Introduction

If you are asking, “How Do You Change Wifi Password on Mac?” the answer depends on what you actually want to change. In many cases, people want to change the password for the Wi-Fi network itself, which means updating the settings on the router. In other cases, they want to update a saved Wi-Fi password on the Mac because the network password was changed somewhere else. Both situations are common, and macOS gives you several ways to handle them.

This guide explains the difference, shows step-by-step methods for changing a router Wi-Fi password from a Mac, and shows how to update or remove saved Wi-Fi credentials in macOS. It also covers troubleshooting, security tips, and best practices so your network remains stable and protected.

What Does “Change Wi-Fi Password on Mac” Mean?

The phrase “How Do You Change Wifi Password on Mac?” can refer to two different tasks. The first task is changing the password that devices use to join your Wi-Fi network. That password is stored and controlled by your router, not by your Mac. The second task is changing or deleting a Wi-Fi password that macOS has saved in its Keychain. That saved password helps your Mac reconnect automatically, but changing it on the Mac does not change the router’s password.

If your goal is to make everyone reconnect with a new password, you must change the router’s Wi-Fi password. If your goal is simply to fix a connection error after someone else changed the router password, you usually need to update or remove the saved password on your Mac.

Changing the Router Password vs. Changing the Saved Mac Password

A router password change affects every phone, tablet, computer, smart TV, and smart home device connected to that network. A saved Mac password change affects only that Mac. This distinction matters because many users try to change the password in macOS settings and then wonder why other devices still use the old password.

For example, if you change the password in Keychain Access, your Mac may stop using the old credential, but your router continues broadcasting the same network name with the same password. To change the actual Wi-Fi password, you must log in to the router and update its wireless security settings.

Before You Start: Important Preparation

Before changing any Wi-Fi password, make sure you have a reliable way to access your network afterward. Password changes can disconnect devices, and if you make a mistake, you may need to reset the router. Preparation reduces the risk of losing access.

What You Need

  • Your Mac connected to the Wi-Fi network, preferably by Ethernet if possible.
  • The router’s admin username and password, often printed on a label.
  • The router’s IP address, commonly something like 192.168.1.1 or 192.168.0.1.
  • A strong replacement password that you can store safely.
  • Access to other important devices so you can reconnect them later.

Safety and Backup Tips

  • Write down the current Wi-Fi password before changing it.
  • Keep the router label or manual nearby.
  • Do not change the network name unless necessary.
  • Use a password manager to store the new password.
  • Avoid making changes when you urgently need internet access.

If your Mac is the only device connected and you are using Wi-Fi, changing the router password may disconnect you before you finish. Using an Ethernet cable or a temporary mobile hotspot can prevent that problem.

Method 1: Change the Wi-Fi Password on Your Router Using a Mac

This is the method to use when you want to change the actual password for your Wi-Fi network. The exact menu names vary by router brand, but the general process is similar.

Step-by-Step Using a Web Browser

  1. Connect your Mac to the router. Ethernet is best, but Wi-Fi also works if you know you may be disconnected.
  2. Open a web browser such as Safari, Chrome, or Firefox.
  3. Type the router’s IP address into the address bar and press Return.
  4. Log in with the router admin username and password.
  5. Look for a section named Wireless, Wi-Fi, WLAN, or Network Settings.
  6. Find the field for Wi-Fi Password, Passphrase, Pre-Shared Key, or Security Key.
  7. Enter a new strong password.
  8. Choose a modern security type such as WPA2 or WPA3 if available.
  9. Save or apply the changes.
  10. Wait for the router to restart or update its wireless settings.
  11. Reconnect your Mac and other devices using the new password.

If you are not sure of the router IP address, you can find it in macOS. Open System Settings, go to Wi-Fi, click the details button next to your connected network, and look for the router address. On older macOS versions, you can use System Preferences and then Network.

Using a Manufacturer App

Many modern routers include companion apps. Brands such as Eero, TP-Link, Netgear, ASUS, Linksys, and Google Nest may let you change the Wi-Fi password from an app on your Mac if an app is available, or from an iPhone or iPad. The general process is to open the app, select your network, go to settings, choose the Wi-Fi password option, enter a new password, and save.

