Introduction

If your Mac keeps connecting to the wrong network, remembers an outdated password, or you simply want a clean slate, learning How to Forget Wifi Password Mac? is one of the most useful skills you can have. macOS stores every Wi-Fi network you have ever joined — along with its password — inside your system and your iCloud Keychain. Over time, this list can become cluttered, and stale entries can cause connection loops, “password incorrect” errors, or automatic connections to networks you no longer want to use.

This guide walks you through every reliable way to forget a Wi-Fi network and reset its password on macOS. Whether you are running the latest macOS Sonoma or an older release like macOS Monterey or Big Sur, you will find a method that works. We will cover the modern System Settings app, the legacy System Preferences panel, Keychain Access, and even a Terminal command for power users. By the end, you will know exactly how to remove a single network, clear all saved Wi-Fi passwords, and troubleshoot stubborn entries that refuse to disappear.

What Does “Forget a Wi-Fi Network” Mean on macOS?

When you join a Wi-Fi network, macOS saves two things: the network name (SSID) and the credentials used to authenticate. “Forgetting” a network tells macOS to delete that saved entry. The next time you are in range, your Mac will not connect automatically, and it will not reuse the stored password. You will be prompted to enter the password again as if it were a brand-new connection.

It is important to understand that forgetting a network is not the same as turning off Wi-Fi. Turning Wi-Fi off simply stops the radio from scanning. Forgetting removes the stored memory of that specific network. macOS keeps these memories in multiple places: the Wi-Fi preference list, the Keychain, and, if iCloud Keychain is enabled, your iCloud account. That is why a network sometimes “comes back” after you thought you deleted it.

When people search for How to Forget Wifi Password Mac?, they usually want one of three outcomes: remove a single network, reset a forgotten or wrong password, or wipe all saved Wi-Fi data. This article covers all three.

Why You Might Need to Forget a Wi-Fi Password on Mac

There are many everyday situations where forgetting a Wi-Fi network is the right move. Here are the most common ones:

  • Changed router password: If the Wi-Fi password on your router was updated but your Mac still tries the old one, you will get repeated “incorrect password” prompts.
  • Connection loops: macOS sometimes gets stuck trying to connect to a saved network that is no longer available, slowing down your login or boot time.
  • Privacy concerns: Old networks (hotels, cafés, airports) remain in your list and can reveal your travel history. Removing them protects your privacy.
  • Switching accounts: If you share a Mac, forgetting a network prevents automatic connections with another user’s saved credentials.
  • Troubleshooting slow Wi-Fi: A corrupted network entry can cause intermittent drops. Forgetting and rejoining often fixes it.
  • Selling or giving away your Mac: You should remove all saved Wi-Fi passwords before handing over the device.

In short, knowing How to Forget Wifi Password Mac? helps you maintain a clean, secure, and reliable connection.

Things to Know Before You Forget a Network

Before you delete anything, keep these points in mind:

  • If iCloud Keychain is turned on, the forgotten network may sync back from another Apple device (iPhone, iPad, or another Mac). To prevent this, turn off iCloud Keychain temporarily or forget the network on all devices.
  • Admin privileges are required to modify system-wide Wi-Fi settings in some cases, especially on managed or work Macs.
  • Forgetting a network does not disable Wi-Fi; it only removes that entry.
  • If you forget the only network your Mac knows, you will need to re-enter its password manually.
  • Some enterprise networks use 802.1X profiles that cannot be removed from the standard Wi-Fi list; those must be removed from System Settings > Privacy & Security or via a configuration profile.

How to Forget Wifi Password Mac: Method 1 — System Settings (macOS Ventura and Later)

On macOS Ventura, Sonoma, and Sequoia, Apple moved Wi-Fi management into the new System Settings app. This is the recommended method for most users.

Step-by-step instructions

  1. Click the Apple menu () in the top-left corner and choose System Settings.
  2. In the sidebar, click Wi-Fi.
  3. Make sure Wi-Fi is turned on.
  4. Scroll down to the section labeled Known Networks (or click Advanced on some builds, then Known Networks).
  5. Find the network you want to remove. You can use the search field to filter by name.
  6. Click the More (…) button next to the network name, or click the network and choose Forget This Network.
  7. Confirm by clicking Remove in the dialog box.
  8. The network disappears from the list immediately.

After this, macOS will no longer auto-connect to that SSID. If you are currently connected to it, your Mac will disconnect and you can join another network.

Pro tip for Ventura and later

If the network does not appear under Known Networks, it may be stored only in Keychain. Jump to the Keychain Access method below. Also note that on some macOS builds, the “Forget This Network” option appears only when you click the info (i) icon next to the network name.

