Forgetting a Wi-Fi password on your Mac can be a bit of a challenge, especially if you have saved multiple networks and want to remove a specific one. Whether you’re trying to remove an old network, troubleshoot connectivity issues, or simply want to start fresh, this article will walk you through the steps to make your Mac forget a Wi-Fi password.
Understanding Wi-Fi Password Storage on Mac
Before diving into the process of forgetting a Wi-Fi password, it’s essential to understand how Macs store Wi-Fi passwords. Your Mac uses a system called Keychain to securely store passwords, including Wi-Fi network passwords. The Keychain is a password management system that allows you to save passwords for various applications, websites, and networks, making it convenient to log in without having to remember each password. However, when you want your Mac to forget a Wi-Fi password, you’ll need to access and modify the Keychain.
Accessing Keychain on Mac
To access the Keychain on your Mac, follow these steps:
– Open the Applications folder.
– Go to the Utilities folder.
– Find and open Keychain Access.
– In the Keychain Access window, you’ll see a list of all the items you’ve saved, including passwords, certificates, and notes.
Navigating Through Keychain Access
Once you’re in the Keychain Access window, you can navigate through the different categories to find the Wi-Fi password you want to forget. The categories include:
– Keys: This category stores secure notes and keys.
– Certificates: Stores certificates used for secure connections.
– Passwords: This is where your Wi-Fi passwords are stored, among other types of passwords.
Steps to Forget a Wi-Fi Password on Mac
Forgetting a Wi-Fi password involves deleting the password from the Keychain. Here’s how you can do it:
Deleting a Wi-Fi Password from Keychain
To delete a Wi-Fi password, follow these steps:
– Open Keychain Access as described earlier.
– In the Keychain Access window, select the Passwords category.
– Look for the Wi-Fi network whose password you want to forget. It might be listed under the name of the network or as “Wi-Fi password” followed by the network name.
– Select the Wi-Fi network password you want to delete.
– Click on the Delete button at the top of the window or right-click (or control-click) on the selected item and choose Delete.
– You will be prompted to confirm the deletion. Enter your Mac’s administrator password to confirm.
Alternative Method: Forgetting Wi-Fi Network from Network Preferences
Alternatively, you can forget a Wi-Fi network directly from the Network preferences without having to delve into the Keychain. Here’s how:
– Click on the Apple menu and select System Preferences.
– Click on Network.
– Select Wi-Fi from the left-hand menu.
– Click on the Advanced button.
– In the Wi-Fi tab, you’ll see a list of preferred networks. Find the network you want your Mac to forget.

Forgetting a Wi-Fi password on your Mac can also be helpful when troubleshooting connectivity issues. If your Mac is having trouble connecting to a specific network, forgetting the password and then reconnecting can sometimes resolve the problem. Furthermore, if you have moved to a new location and no longer need to connect to certain networks, forgetting their passwords can help declutter your list of saved networks and make it easier to manage your connections. By making your Mac forget a Wi-Fi password, you can improve your device’s connectivity, security, and overall performance.
How do I make my Mac forget a Wi-Fi password using the Wi-Fi menu?
To make your Mac forget a Wi-Fi password using the Wi-Fi menu, click on the Wi-Fi icon in the menu bar and select “Open Network Preferences.” Then, click on “Advanced” and select the network you want to forget from the list of saved networks. Click the “-” button at the bottom of the list to remove the network, and then click “OK” to confirm. Alternatively, you can also use the “Forget” option directly from the Wi-Fi menu by holding down the “Option” key while clicking on the Wi-Fi icon, then selecting “Forget Network” from the dropdown menu.

Will making my Mac forget a Wi-Fi password affect my other devices?
No, making your Mac forget a Wi-Fi password will not affect your other devices. Each device stores its own list of saved Wi-Fi passwords, so forgetting a password on your Mac will only remove it from your Mac’s list of saved networks. Your other devices, such as your iPhone or iPad, will still be able to connect to the network using the saved password. However, if you are using a feature like iCloud Keychain to sync passwords across devices, forgetting a Wi-Fi password on your Mac may also remove it from your other devices that are synced with the same iCloud account.
If you want to remove a Wi-Fi password from all of your devices at once, you can use iCloud Keychain to delete the password from your iCloud account. To do this, go to System Preferences > Apple ID > Password & Security, and then click on “iCloud Keychain” to view your saved passwords. From there, you can select the Wi-Fi password you want to forget and click the “Delete” button to remove it from your iCloud account and all synced devices. This can help keep your passwords in sync across devices and make it easier to manage your network connections.
How do I make my Mac forget a Wi-Fi password using the Terminal app?
To make your Mac forget a Wi-Fi password using the Terminal app, you can use the command “sudo defaults delete /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist” to reset network settings and remove all saved Wi-Fi passwords. Alternatively, you can use the command “networksetup -removepreferredwirelessnetwork
Using the Terminal app to forget a Wi-Fi password can be useful if you are comfortable with using command-line interfaces and want more control over your network settings. However, keep in mind that using Terminal commands can be more complex and error-prone than using the Wi-Fi menu or System Preferences, so be sure to double-check your commands before running them. Additionally, resetting network settings using Terminal commands can also remove other network settings, such as custom DNS servers and proxy settings, so be sure to reconfigure these settings after resetting.
Will making my Mac forget a Wi-Fi password delete any other network settings?
Yes, making your Mac forget a Wi-Fi password using certain methods, such as resetting network settings, can also delete other network settings. For example, resetting network settings using the “Reset Network Settings” option in System Preferences or the Terminal app will remove all saved Wi-Fi passwords, as well as other network settings like custom DNS servers, proxy settings, and VPN configurations. However, if you use the Wi-Fi menu to forget a network, only the saved Wi-Fi password for that specific network will be removed, and other network settings will remain intact.
If you need to forget a Wi-Fi password but also want to preserve other network settings, it’s a good idea to use the Wi-Fi menu or System Preferences to remove the network, rather than resetting network settings. This will allow you to selectively remove the saved Wi-Fi password without affecting other network configurations. Alternatively, you can also use the Terminal app to remove a specific Wi-Fi network from your Mac’s list of saved networks, without resetting other network settings. By being mindful of the method you use to forget a Wi-Fi password, you can help preserve your other network settings and avoid unnecessary configuration changes.
Can I recover a forgotten Wi-Fi password on my Mac?
Yes, you can recover a forgotten Wi-Fi password on your Mac if you have previously saved it to your Keychain or iCloud Keychain. To do this, go to Applications > Utilities > Keychain Access, and then search for the name of the Wi-Fi network in the search bar. If the password is saved in your Keychain, you can select the entry and click on “Show Password” to view the password. Alternatively, if you are using iCloud Keychain, you can go to System Preferences > Apple ID > Password & Security, and then click on “iCloud Keychain” to view your saved passwords.
If you are unable to recover a forgotten Wi-Fi password using Keychain or iCloud Keychain, you may need to try other methods, such as checking your router’s documentation or contacting your network administrator. In some cases, you may also be able to recover a forgotten Wi-Fi password by using a third-party password recovery tool or by resetting your router to its default settings. However, keep in mind that these methods may not always work, and you may need to try a combination of approaches to recover your forgotten password. By using a combination of these methods, you can increase your chances of recovering a forgotten Wi-Fi password and regaining access to your network.
