There are situations when we want to find the saved Wi-Fi passwords that we once typed in our Mac. For instance, maybe you want to enter that same Wi-Fi password on another Mac device. If you find yourself in a situation like this and you want to find a saved Wi-Fi password on your Mac, you should know that there is more than one way to obtain it. However, the simplest and most convenient way to do this is to use the Keychain Access app on your Mac. Remember that you need to be logged in as an Administrator to get access to this app.
The Keychain Access is the app where Mac keeps the logins and passwords for every system function and websites. There is no doubt that this is one of the most important features of Macs.
Using Keychain Access
Simply go to the Applications tab and use the Utilities folder. Open it with a click and focus on the top left corner. This is where you will find four Keychains: iCloud, login, System Roots, and System. Click the System folder.
Select the Wi-Fi network
The next step is to click the Kind header located in the center of the tables. Arrange the items in an alphabetical order and locate the Airport network password item. On the left side, you will find your unique Wi-Fi network name or SSID. This is where you will find the rest of the stored Wi-Fi password if you have stored more than one password.
Use the Wi-Fi network entry
Once you identify your network, double-click on it and you will notice a new box. Find the Show password button and after typing your username and Mac password, your Wi-Fi password will become visible. You can write down or simply copy and paste your password.
While you are there, you can also change your password which might be a good option in case you are forgetting it.
Remember that you should update your password from time to time for security reasons. Whenever you want to change or find your saved Wi-Fi password on a Mac, use Keychain Access.
