Where to change your WiFi password
Your WiFi password lives in your router's settings, not in your computer or phone. To change it, you log into the router itself through a web browser or an app, find the wireless settings section, and type in a new password. The router then broadcasts that new password to any device trying to connect.
You will need two things before you start: the router's admin password (different from your WiFi password) and the router's IP address or web address. Most routers print both on a sticker on the back or bottom of the device. If you have never changed the admin password, it is usually the factory default — often "admin" for both username and password, or sometimes just a blank username with "admin" as the password.
The exact steps differ slightly depending on whether your router is from your internet provider (like a Comcast or AT&T device) or a separate router you bought yourself. Both follow the same general path, but the menu names and button locations vary.
Key Takeaways
- Your WiFi password is stored in the router's settings, which you reach by typing the router's IP address into a web browser.
- You will need the router's admin password to log in — this is printed on a sticker on the router itself if you have never changed it.
- The wireless settings section is usually labeled "WiFi", "Wireless", or "SSID", and you can change the password without disconnecting your devices.
- After you save a new password, devices already connected stay online, but new devices will need the new password to join.
- If you forget the new password, you can reset the router to factory settings, but this erases all your custom settings.
Finding your router's login address and admin password
Look at the back or bottom of your router for a sticker. It will show an IP address (usually something like 192.168.1.1 or 192.168.0.1) or a web address (like routerlogin.net or myrouter.local). It will also show a default username and password for the admin account.
Write these down or take a photo. If the sticker is missing or worn away, try typing one of the common addresses into your browser: 192.168.1.1, 192.168.0.1, or 192.168.100.1. One of these will usually work. If none of them load, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully boot up.
If you have changed the admin password before and cannot remember it, you will need to reset the router. Most routers have a small reset button on the back that you hold down for 10 to 15 seconds with a paperclip or pen. This erases all settings and returns the router to factory defaults, so use this only as a last resort.
Logging into your router through a web browser
Open any web browser — Chrome, Firefox, Safari, Edge, it does not matter. In the address bar at the top, type the IP address or web address from your router's sticker. Press Enter. A login page should appear asking for a username and password.
Type the username and password from the sticker. Most routers use "admin" for both, but some use "admin" with a blank password, or other combinations. If the first attempt does not work, try the sticker information again carefully — usernames and passwords are case-sensitive.
Once you log in, you will see a dashboard or home page with various settings sections. Look for a section labeled "Wireless", "WiFi", "WLAN", or "Network". The exact name depends on your router brand. If you cannot find it on the main page, look for a menu on the left side or top of the page.
Changing the WiFi password in wireless settings
Click on the wireless or WiFi section. You will see fields for the network name (called the SSID) and the password. The password field might be labeled "Passphrase", "Security Key", "Pre-Shared Key", or "WiFi Password".
Click in the password field and clear the current password. Type your new password. WiFi passwords are case-sensitive and can include uppercase letters, lowercase letters, numbers, and special characters like ! @ # $ % ^ & *. A strong password is at least 12 characters long and mixes all four types. Write it down somewhere safe or store it in a password manager.
Do not change the network name (SSID) unless you have a reason to — changing it can confuse devices that are already connected. Once you have entered the new password, look for a "Save", "explore", or "OK" button and click it. The router will process the change, which usually takes 10 to 30 seconds.
What happens to your devices after you change the password
Devices that are already connected to your WiFi will stay connected and keep working. You do not need to restart them. However, if a device disconnects for any reason — or if someone tries to connect a new device — they will need the new password to rejoin.
To connect a device with the new password, go to the WiFi network list on that device, select your network name, and when prompted for the password, type the new one you just created. On phones and tablets, this is usually in Settings under WiFi. On computers, it is in the network settings or system tray.
If you have a lot of devices, you may want to wait until everyone is home and ready to reconnect before you change the password. Otherwise, you will spend time helping people re-enter it on their phones, laptops, smart TVs, and other gadgets.
Using your router's mobile app instead of a web browser
Many modern routers come with a smartphone app that lets you change settings without opening a web browser. Check your router's box or manual for the app name, or search your phone's app store for your router brand name plus "app" or "WiFi".
read and open the app, then log in with the same admin username and password. The app will guide you to the wireless settings section. The steps are the same as the web browser method — find the password field, enter a new password, and save. Apps sometimes make this process slightly simpler by hiding advanced options you do not need.
If you prefer the app but cannot find it, the web browser method works just as well. Both reach the same router settings.
Troubleshooting if the password change does not work
If you click Save or explore and nothing happens, check that you are still logged into the router. Some routers log you out after a few minutes of inactivity. Go back to the login page, enter your admin credentials again, and try saving the new password once more.
If you see an error message, write down the exact text and search for it along with your router model number. Different routers show different error messages, and the solution depends on what went wrong. Common issues include the password being too short, containing characters the router does not accept, or the router running out of memory.
If the router seems to freeze or stop responding, unplug it for 30 seconds and plug it back in. Wait for all the lights to stabilize before trying to log in again. If it keeps freezing, your router may need a firmware update or may be overheating — make sure it has space around it and is not in a hot closet or near a heat source.
Frequently Asked Questions
Do I need to restart my router after changing the WiFi password?
No. The password change takes effect when ready after you click Save. You do not need to restart the router or your devices. Devices already connected will keep working without interruption.
What is the difference between the WiFi password and the admin password?
The WiFi password is what guests and your devices type to connect to the internet. The admin password is what you type to log into the router's settings to make changes. They are separate and do not have to be the same. You should change the admin password too if it is still the factory default, because anyone who knows the default can log in and change your settings.
Can I change my WiFi password from my phone or computer instead of the router?
No. Your phone or computer connects through the WiFi network, but the password itself is stored in the router. You must log into the router's settings to change it. Some routers have an app that makes this easier, but you are still logging into the router, not your device.
What if I forget the new password I just created?
You can reset the router to factory settings by holding the reset button for 10 to 15 seconds. This erases all your settings, including the new password, and returns the router to its original state. You will then need to log back in with the factory default credentials and set everything up again.
Can I change the WiFi password while I am away from home?
Only if your router has a remote management feature and you set it up beforehand. Most home routers do not allow remote access for security reasons. If you need to change it while away, you will need to ask someone at home to do it, or wait until you return.
