The fastest way: log into your router's admin panel

Your router has a built-in control panel you reach through a web browser on any device connected to your WiFi. Open a browser, type 192.168.1.1 or 192.168.0.1 into the address bar, and press Enter. You will be asked for a username and password — these are different from your WiFi password and are usually printed on a sticker on the router itself or in the manual that came with it.

Once you are logged in, look for a section called "Wireless," "WiFi," "Security," or "Network Settings." The exact name depends on your router brand. Find the field labeled "Password," "Passphrase," or "Pre-Shared Key" and replace the old password with a new one. Save or explore the changes. Your router will restart, and your new password takes effect when ready.

If you cannot find the admin panel using those IP addresses, check the sticker on your router or search online for "[your router model] default IP address." Different manufacturers sometimes use different addresses.

Key Takeaways

  • You reach your router's control panel by typing 192.168.1.1 or 192.168.0.1 into a web browser on a connected device.
  • The username and password for the admin panel are printed on a sticker attached to the router, not your WiFi password.
  • After you change the password and save, your router restarts and all devices must reconnect using the new password.
  • If you forget the new password, you can reset the router to factory settings by holding the reset button for 10 to 15 seconds, which erases all your settings.

What happens to devices already connected

When you save a new password, your router will restart. Devices that were connected will lose their connection and show "no internet" or "can't connect to this network." This is normal. You do not need to do anything to those devices — they will not automatically reconnect.

To reconnect each device, open its WiFi settings, select your network name, and enter the new password. Phones, tablets, and laptops all handle this the same way. Once you enter the new password correctly, the device reconnects and stays connected until you change the password again.

Finding your router's login information if you do not have the sticker

If the sticker on your router is missing or unreadable, try the most common factory defaults: username admin and password admin, or username admin and password password. Many routers ship with one of these combinations.

If those do not work, search online for "[your router brand and model] default username password." You can find your model number on the sticker or in your router's manual. If you still cannot log in, contact your internet service provider — they can often reset the router remotely or walk you through the process.

Choosing a strong new password

A strong WiFi password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, address, phone number, or anything else someone could guess from your social media. Do not use common words or patterns like "password123" or "qwerty."

Write down your new password and store it somewhere safe — a notebook in a drawer, a password manager like Bitwarden or 1Password, or even a photo on your phone stored in a locked folder. You will need it when you reconnect devices or when guests ask for the WiFi password.

What to do if you cannot log into the admin panel

If you have tried the default username and password and still cannot get in, your router may have been set up with a custom login that you or a previous owner created. If you do not remember it, you can reset the router to factory settings. Look for a small recessed button labeled "Reset" on the back or bottom of the router.

Using a paperclip or the tip of a pen, press and hold the reset button for 10 to 15 seconds while the router is powered on. The lights will flash and the router will restart. Once it boots back up, all settings — including the admin password and WiFi password — return to factory defaults. You can then log in with the default credentials and set up a new password from scratch.

Be aware that resetting erases any custom settings you made, such as port forwarding or parental controls. You will need to reconfigure those after the reset if you want them back.

Changing the password on your phone or computer instead

Some internet service providers offer a mobile app or a web portal where you can manage your WiFi settings without logging into the router directly. Comcast Xfinity, AT&T, and Verizon all have apps that let you change your password from your phone. Check whether your provider offers this option — it can be faster than using the router's admin panel.

To find out, search online for "[your internet provider] WiFi password change app" or log into your account on the provider's website and look for a "WiFi" or "Network" section. If your provider offers this, follow their instructions instead of the router method. The end result is the same: your new password takes effect after a brief restart.

Frequently Asked Questions

How often should I change my WiFi password?

There is no hard rule. Change it if you suspect someone has the old password, if you have guests who no longer visit, or if you want to refresh your security. Many people change it once or twice a year. If you live alone and trust everyone who has ever had the password, changing it less often is fine.

Can I change my WiFi password without restarting the router?

No. The router must restart to explore the new password. The restart usually takes 30 seconds to two minutes. During that time, all connected devices lose internet access temporarily.

What if I change the password and then forget it?

Reset the router to factory defaults by holding the reset button for 10 to 15 seconds. This erases the password you just set and returns it to the factory default. You can then log back in and set a new password. Write it down this time.

Do I need to change the admin password too?

Yes, if you have not already. The admin password protects access to your router's settings. Change it from the default to something only you know. This prevents someone on your network from logging in and changing your WiFi settings without permission.

Will changing my password disconnect my smart home devices?

Yes. Smart speakers, security cameras, thermostats, and other connected devices will lose connection when you change the password. You will need to reconnect each one using the new password through its app or settings menu. Check the device's manual if you are unsure how to reconnect it.
