How To Find the WiFi Password on Mac OS X

I‘ve MBP 13″ laptop. How can I find out the Wifi password on Mac OS X using command line and GUI options?

OS X stores your WiFI details including password in Keychain password management system. You can use this tool, if you do not remember the password of particular WiFi network on Apple Mac OS X. There are two methods to get the WiFI password as follows:

#1: Display the WiFi Password on Mac OS X Using CLI

You can use the security command. It is a command line interface to keychains and Security framework which stores your WiFI password and other information. Open the Terminal app and type the following command:

security find-generic-password -ga YOUR-ACCOUNT-NAME
security find-generic-password -ga SSID-HERE
security find-generic-password -ga YOUR-WiFi-Access-Point-Name-Here

In this example, find the Wifi password for Iphone4s access point (SSID):

security find-generic-password -ga Iphone4s | grep -i password

security find-generic-password -ga Iphone4s

You will be promoted to enter your own username and password as follows:

The System Keychain is a utility which securely stores all passwords and user IDs for a user and lets that user unlock them all with a single master password.
