How to Change Your Wi-Fi Password: A Simple Step-by-Step Guide

Changing your Wi-Fi password takes about five minutes, and you only need a phone or computer that is already connected to your network. You log in to your router’s settings, type in a new password, save it, and then reconnect your devices with the new password. That is the whole job. This guide walks you through it step by step, including what to do if you rent your router from your internet provider.

Quick answer: how to change your Wi-Fi password

1. Connect a phone or computer to your Wi-Fi network (or plug a computer into the router with an Ethernet cable).
2. Open a browser and type your router’s address, usually 192.168.1.1 or 192.168.0.1. You will find the exact address on the sticker on the bottom or back of your router.
3. Log in with the router’s admin username and password, also printed on that sticker.
4. Open Wireless, Wi-Fi, or Wireless Settings.
5. Find the Wi-Fi Password, Network Key, or Passphrase box, type your new password, and save.
6. Reconnect every device with the new password.

If you rent a gateway from your internet provider, you can usually skip the browser steps and change the password in the provider’s app instead. That method is covered below.

Before you start: two different passwords

This trips up a lot of people, so it is worth getting straight first. Your router has two passwords, and they do different jobs:

• Wi-Fi password: the password your phone, laptop, and TV type in to join your wireless network. This is the one you are changing today.
• Admin password: the password that opens your router’s settings page. You need it to get in, but your devices never use it.

If you have never changed either one, both are printed on the sticker on your router. Take a photo of that sticker before you start. It saves a lot of hunting around later.

Method 1: Change it in your browser (works on any router you own)

Step 1: Find your router’s address

On most home routers the address is 192.168.1.1 or 192.168.0.1. Some use 10.0.0.1. If none of those work, check the sticker on your router for an address labelled “gateway,” “login,” or “router IP.” You can also find it on a connected device: on Windows, look under Wi-Fi settings for “Default gateway”; on a Mac, look in Wi-Fi settings under Details for “Router”; on an iPhone or Android phone, look in the Wi-Fi network details for “Router” or “Gateway.”

Step 2: Log in to the router settings

Type the address into your browser’s address bar and press Enter. A login page will appear. Enter the admin username and password from the router sticker. On older routers this is often “admin” for both, but newer routers come with a unique password printed on the label, so check there first.

If your browser warns you the connection is not private, that is normal for a router’s local page. Just make sure the address in the bar is exactly your router’s address, then continue to the login page.

Step 3: Open the wireless settings

Once you are in, look for a menu called Wireless, Wi-Fi, Wireless Settings, or WLAN. The exact name changes with the brand, but it is always in the main menu, not buried in advanced settings. On TP-Link routers it is usually under Advanced, then Wireless, then Wireless Settings. On NETGEAR it is under Wireless. On ASUS it is under Wireless, then General.

Step 4: Type in the new password

Look for the box labelled Wi-Fi Password, Password, Network Key, Passphrase, or WPA Pre-Shared Key. They all mean the same thing. Delete the old password and type in the new one.

While you are here, check the security setting next to it. It should say WPA2 or WPA3. If it says WEP or WPA only, your router is very old. Change the password anyway, but think about replacing the router soon, because those old settings are easy to crack.

If your router shows separate passwords for the 2.4 GHz and 5 GHz networks, you can set both to the same new password unless you deliberately run them as two different networks. Most modern routers use one network name for both, so one password covers everything.

Step 5: Save, then reconnect everything

Click Save or Apply. The router will apply the change within a few seconds, and every device on your Wi-Fi will drop off at once. That is supposed to happen. It does not mean something went wrong. Now go through your devices one by one and reconnect them with the new password. The reconnect checklist below covers the ones people usually forget.