Manufacturer apps can be easier than browser dashboards, especially for mesh systems. However, the exact path depends on the app version. Always look for terms such as Network Settings, Wi-Fi Settings, Security, or Password.

Method 2: Change a Saved Wi-Fi Password in macOS Keychain

If the router password has already changed and your Mac keeps trying to use the old one, you may need to update or delete the saved credential. macOS stores many passwords in Keychain Access. You can edit a Wi-Fi password there, but this only changes what your Mac remembers. It does not change the router.

Using Keychain Access

  1. Open Finder.
  2. Go to Applications, then Utilities.
  3. Open Keychain Access.
  4. In the search box, type the name of your Wi-Fi network.
  5. Look for an entry with kind AirPort network password or a similar wireless password type.
  6. Double-click the entry.
  7. Check Show password.
  8. Enter your Mac administrator password or use Touch ID when prompted.
  9. View the current saved password.
  10. Replace it with the new password if needed.
  11. Click Save Changes.

If you cannot edit the entry, you can delete it. After deletion, macOS will ask for the Wi-Fi password the next time you connect. This is often the simplest fix when the saved password is wrong or corrupted.

Important Notes About Keychain

  • Do not delete entries unless you know what they are.
  • Keychain Access contains many saved credentials, not just Wi-Fi passwords.
  • If iCloud Keychain is enabled, changes may sync to other Apple devices.
  • If the entry does not appear, try searching for the exact network name.

Updating the saved password can help when your Mac repeatedly fails to connect after a router password change. However, if the router password itself is different, you must still use the correct current password.

Method 3: Use Terminal to Remove a Saved Network Password

Advanced users can use Terminal to remove a saved Wi-Fi password. This is useful when Keychain Access is difficult to navigate or when you want a direct command-line approach. Be careful, because Terminal commands can affect system settings.

One common approach is to use the security command to delete a generic password item associated with the network. The exact command depends on the macOS version and how the credential is stored. A typical example looks like this:

security delete-generic-password -a "YourNetworkName" -s "AirPort" /Library/Keychains/System.keychain

Because command syntax and Keychain locations can vary, use this method only if you understand Terminal. After removing the saved password, disconnect and reconnect to the Wi-Fi network, then enter the correct password when prompted.

If you are unsure, use Keychain Access or the “Forget This Network” option instead. Those methods are safer for most users.

Method 4: Forget the Network and Reconnect

For many people, the easiest way to fix a wrong saved Wi-Fi password is to make macOS forget the network. This removes the saved credential and forces a fresh connection.

  1. Open System Settings on your Mac.
  2. Select Wi-Fi.
  3. Click the details or info button next to the network name.
  4. Choose Forget This Network.
  5. Confirm the action.
  6. Reconnect to the network from the Wi-Fi menu.
  7. Enter the current Wi-Fi password when prompted.
  8. Choose whether to remember the password.

This method is especially helpful when a network password has changed and macOS keeps attempting the old one. It does not change the router password, but it gives your Mac a clean start.

Method 5: Change a Personal Hotspot Password

If you are using an iPhone or iPad as a personal hotspot and connecting your Mac to it, the password is controlled by the mobile device, not by macOS. To change it, use the iPhone or iPad.

  1. Open Settings on the iPhone or iPad.
  2. Tap Personal Hotspot.
  3. Tap Wi-Fi Password.
  4. Enter a new password.
  5. Tap Done.

Then on your Mac, forget the hotspot network if it still uses the old password, and reconnect with the new one. Personal hotspot passwords should also be strong because they protect your mobile data connection.

Comparison of Common Methods

The best method depends on whether you are changing the network password or fixing a saved password on your Mac. The table below compares the most common approaches.

Method What It Changes Difficulty Best For
Router web dashboard Actual Wi-Fi network password Medium Changing password for all devices
Manufacturer app Actual Wi-Fi network password Easy Modern routers and mesh systems
Keychain Access Saved Mac password only Medium Correcting stored credentials
Forget network Saved Mac password only Easy Quickly fixing connection loops
Terminal command Saved Mac password only Advanced Power users and troubleshooting

Troubleshooting Common Issues

Even when you follow the correct steps, Wi-Fi password changes can cause connection problems. The issues below are common and usually easy to fix.

