How can you change your Wi-Fi password without getting locked out?

Someone has asked for your Wi-Fi password, and you realise several people already have it. You can change the password without buying a new router or calling a technician. The catch is that every phone, television and laptop using the old password will need to connect again.

To change your Wi-Fi password, connect to your router, open its management page or official app, find the wireless security settings, enter a new password and save it. The exact menu names depend on the router. Keep your new password somewhere safe before you press Save, because your phone may disconnect immediately.

This guide covers home routers and pocket Wi-Fi devices. If your internet provider controls the router, its app or support team may be needed for some settings.

Before you change anything

Choose a time when nobody is in the middle of a video call or an important upload. A password change can disconnect smart TVs, security cameras and other devices as well as phones and laptops. If you work from home, give people using the connection a little notice.

Find the router’s model name and label. The label may show the default Wi-Fi name, an address for the management page and initial login details. It does not necessarily show the current password if someone changed it after installation.

You need two different things:

• The Wi-Fi password connects a device to the network.
• The router admin password opens the router’s settings.

They are not always the same. Changing the Wi-Fi password does not automatically change the admin password, and the password for your internet provider’s app may also be separate.

If this is a shared office, school or rented connection that you do not manage, ask the person in charge before making changes. Changing a shared password can interrupt everyone else’s access.

Step 1: Connect to the router

On your phone or laptop, connect to the Wi-Fi network you want to manage. If you know the current password, use it as usual. A laptop connected to the router with an Ethernet cable can also be useful because it may stay connected when the wireless password changes.

If you no longer know the Wi-Fi password, check whether a phone or computer you own is already connected. You can use that device to open the settings. Some devices let you view or share a saved Wi-Fi password after you unlock them. The exact option depends on the operating system.

Do not factory-reset the router simply because one device forgot the password. Resetting can remove your provider’s configuration and leave you without internet until the connection is set up again.

Step 2: Open the router settings

Look at the router label or its manual for the management address. Enter that address into the browser’s address bar, not a search box. Some manufacturers also offer an official management app. Download it from the device maker’s official website or your phone’s app store, and check the publisher name before installing.

Addresses such as `192.168.1.1` or `192.168.0.1` are common, but neither is guaranteed to work for your device. If the label does not help, check the router or gateway address in the network details on a device connected to that Wi-Fi. On many Android phones, you can open Wi-Fi settings, tap the connected network and look under its details. The labels vary by phone.

A provider-supplied router may use the provider’s app or a different local address. Use its model-specific instructions rather than guessing repeatedly.

Step 3: Sign in as the administrator

Enter the router’s admin credentials when prompted. If you have changed them before, use the current details rather than the default credentials printed on the label. The router’s admin login is not necessarily your email address or your Wi-Fi password.

If the login fails, check for typing mistakes and confirm you are on the correct router’s local page. If someone else installed the connection, ask them for the admin details. For a provider-managed router, contact the provider through its official support channel.

Never give a stranger your admin password or a one-time code because they claim they can fix the network remotely. A legitimate support agent should not need your banking PIN to change a Wi-Fi password.

Step 4: Find the Wi-Fi security settings

Look for a menu called Wireless, Wi-Fi, Wireless Settings or Wireless Security. Some routers separate the network name from the password under an advanced menu. On a mobile Wi-Fi device, the layout can be different again.

You may see separate settings for the 2.4 GHz and 5 GHz bands, or a single setting that applies to both. If the device uses separate network names and passwords, make a note of which one you are changing. Don’t disable a band or alter unfamiliar internet settings while looking for the password.

Check the security mode too. Use WPA3 where your router and devices support it, or WPA2-AES if WPA3 is not practical. Some older devices may not connect to WPA3-only networks. Avoid changing several settings at once, so it is easier to identify the cause if a device cannot reconnect.

Step 5: Enter and save a new password

Choose a long, unique password that you have not used for email, banking or another Wi-Fi network. A password manager can generate one and store it for you. If you prefer a passphrase, use several unrelated words and follow the router’s length and character rules. Avoid your phone number, house address, surname or the network name.

Type the password carefully, note it somewhere private, then tap Save or Apply. Your router may briefly restart its wireless connection. If you used Wi-Fi to open the settings, your phone might disconnect before you see a confirmation. That can be normal, but wait for the router to finish before trying again.

Manufacturer menus differ. TP-Link’s wireless settings guide gives an example for its supported routers; use your own manufacturer’s guide for model-specific steps.

Step 6: Reconnect your devices

On each phone or laptop, select the Wi-Fi network and enter the new password. If a device keeps trying the old one, open its Wi-Fi settings, forget the saved network and connect again. Make sure you have the new password before forgetting it.

Remember devices that are easy to overlook, such as a printer, streaming box, security camera or smart speaker. Some need to be reconnected through the device maker’s app. If one cannot connect, check whether it supports your chosen security mode and Wi-Fi band before changing the router again.

Share the new password only with people who need access. For visitors, use a guest network if your router supports one and you know how it separates guest access. Our guide to securing your home Wi-Fi covers other settings worth reviewing.

What if you are locked out?

First check whether a device is still connected by cable or whether the router’s official app can reach it. If you forgot the admin password, contact the installer or your provider. Some routers can only recover access through a factory reset, but that should be a last resort: it can erase the wireless name, password and internet configuration.

Before resetting, get the setup details and confirm how to restore the provider’s connection. A small reset button is not the same as an ordinary power button. If you are not sure which one to use, ask the provider rather than holding it down.

Once the new password works, check a few devices and keep the admin details secure. You have changed who can join your Wi-Fi without needing to expose the rest of your router settings.