Method 2 — System Preferences (macOS Monterey and Earlier)

If you are running macOS Monterey, Big Sur, Catalina, or older, the path is slightly different because Apple used System Preferences instead of System Settings.

Step-by-step instructions

  1. Click the Apple menu and select System Preferences.
  2. Click Network.
  3. Select Wi-Fi in the left sidebar.
  4. Click the Advanced… button in the bottom-right corner.
  5. In the Wi-Fi tab, you will see a list of Preferred Networks.
  6. Select the network you want to forget.
  7. Click the minus (–) button below the list.
  8. Click OK, then click Apply to save changes.

This removes the network from your preferred list and deletes its password from the local Wi-Fi store. If the password persists in Keychain, follow Method 3.

Method 3 — Using Keychain Access

Keychain Access is the most thorough way to remove a Wi-Fi password because it targets the actual credential store. Even after forgetting a network in System Settings, the password may linger in Keychain, which is why some users report that the network “remembers” them. This method is essential if you want a true reset.

Step-by-step instructions

  1. Open Spotlight (Command + Space) and type Keychain Access, then press Enter.
  2. In the left sidebar, under Keychains, select login (or Local Items).
  3. Under Category, select Passwords.
  4. Use the search box in the top-right to type the name of your Wi-Fi network (SSID).
  5. Look for an entry whose Kind is AirPort network password (on older macOS) or Wi-Fi network password.
  6. Select the entry, right-click (or Control-click), and choose Delete.
  7. Confirm the deletion when prompted.
  8. If prompted for your Mac user password, enter it.

If iCloud Keychain is enabled, the deletion may sync across your Apple devices. If you want to keep the password on your iPhone but remove it from the Mac, turn off iCloud Keychain first under System Settings > Apple ID > iCloud.

Caution

Deleting the wrong Keychain item can break other saved logins. Always double-check the name and the “Kind” field before deleting. If unsure, you can view the item’s details (double-click) to confirm the account name matches your SSID.

Method 4 — Terminal Command to Forget a Network

For advanced users and IT administrators, macOS provides a command-line tool called networksetup. This is useful for scripting, remote management, or when the GUI fails.

Step-by-step instructions

  1. Open Terminal from Applications > Utilities (or via Spotlight).
  2. First, list your Wi-Fi hardware port name (usually Wi-Fi or en0): 
    networksetup -listallhardwareports
  3. List all preferred (saved) networks: 
    networksetup -listpreferredwirelessnetworks "Wi-Fi"
  4. Forget a specific network by exact SSID name: 
    sudo networksetup -removepreferredwirelessnetwork "Wi-Fi" "YourNetworkName"
  5. Enter your administrator password when prompted.
  6. Confirm the network is gone by re-running the list command.

Replace "Wi-Fi" with your actual interface name if different, and replace "YourNetworkName" with the exact SSID, including spaces and capitalization. This command removes the entry from the preferred networks list. To also delete the password from Keychain, combine this with Method 3.

Resetting the entire preferred list via Terminal

If you want to clear every saved network at once, you can loop through them, but there is no single “forget all” flag. A common approach is:

networksetup -listpreferredwirelessnetworks "Wi-Fi" | tail -n +2 | while read net; do sudo networksetup -removepreferredwirelessnetwork "Wi-Fi" "$net"; done

Use this carefully — it removes all saved Wi-Fi networks from your Mac.

Comparison of All Methods

Here is a quick side-by-side comparison to help you choose the best approach for your situation.

Method Best For Removes Password Too? Requires Admin? macOS Version
System Settings Everyday users on modern macOS Usually yes No Ventura and later
System Preferences Users on older macOS Yes No Monterey and earlier
Keychain Access Stubborn or lingering passwords Yes (direct) Sometimes All versions
Terminal (networksetup) Power users, scripting, IT No (list only) Yes (sudo) All versions

For a complete reset, combining Method 1 (or 2) with Method 3 gives the cleanest result. That combination is the gold standard when you want to know How to Forget Wifi Password Mac? thoroughly.

How to Reset Wi-Fi Settings on Mac Completely

Sometimes forgetting one network is not enough. If your Wi-Fi is misbehaving across the board, you can reset all network settings. macOS does not have a single “reset network” button like iOS, but you can achieve the same result manually.

Full reset procedure

  1. Forget every saved network using Method 1 or Method 2 (or the Terminal loop above).
  2. Open Keychain Access and delete all entries with Kind AirPort network password or Wi-Fi network password.
  3. Turn off Wi-Fi from the menu bar or System Settings.
  4. Open Terminal and run the following to remove the Wi-Fi configuration plist (optional, advanced): 
    sudo rm /Library/Preferences/SystemConfiguration/com.apple.wifi.message-tracer.plist
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
  5. Restart your Mac.
  6. Re-enable Wi-Fi and rejoin your networks, entering passwords fresh.