Mac Will Not Connect After Password Change

If your Mac refuses to connect after a password change, first confirm that you are entering the exact new password. Wi-Fi passwords are case-sensitive. Check for extra spaces, confusing characters such as uppercase O and zero, or lowercase L and number one. If the password is correct, forget the network and reconnect. Restarting the Mac can also clear temporary network cache issues.

Keychain Conflicts

Sometimes macOS tries to use an old saved password even after you type a new one. This can happen when multiple Keychain entries exist for the same network. Search Keychain Access for the network name and delete outdated entries. Then reconnect and save only the correct password.

Cannot Log In to the Router

If you cannot access the router dashboard, verify that you are connected to the router and using the correct IP address. Try common addresses such as 192.168.1.1, 192.168.0.1, or 10.0.0.1. If the admin password does not work, check the router label. If someone changed it and did not save it, you may need to reset the router to factory settings, which should be a last resort.

Other Devices Still Use the Old Password

After changing the router password, every device must use the new one. Phones and tablets usually prompt for the new password automatically. Smart TVs, printers, cameras, and smart home devices may need manual updates. Make a list of connected devices before changing the password so you do not forget any.

Best Practices for Wi-Fi Passwords

A good Wi-Fi password should be long, unique, and hard to guess. Avoid using personal information, simple words, or short passwords. A passphrase with multiple random words can be both strong and memorable. Many security experts recommend at least 12 to 16 characters.

  • Use a mix of uppercase letters, lowercase letters, numbers, and symbols.
  • Avoid reusing passwords from other accounts.
  • Do not use your name, address, phone number, or pet name.
  • Change the password if you suspect unauthorized access.
  • Store it in a password manager instead of writing it on a sticky note.

If your router supports WPA3, use it. If not, use WPA2. Avoid older security modes such as WEP or open networks because they are insecure.

Security Tips for Mac and Wi-Fi Networks

Changing your Wi-Fi password is only one part of network security. You should also keep macOS updated, enable the firewall, and review connected devices regularly. In macOS, you can enable the firewall in System Settings under Network or Security & Privacy, depending on your version.

Consider creating a separate guest network for visitors. This keeps your main devices isolated and reduces the chance that a guest device introduces security risks. If your router supports it, disable WPS, because it can weaken wireless security.

Review your router’s admin password as well. Many people change the Wi-Fi password but leave the router admin password as the default. That is a security risk. Change both passwords to strong, unique values.

Frequently Asked Questions

Can I change my Wi-Fi password directly from macOS settings?

No. macOS settings can help you forget or reconnect to a network, but they do not change the password stored on the router. To change the actual Wi-Fi password, you must use the router’s admin dashboard or app.

How Do You Change Wifi Password on Mac without knowing the router password?

You usually cannot change the router Wi-Fi password without the router admin credentials. If you do not know them, check the router label, manual, or your internet provider’s account. As a last resort, you may reset the router to factory settings, but that will erase custom settings.

Why does my Mac keep asking for the Wi-Fi password?

This often happens when the saved password is wrong, the Keychain entry is corrupted, or the router password changed. Forget the network, reconnect, and enter the current password. If the problem continues, check Keychain Access for duplicate entries.

Will changing the Wi-Fi password disconnect all devices?

Yes. Changing the router password disconnects all devices using the old password. Each device must reconnect with the new password. Your Mac may reconnect automatically if you update its saved credential first.

Is it safe to store my Wi-Fi password in Keychain?

Yes, Keychain is designed to store credentials securely. However, you should protect your Mac with a strong login password and enable FileVault if appropriate. If iCloud Keychain is enabled, the password may sync across your Apple devices.

What should I do if I forget my new Wi-Fi password?

Check your password manager, router label if unchanged, or another connected device. You can also log in to the router dashboard to view or reset the password. If all else fails, reset the router and set a new password.

Conclusion

When someone asks, “How Do You Change Wifi Password on Mac?” the most accurate answer is that it depends on whether they mean the router password or the saved Mac password. To change the actual network password, use your router’s web dashboard or manufacturer app from your Mac. To fix connection problems after a password change, use Keychain Access, Terminal, or the Forget This Network option.

By preparing ahead, using a strong password, and reconnecting devices carefully, you can change your Wi-Fi password without unnecessary downtime. A secure Wi-Fi network protects your data, your devices, and everyone who connects to your home or office internet.
