I need to know the wifi password for my computer because I need to connect another device like my iPhone or iPad to the network. There is no way I ever remember that password any wifi network other than my own, so I have to get it from somewhere else. If your computer is already connected to the network, it makes perfect sense to just find the key from there.

To reset your Mac’s password, open the Keychain program and select the “reset password” option.

Find Stored WiFi Password using Keychain

Now, open the Keychain by going to the following:

  1. Open Keychain by either searching for it in Spotlight or going to Applications – Utilities.
  2. In the Keychain, click on the “Open” button.
  3. Now, in the Open dialog, type your password and click on the “OK” button.
  4. Now, in the main Keychain window, you will see a list of your current items: your keychains and passwords!

If you want to change which items are displayed in the left hand column, you can do so by selecting the item in the right hand column and then clicking on the Change button.

To find the passwords for wireless networks, you can click on System in the top left-hand menu. These should all be categorized as AirPort network passwords. ..

Now to view the actual password, go ahead and double-click on the wireless network of your choice. You’ll get a pop up window that’ll list the name of the network and some other details. At the bottom, you’ll see the Show password check box. Go ahead and check that.

OS X wants to make changes to your password so type in an administrator’s name and password to allow this.

OS X Mavericks requires you to type in your username and password for the computer again. I’m not sure why it required twice, but that’s how it’s working on Mavericks at this point. Once you do this, you’ll finally get the saved wifi password!
