wp:paragraph
sudo su
/wp:paragraph
wp:paragraph
cd home/root
/wp:paragraph
wp:paragraph
ls
/wp:paragraph
wp:paragraph
crosh> shell
/wp:paragraph
wp:paragraph
chronos@localhost / $ sudo su
/wp:paragraph
wp:paragraph
localhost # cd home/root
/wp:paragraph
wp:paragraph
localhost /home/root # ls
/wp:paragraph
wp:paragraph
A code string will appear. Copy it, then enter
/wp:paragraph
wp:paragraph
cd
/wp:paragraph
wp:paragraph
Paste the code and hit Enter.
/wp:paragraph
wp:paragraph
localhost /home/root # ls
/wp:paragraph
wp:paragraph
localhost /home/root # cd
/wp:paragraph
wp:paragraph
Now, enter this command:
/wp:paragraph
wp:paragraph
more shill/shill.profile
/wp:paragraph
wp:paragraph
Type it, then hit Enter.
/wp:paragraph
wp:paragraph
It will show details about your network. Find the line with “Passphrase=rot47:”. Copy the random text after it. That is the encrypted password.
/wp:paragraph
wp:paragraph
Type the following command:
/wp:paragraph
wp:paragraph
echo randomtexthere | tr ‘!-~’ ‘P-~!-O’
/wp:paragraph
wp:paragraph
Press Enter. Change “randomtexthere” to the copied text.
/wp:paragraph
wp:paragraph
You will now see the Wi-Fi password without encryption. This process is complicated for something as basic as a Wi-Fi password.
/wp:paragraph
wp:paragraph
Other devices, like Android phones, have more straightforward ways to find Wi-Fi passwords.
