Log into your router's admin panel to change the password

Your WiFi password lives in your router's settings, not on your computer or phone. To change it, you need to open your router's admin panel — a web page that controls how your router works. You'll need the router's IP address (usually printed on the router itself or in your manual) and the admin username and password (also usually on the router or in paperwork that came with it).

Open a web browser on any device connected to your WiFi. Type the router's IP address into the address bar — common ones are 192.168.1.1 or 192.168.0.1, but check your specific router. You'll see a login screen. Enter the admin username and password. Once you're in, look for a section called "Wireless", "WiFi", "Security", or "Network Settings" — the exact name varies by router brand.

Key Takeaways

  • Your router's IP address and admin login are usually printed on the router itself or in the documentation that came with it.
  • The WiFi password setting is typically under "Wireless", "WiFi", or "Security" in your router's admin panel, not under a general settings menu.
  • Change the password to something you can remember but others cannot easily guess — avoid birthdays, addresses, or names of family members.
  • After you save the new password, all your devices will disconnect and you'll need to reconnect them using the new password.
  • If you've lost the admin password to your router, you can reset the router to factory settings, but this erases all your custom settings.

Find the WiFi password field and choose a strong new one

Once you're in the wireless settings section, look for a field labeled "Password", "Passphrase", "Pre-Shared Key", or "PSK". This is where your current WiFi password is stored. Click in that field and delete the old password, then type in your new one.

A strong WiFi password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, address, birthday, or the name of your street — these are easy for someone nearby to guess. A phrase like "BlueMoon$Kitchen42" is much harder to crack than "Password123" or "Smith2024".

Save your changes and reconnect your devices

After you type the new password, look for a button labeled "Save", "Apply", "OK", or "Confirm" — usually at the bottom of the page. Click it. Your router will restart, which takes about 30 seconds to a minute. During this time, your WiFi will go offline briefly.

Once the router comes back online, your devices will still be connected to the WiFi network name, but they won't have internet access because they're using the old password. You'll need to "forget" the network on each device and reconnect using the new password. On most phones and computers, you can do this by going to WiFi settings, selecting your network, and choosing "Forget" or "Remove", then reconnecting and entering the new password when prompted.

What to do if you can't remember the admin password

If you've forgotten the admin password to your router (the password that lets you into the settings panel), you can reset the router to factory settings. Look for a small reset button on the back or bottom of the router — it's usually recessed so you need a paperclip or pen to press it. Hold it down for 10 to 15 seconds while the router is powered on. The router will restart and return to its original settings.

After a factory reset, you'll need to log back into the admin panel using the default username and password printed on the router. Then you can set a new admin password and a new WiFi password. Keep both of these somewhere safe — a password manager or a written note in a secure place — so you don't lose them again.

Change your admin password too, for security

While you're in the router settings, change the admin password as well. This is the password you use to log into the settings panel itself, separate from your WiFi password. Many routers come with a default admin password like "admin" or "password", and leaving it unchanged means anyone who connects to your WiFi could potentially access your router settings and change your WiFi password or other settings.

Look for a section called "Administration", "System Settings", or "Account Settings" in your router's admin panel. Find the field for admin password and change it to something strong and unique. This password doesn't need to be as long as your WiFi password, but it should be something you can remember and that others can't guess.

Troubleshoot if devices won't reconnect after the password change

Sometimes a device will refuse to connect even after you've entered the new password correctly. The most common fix is to restart the device. Turn it off completely, wait 10 seconds, and turn it back on. Then try connecting to the WiFi again.

If restarting doesn't work, try forgetting the network and reconnecting. On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, find your network, and click "Forget". On Mac, go to System Preferences > Network > WiFi, click "Advanced", select your network from the list, and click the minus button. On phones, go to WiFi settings, tap your network name, and choose "Forget" or "Remove". Then reconnect and re-enter the new password carefully — passwords are case-sensitive, so "BlueMoon" is different from "bluemoon".

Change your password regularly to keep your network secure

You don't need to change your WiFi password every month, but changing it once or twice a year is a good practice. If you suspect someone has been using your WiFi without permission — for example, your internet is slower than usual or you see unfamiliar device names in your router's connected devices list — change the password immediately. This will disconnect anyone who was using the old password.

If you live in an apartment or have guests over frequently, you might want to change the password more often. Some routers let you create a separate guest network with its own password, which is useful if you want to give people temporary WiFi access without sharing your main network password. Check your router's admin panel for a "Guest Network" option.

Frequently Asked Questions

Will changing my WiFi password delete my files or settings?

No. Changing your WiFi password only affects how devices connect to the internet. Your files, photos, emails, and all your device settings stay exactly as they are. You'll just need to reconnect to the WiFi using the new password.

What if I don't know my router's IP address?

Check the back or bottom of your router — the IP address is usually printed there along with the admin username and password. If you can't find it, look in the documentation that came with your router. You can also search online for "[your router brand and model] default IP address" to find it.

Can I change my WiFi password from my phone instead of a computer?

Yes. Open a web browser on your phone, type your router's IP address into the address bar, and log in with your admin credentials. The process is the same as on a computer, though the layout might look slightly different on a smaller screen.

How long does it take for the password change to take effect?

The change takes effect as soon as you save it and the router restarts, which usually takes 30 seconds to a minute. After that, devices using the old password will lose internet access and need to reconnect with the new password.

What happens if I change the password while someone is using my WiFi?

They'll be disconnected immediately and won't be able to reconnect unless they know the new password. This is useful if you want to remove someone from your network.
