How Do I Find My Wep Key on a Mac?by Mario Calhoun ; Updated September 28, 2017
The Wired Equivalent Privacy (WEP) key on your Macintosh computer is the password used for your network that prevents unauthorized users from accessing your network. If you have misplaced your WEP key, you can find it in your Macintosh computer's Keychain Access application. This application stores and organizes all of your passwords, login IDs and certificates, and should only be used to retrieve lost passwords. To protect your private information, do not give out your system administrator password, as it is used to open Keychain Access.
Click “Go” at the top of your computer’s screen, and select “Utilities” from the drop-down menu. Alternatively, open the Applications folder in Finder and double-click the “Utilities” folder.
Double-click the “Keychain Access” icon to run the application. Click the “Login” tab under the “Keychain” section and double-click the name of the network you want to look up.
Click the “Attributes” tab and check the box next to “Show Password.”
Type your system administrator password in the dialog box that pops up, and click the “Allow” button. The password will appear in the field next to “Show Password.”
Click the red button in the upper-left corner of the window, and click the lock icon in the upper-left corner of the Keychain Access window to prevent changes from being made in the application.
Press the “Command” and “Q” button simultaneously to close the Keychain Access application.
