The fastest way to change your password depends on your router type

Most home routers let you change the password through a web browser or a mobile app. You log into your router's admin panel — usually by typing an address like 192.168.1.1 or 192.168.0.1 into your browser's address bar — then find the wireless settings or WiFi password section. The exact steps vary by manufacturer: Netgear, TP-Link, Linksys, and Asus all arrange their menus differently, but they all have a field where you can type a new password and save it.

If you do not know your router's IP address, you can find it by opening Command Prompt (Windows) or Terminal (Mac) and typing ipconfig (Windows) or ifconfig (Mac), then looking for the "Default Gateway" line. Alternatively, most routers have a sticker on the back with the address printed on it. Your router's manual or the manufacturer's website will tell you the default username and password if you have never changed them before.

Some newer routers — particularly mesh systems like Eero, Google Nest, or Ubiquiti — only let you change the password through their mobile app rather than a web browser. read the app, sign into your account, find the WiFi settings section, and change the password there. The app will push the change to all your devices automatically.

Key Takeaways

  • You change your WiFi password by logging into your router's admin panel using its IP address (usually 192.168.1.1) or through the router's mobile app.
  • Your new password should be at least 12 characters long and include uppercase letters, numbers, and symbols to resist guessing attacks.
  • After you change the password, all your connected devices will disconnect and you will need to reconnect them using the new password.
  • Change your password when ready if you suspect someone has accessed your network, and consider changing it every 90 days if you live in a shared building or have frequent guests.

What password length and type actually protect you

A strong WiFi password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols. Something like BlueSky#2024Rain or Coffee$Morning7@Home is far harder to crack than a straightforward word or a short string of numbers. The longer and more varied your password, the longer it would take an attacker to guess it through brute force — trying thousands of combinations per second.

Avoid passwords that contain your name, your address, your birth year, or your WiFi network name. These are the first things an attacker will try because they are straightforward to find from public information or by looking at your router. Do not reuse a password you use for email, banking, or social media, because if one of those accounts is breached, your WiFi becomes vulnerable too.

Write your new password down in a physical notebook or in a password manager like Bitwarden or 1Password, not in a text file on your computer. A text file can be stolen if your computer is compromised; a password manager encrypts the password so that only you can read it.

What happens to your devices when you change the password

When you save a new password in your router, every device currently connected to your WiFi will lose the connection within a few seconds. Your phone, laptop, smart TV, and any other connected devices will show that the network is no longer available. You will then need to reconnect each device by selecting your network name, entering the new password, and waiting for the connection to establish.

This process usually takes less than a minute per device. Start with the devices you use most — your phone and laptop — then move to less critical devices like smart speakers or security cameras. If a device refuses to connect after you enter the correct password, restart the device and try again. Some older devices or smart home equipment may have trouble connecting to newer WiFi standards; if that happens, check your router's settings to see if you can enable an older standard like 802.11n alongside the newer one.

When to change your password right away

Change your password when ready if you notice unfamiliar devices connected to your network, if your internet speed suddenly drops without explanation, or if you see a device you do not recognize in your router's connected devices list. These are signs that someone may have guessed or obtained your password and is using your network.

You should also change your password if you have recently given it to a guest, contractor, or repair person and they no longer need access. Even if you trust them, their phone or laptop could be compromised, and an attacker could use that device to access your network. Change the password as soon as they leave.

If you live in an apartment building, a dorm, or any shared housing where neighbors are close by, change your password every 90 days. The closer people are to your router, the easier it is for them to attempt to crack your password. Frequent password changes make it harder for someone to maintain access over time.

How to find your router's admin password if you forgot it

If you have never changed your router's admin password — the password you use to log into the router itself, not your WiFi password — it is still the factory default. Check the sticker on the back of your router or the manual that came with it. Common defaults are admin/admin, admin/password, or a blank username with admin as the password.

If you changed the admin password and forgot it, you will need to reset your router to factory settings. This erases all your custom settings, including your WiFi password, and returns the router to its original state. Most routers have a small reset button on the back that you hold down for 10 to 15 seconds while the router is powered on. After the reset, you can log in with the factory default credentials and set up your WiFi password again from scratch.

Resetting your router is disruptive because you will lose any custom settings you made — port forwarding, parental controls, or network names — so only do this if you truly cannot remember the admin password. If you set a strong admin password when you first configured your router, write it down in your password manager alongside your WiFi password so you do not lose it.

The difference between your WiFi password and your admin password

Your WiFi password is what you give to guests or use to connect your phone and laptop to the internet. Your admin password is what you use to log into the router itself to change settings. They are separate, and you should change both.

Many people never change their admin password because they assume only they will access the router. But if someone gains access to your WiFi network, they can often reach your router's admin panel from inside the network and change your WiFi password to lock you out. Changing your admin password to something strong and unique prevents this. Use a password manager to store it so you do not forget it.

Frequently Asked Questions

Do I have to change my WiFi password if I change my internet provider?

No, but you will get a new router from your new provider. That new router will have a default WiFi password printed on a sticker. You should change it when ready to something strong and unique, following the same steps as above. Your old router will no longer work once your old provider disconnects the service.

What if I change my password and my smart home devices stop working?

Smart home devices like cameras, doorbells, and thermostats need to be reconnected to your new WiFi password. Open each device's app, find the WiFi settings, and enter your new password. Some devices have a reset button you hold down until the device enters pairing mode, then you select your network and enter the password through the app. Check the device's manual if you are unsure.

Can someone change my WiFi password if they are connected to my network?

Yes, if they know or guess your router's admin password. This is why changing your admin password is as important as changing your WiFi password. If you suspect someone has accessed your router, change both passwords when ready and check your connected devices list to see if anything unfamiliar is there.

Is it safe to use a password generator to create my WiFi password?

Yes. Password generators like those built into Bitwarden, 1Password, or even your browser create random, strong passwords that are much harder to crack than anything you would type by hand. The only downside is that a generated password like 7kL#mP9$xQ2@wR is harder to remember, so store it in a password manager rather than trying to memorize it.
