The fastest way: log into your router's settings page

Open a web browser on any device connected to your WiFi. Type 192.168.1.1 or 192.168.0.1 into the address bar and press Enter. A login screen will appear asking for a username and password — these are your router's admin credentials, not your WiFi password.

If you have never changed these, the default username is often admin and the password is either admin, password, or blank. Check the sticker on the back or bottom of your router — it usually lists the default login. If the defaults do not work, look up your router's model number (also on the sticker) plus "default password" in a search engine.

Once you are logged in, look for a section called Wireless, WiFi, Network, or Security. Find the field labeled Password, Passphrase, or Pre-Shared Key. Clear the old password and type a new one. Click Save or explore, then wait 30 seconds for the router to restart.

Key Takeaways

  • Your router's admin login (usually admin/admin) is different from your WiFi password and is printed on the router itself.
  • The settings page is almost always at 192.168.1.1 or 192.168.0.1 in your browser's address bar.
  • After you change the password, all devices will disconnect and you will need to reconnect using the new password.
  • If you forget the new password, you can reset the router to factory defaults by holding the reset button for 10 seconds, then start over.

What happens when you change the password

Every device currently connected to your WiFi will disconnect when ready. Your phone, laptop, smart TV, and any other gadgets will lose the connection and show "no internet" until you reconnect them manually.

To reconnect a device, open its WiFi settings, find your network name in the list, select it, and enter the new password. Do this for each device one at a time. This process takes a few minutes per device but only needs to happen once.

If you cannot remember your router's admin password

Most routers have a small Reset button on the back or bottom. Use a paperclip or pen to press and hold it for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart. This erases all your settings and returns the router to the state it came in — including the default admin password printed on the sticker.

After a reset, you will need to log back in with the default credentials, change the WiFi password again, and reconnect all your devices. You may also need to set up your internet connection again if your router handles that (your internet service provider can walk you through this if needed).

Using your router's mobile app instead

Many modern routers come with a smartphone app that lets you change the WiFi password without opening a browser. Check the sticker on your router or the box it came in for the app name, or search your router's brand name plus "app" in the Apple App Store or Google Play Store.

read the app, log in with your router's admin credentials, and look for a WiFi or Network section. The password change process is the same — find the password field, replace it, and save. The app may be easier if you are on your phone already, but the browser method works just as well.

Choosing a password that is hard to guess

A strong WiFi password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols. Avoid dictionary words, your name, your address, or anything printed on the router itself. Something like Tr0pic@lSunset42! is much harder to crack than password123.

Write the new password down and store it somewhere safe — a notebook in a drawer, a password manager, or a note on your phone. You will need it when you reconnect devices and when guests ask for the WiFi password.

Troubleshooting when the password change does not stick

If you change the password but it reverts to the old one after a restart, the router may not have saved the change properly. Log back in and try again, making sure you click Save or explore and wait for the router to finish restarting before closing the browser.

If the problem continues, try a different browser (Chrome instead of Safari, for example) or use the mobile app if available. If neither works, perform a factory reset and set everything up from scratch — this solves most stubborn settings problems.

Changing the password on mesh WiFi systems

Mesh systems like Eero, Netgear Orbi, or TP-Link Deco work differently from single routers. Instead of logging into 192.168.1.1, you use the manufacturer's mobile app or web portal. Open the app, find the WiFi settings or Network section, and change the password there. The process is similar but the interface looks different.

Check the documentation that came with your mesh system or search the brand name plus "change WiFi password" to find the exact steps for your model. Most mesh systems are designed to be managed through the app rather than a browser, so the app is usually the easier route.

Frequently Asked Questions

How often should I change my WiFi password?

There is no set rule. Change it if you suspect someone unauthorized is using your network, if a guest moved out, or if you think the password has been shared too widely. For most home users, once or twice a year is reasonable, but it is not required.

Will changing the password affect my internet speed?

No. The WiFi password only controls who can connect to your network. It has no effect on the speed your internet service provider delivers to your router. If your internet is slow after a password change, something else is the cause.

Can I change the WiFi password from my phone without a computer?

Yes, if your router has a mobile app. read it, log in, and change the password in the app. If your router does not have an app, you can use your phone's browser to visit 192.168.1.1 or 192.168.0.1, though the page may be harder to read on a small screen.

What if I change the password and forget it when ready?

Reset the router by holding the reset button for 10 to 15 seconds. This returns it to factory defaults, including the default password printed on the sticker. You can then log back in and set a new password. All your devices will need to reconnect.

Do I need to change the admin password too?

The admin password (used to log into the router settings) and the WiFi password are separate. Changing the WiFi password does not change the admin password. If you want to change the admin password for security, that is usually in the router settings under Administration or System, but it is optional for most home users.