Warning: Deleting system preference plists affects all network interfaces, not just Wi-Fi. Only do this if you are comfortable reconfiguring your network settings afterward. Back up your Mac first with Time Machine.

Forgetting Wi-Fi on Different macOS Versions

Apple has changed the UI several times, so the exact clicks depend on your version. Here is a quick reference:

  • macOS Sequoia / Sonoma / Ventura: System Settings > Wi-Fi > Known Networks > Forget This Network.
  • macOS Monterey / Big Sur: System Preferences > Network > Wi-Fi > Advanced > Preferred Networks > minus button.
  • macOS Catalina / Mojave: Same as Monterey, but the “Advanced” button may be labeled differently; look for the gear icon.
  • macOS High Sierra and older: System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab.

Regardless of version, Keychain Access and Terminal methods remain consistent across all macOS releases, which is why they are reliable fallbacks.

Troubleshooting Common Problems

Even after following the steps, you may run into issues. Here are the most common and how to fix them.

The network keeps coming back

This is almost always iCloud Keychain syncing. Turn off iCloud Keychain on your Mac, forget the network, then turn it back on. Alternatively, forget the network on every Apple device signed into the same Apple ID.

“Forget This Network” is greyed out

Your Mac may be managed by an MDM (Mobile Device Management) profile, or you lack admin rights. Check System Settings > General > Device Management. Contact your IT administrator if a profile is installed.

The network is not in the list

It may be stored only in Keychain. Use Method 3. Also check that you are looking under the correct Keychain (login vs. Local Items).

Mac still says “incorrect password” after forgetting

The password may be cached in a different Keychain item or in an 802.1X profile. Delete all related entries in Keychain Access and restart. If using enterprise Wi-Fi, remove the configuration profile.

Terminal command says network not found

The SSID is case-sensitive and must match exactly. Copy the name from the list command. Also ensure the interface name is correct (run networksetup -listallhardwareports).

Tips and Best Practices

  • Forget networks you no longer use at least once a quarter to keep your list clean.
  • Use Keychain Access when you want to be certain a password is gone — the GUI alone sometimes leaves traces.
  • Disable auto-join for networks you want to keep saved but not connect to automatically: in System Settings, click the info (i) icon next to a network and toggle off Auto-Join.
  • Back up Keychain before mass deletions: in Keychain Access, choose File > Export Items.
  • On shared Macs, create separate user accounts so Wi-Fi passwords stay isolated per user.
  • After a reset, re-add networks one at a time and test each connection before adding the next.
  • Keep macOS updated — Apple occasionally fixes Wi-Fi bugs that cause stale entries.

Frequently Asked Questions

Does forgetting a Wi-Fi network delete the password everywhere?

Not always. It removes it from your Mac’s preferred networks list. If iCloud Keychain is on, the password may still exist on your other Apple devices and could sync back. Delete it from Keychain Access for a thorough removal.

Can I forget a Wi-Fi network without knowing the password?

Yes. You do not need the current password to forget a network. You only need admin access to your Mac (and sometimes not even that, depending on the method).

Will forgetting Wi-Fi disconnect me right now?

If you are currently connected to that network, yes — macOS will disconnect you immediately after you forget it.

How do I see all saved Wi-Fi passwords on my Mac?

Open Keychain Access, select the login keychain, search for your SSID, and double-click the entry. Check “Show password” and authenticate with your Mac password to reveal it.

Why does my Mac keep reconnecting to a forgotten network?

iCloud Keychain is likely re-syncing it. Turn off iCloud Keychain temporarily, forget it again, and check your iPhone/iPad for the same entry.

Is there a way to forget all Wi-Fi networks at once?

There is no single button, but you can use the Terminal loop command shown earlier, or manually delete each entry in Keychain Access. A full network reset (deleting preference plists) is the nuclear option.

Does this work on macOS in Safe Mode?

Yes, but Wi-Fi functionality may be limited. It is better to perform these steps in normal mode.

What is the difference between “Forget This Network” and turning off Auto-Join?

Forgetting deletes the saved password and SSID entirely. Turning off Auto-Join keeps the password saved but stops automatic connections — you can still connect manually with one click.

Conclusion

Knowing How to Forget Wifi Password Mac? gives you full control over which networks your computer remembers and trusts. For most users, the modern System Settings path (or System Preferences on older macOS) is the quickest fix. When a password lingers or a network keeps reappearing, Keychain Access is the most reliable tool, and Terminal commands give power users and administrators the precision they need. Combine the GUI method with Keychain cleanup for a truly clean slate, and remember to manage iCloud Keychain if your entries keep syncing back. With these techniques, you can resolve connection issues, protect your privacy, and keep your Mac’s Wi-Fi list tidy for years to come.