Method 2: Change it in your internet provider’s app

If you rent your router or gateway from your provider, the browser method may not work, because the provider locks down the settings page. In that case, use the provider’s app. It is usually faster anyway:

• Xfinity: open the Xfinity app, go to Wi-Fi, pick your network, and tap to edit the password.
• Verizon Fios: open My Verizon, go to Internet, pick your network, and edit the password.
• Cox: open the Cox app and edit the Wi-Fi password under your Panoramic Wifi network settings.
• Other providers: open your provider’s app and look for Wi-Fi, My Network, or Internet settings. The password option is almost always there.

Changes made in a provider app sync to the gateway on their own, so you do not need to touch the browser settings as well. Just reconnect your devices afterwards, the same as with Method 1.

What makes a good Wi-Fi password

You do not need a random jumble of symbols that nobody can type on a TV remote. A long passphrase works better and is easier to live with. Aim for at least 15 characters, for example four ordinary words strung together. That is hard for a stranger to guess and easy for you to type.

A few rules that actually matter:

• Make it different from your router’s admin password.
• Do not reuse a password you use for email or banking.
• Do not use your address, your name, or your phone number.
• Change it when there is a reason: you shared it with someone who moved out, a device was lost or sold, you spot a device you do not recognise, or it is still the factory default. You do not need to change it on a calendar schedule just for the sake of it.

Reconnecting your devices (the part people forget)

Every device that knew the old password will need the new one. On most phones and laptops, open the Wi-Fi list, tap your network, and if it keeps failing, choose Forget first, then join again and type the new password carefully. Watch out for caps lock and extra spaces at the end.

Do not forget these:

• Smart TVs and streaming sticks
• Printers
• Smart speakers, cameras, doorbells, and other smart-home devices
• Game consoles
• Tablets and e-readers
• Any laptop that only connects occasionally

Smart-home devices usually ask for the new password the next time you open their app. If one refuses to connect, check that you are joining the right band: older smart devices often only work on 2.4 GHz, not 5 GHz.

If your internet still feels slow after the password change, the password was probably not the problem. A new password changes who can join your network, not your line speed. Our step-by-step guide to fixing slow Wi-Fi at home covers the usual real causes, from router placement to interference.

Troubleshooting: when something goes wrong

I cannot reach the router’s settings page

First, make sure the device you are using is actually connected to your router’s network, not a mobile hotspot or a neighbour’s Wi-Fi. Turn off any VPN, then try the address from the router sticker again, typed exactly. If you are on Wi-Fi and it still will not load, try a computer plugged into the router with an Ethernet cable.

The admin password does not work

Try the username and password printed on the router sticker again, and check your password manager for a saved entry. If someone changed the admin password and nobody remembers it, the only way back in is a factory reset: press and hold the small reset button on the back of the router with a pin for about 10 seconds. That restores the sticker defaults, but it also wipes your other settings, so photograph your current settings first if you can still get online another way.

Devices will not reconnect with the new password

Forget the network on the device and join it fresh, rather than just retrying. Double-check for caps lock, autocorrect, and trailing spaces. If only one device fails while the rest work, the problem is on that device, not the router: restart it, forget the network, and try again.

I forgot the new password right after changing it

Log back into the router settings and look at the Wi-Fi password box. Most routers show it there. Your provider’s app shows it too. If you cannot get into either, a factory reset takes you back to the sticker defaults, and then you can set a fresh password.

Frequently asked questions

Will changing my Wi-Fi password kick everyone off?

Yes, and that is the point. Every device will disconnect until it is given the new password. Anyone using your network without your permission will be locked out too.

Do I need to change the Wi-Fi name as well?

No. Changing the password does not change your network name, and you do not need to change the name for the password change to work. Only change the name if you want to, and know that it will also force every device to reconnect.

Can I change my Wi-Fi password from my phone?

Yes. Open the router’s address in your phone’s browser, or use your router brand’s app or your provider’s app. You do not need a computer for this.

How often should I change my Wi-Fi password?

When there is a reason, not on a fixed schedule. A long, unique password on WPA2 or WPA3 does far more for your security than changing a weak password every few months.
