Why you change the password on your phone, not your router
When you change your WiFi password, you are logging into your router's settings through your phone's web browser or an app. The router itself stores the password — your phone just connects to it. So even though you are holding your phone, you are actually changing the settings on the device that broadcasts your WiFi signal, which sits somewhere in your home (usually plugged into a wall or your modem).
Your phone does not store or broadcast WiFi. It only receives the signal. This is why changing the password on your phone's WiFi settings menu does not work — that menu only lets you forget networks or view what you are connected to, not change what the router broadcasts.
Key Takeaways
- You change your WiFi password by logging into your router's settings through a web browser on your phone, not through your phone's WiFi settings menu.
- You will need your router's IP address (usually printed on the router itself or in your manual) and your router's admin username and password.
- The exact steps differ by router brand — TP-Link, Netgear, Linksys, and others have different layouts, but the process is the same: open a browser, type the IP address, log in, find the wireless or WiFi settings, and change the password.
- After you save the new password, all devices will disconnect and you will need to reconnect them using the new password.
- If you have forgotten your router's admin password, you can reset the router to factory settings by holding the reset button for 10 to 15 seconds, but this erases all your settings.
Find your router's IP address and login information
Before you open your browser, you need two pieces of information: your router's IP address (a set of numbers like 192.168.1.1) and your router's admin username and password (different from your WiFi password). Most routers print this information on a sticker on the back or bottom of the device itself.
Look for a sticker that lists "IP Address", "Default Gateway", or "Router Address" — this is the number you will type into your phone's browser. The sticker also usually shows a default username (often "admin") and password. If you have changed the admin password before and cannot remember it, you will need to reset the router, which is covered later in this article.
If the sticker is missing or unreadable, check your router's manual or the manufacturer's website. You can also search online for "[your router model] default IP address" — for example, "Netgear Nighthawk default IP address".
Open your router's settings in your phone's browser
Open any web browser on your phone — Chrome, Safari, Firefox, or Edge all work. In the address bar at the top, type the IP address you found on your router. Do not use a search engine; type it directly into the address bar. For example, if your IP address is 192.168.1.1, type exactly that.
Press Enter or Go. Your phone will load a login page that looks different depending on your router brand. You may see a warning that the connection is not find — this is normal for router login pages. Tap through any warnings and continue.
On the login page, enter the username and password from the sticker on your router. Tap Login or Submit. If the page does not load or you see an error, make sure you typed the IP address correctly and that your phone is connected to that WiFi network.
Locate the wireless or WiFi settings
Once you are logged in, you will see a dashboard or menu. The layout depends on your router brand, but you are looking for a section called "Wireless", "WiFi", "Wireless Settings", or "Network Settings". This section is usually in a left-side menu or a row of tabs at the top.
Some routers separate settings for 2.4 GHz and 5 GHz networks — these are two different frequency bands your router can broadcast on. You may see both listed. If you want to change the password for both bands, you will need to update each one separately. If you only see one, your router broadcasts on one band only.
Tap or click on the wireless settings section. You should now see a field labeled "Wireless Password", "WiFi Password", "Passphrase", or "Pre-Shared Key (PSK)". This is where you change your password.
Change the password and save your settings
Tap the password field and clear the current password. Type your new password. WiFi passwords are case-sensitive, meaning uppercase and lowercase letters are treated as different characters. Choose a password that is at least 8 characters long and includes a mix of letters, numbers, and symbols if possible — this makes it harder for others to guess.
Write down or save your new password somewhere safe before you proceed. Once you save these settings, you will need the new password to reconnect all your devices.
Look for a "Save", "explore", or "OK" button and tap it. Your router will restart, which usually takes 30 seconds to 2 minutes. During this time, all devices will disconnect from WiFi. Once the router restarts, your new password is active.
Reconnect your devices with the new password
After the router restarts, go to your phone's WiFi settings menu (the one where you normally choose which network to connect to). You should still see your network name listed. Tap it and enter your new password when prompted. Your phone will reconnect.
Repeat this process on every device that uses your WiFi — computers, tablets, smart speakers, smart TVs, and any other connected devices. They will all show as disconnected until you enter the new password on each one.
If a device does not reconnect after you enter the correct password, try "forgetting" the network in that device's WiFi settings, then reconnecting from scratch. This clears out the old password from the device's memory.
What to do if you forgot your router's admin password
If you cannot log into your router because you have forgotten the admin password, you can reset the router to factory settings. This erases all your custom settings — including your WiFi password — and returns the router to the state it was in when you first bought it.
Locate the small reset button on the back or bottom of your 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 on the router will flash, indicating a reset is happening. Release the button and wait for the router to restart, which takes about 2 minutes.
Once the router restarts, log back in using the default username and password from the sticker on the router. You can then set a new admin password and a new WiFi password. This process is the same as changing the password normally — just follow the steps above starting from "Open your router's settings in your phone's browser".
Frequently Asked Questions
Can I change my WiFi password without resetting the router?
Yes. Resetting the router should only be necessary if you have forgotten your admin password. If you can log into your router's settings, you can change just the WiFi password without affecting anything else. The steps above show you how to do this without a reset.
What is the difference between my WiFi password and my router's admin password?
Your WiFi password is what you give to guests or use on your phone to connect to the internet. Your router's admin password is what you use to log into the router's settings to make changes. They are separate. You can change your WiFi password without knowing your admin password only if you have already logged in once before.
Why does my phone keep disconnecting after I change the password?
This usually means your phone is trying to reconnect with the old password still stored in its memory. Go to your phone's WiFi settings, find your network name, and tap "Forget This Network". Then reconnect by selecting the network again and entering your new password. This clears the old password from your phone's memory.
Do I need to change my password if I reset my router?
Yes. When you reset your router, it returns to the default WiFi password that came from the factory. This password is usually printed on the router's sticker and is the same for all routers of that model, so anyone could guess it. You should change it to a unique password as soon as the router restarts.
Can I change my WiFi password on my phone if I am not connected to that WiFi?
No. Your phone needs to be connected to the WiFi network in order to reach your router's settings page. If you are not connected, connect first, then follow the steps above. If you cannot connect because you forgot the password, you will need to reset the router.
