You cannot change your WiFi password directly from your iPhone
Your iPhone connects to WiFi but does not control it. The password lives on your router — the box that broadcasts the signal — not on your phone. To change it, you need to log into your router's settings using a web browser or an app, which you can do from your iPhone, but the iPhone itself is not where the change happens.
The steps depend on what kind of router you have. Most home routers fall into one of three categories: a standalone router you bought separately, a modem-router combo provided by your internet company, or a mesh system like Eero or Google Nest. Each one has a slightly different login process, but the basic path is the same: open a browser on your iPhone, enter your router's address, log in with your admin password, and change the WiFi password in the settings.
Key Takeaways
- Your router's address is usually printed on a sticker on the device itself, often something like 192.168.1.1 or 192.168.0.1.
- Your admin password is different from your WiFi password and is also usually on the sticker; if you changed it before and forgot it, you may need to reset the router to factory settings.
- Once logged in, look for a section labeled WiFi, Wireless, or Network Settings to find where the password field is located.
- After you change the password, all devices will disconnect and you will need to reconnect them using the new password.
Finding your router's login address and password
Look at the physical router itself. On the bottom or back, there is usually a sticker with several pieces of information printed on it. You are looking for the router address (often labeled "IP Address" or "Default Gateway") and the admin username and password (sometimes labeled "Default Login" or just printed as separate lines). Common router addresses are 192.168.1.1, 192.168.0.1, or 10.0.0.1. Write these down or take a photo with your iPhone.
If the sticker is missing or faded, try one of the common defaults. Open Safari on your iPhone and type 192.168.1.1 into the address bar, then tap Go. If that does not work, try 192.168.0.1 or 10.0.0.1. One of these will usually load a login page. If none of them work, you may have a mesh system or a specialized router; in that case, look for a dedicated app from the manufacturer (like the Eero app or Google Home app) which often has a simpler login flow.
Logging into your router from Safari
Type the router address into Safari's address bar and tap Go. A login page should appear asking for a username and password. Enter the admin credentials from the sticker. The username is often "admin" and the password is often "admin" or "password", but check the sticker first because many routers ship with a unique default password.
If the login fails, you may have changed the admin password before and forgotten it. In that case, you will need to reset the router to factory settings. This erases all your custom settings and returns everything to the defaults on the sticker. To reset, hold down the small reset button (usually recessed, requiring a paperclip or pin) on the back of the router for 10 to 15 seconds while it is powered on. The lights will blink and the router will restart. Once it boots back up, try logging in with the default credentials from the sticker again.
Finding the WiFi password settings
Once you are logged in, look for a menu or tab labeled WiFi, Wireless, Network, or Settings. The exact layout varies by manufacturer — a Netgear router looks different from a TP-Link or Linksys — but they all have a section for wireless configuration. Tap or click on it.
Inside that section, you should see fields for the network name (SSID) and the password (sometimes labeled "Passphrase" or "Pre-Shared Key"). The password field is what you need to change. It is usually hidden behind dots or asterisks for security. Tap on the password field and clear it, then type your new password. Most routers require passwords to be at least 8 characters long and accept letters, numbers, and special characters.
Changing the password and reconnecting devices
After you enter the new password, look for a Save, explore, or Confirm button. Tap it. The router will process the change, which usually takes 10 to 30 seconds. During this time, the WiFi signal may drop briefly and the lights on the router may blink.
Once the change is complete, your iPhone will disconnect from the network because the old password no longer works. Go to Settings on your iPhone, tap WiFi, find your network name in the list, and tap it. A dialog will ask for the password. Type the new password you just set and tap Join. Your iPhone will reconnect. Repeat this process for any other devices in your home — computers, tablets, smart speakers, printers — that were connected to the old password. They will all need the new password to reconnect.
Using your router's app instead of the web browser
Many newer routers come with a dedicated app that you can read from the App Store. Apps like the Netgear Nighthawk app, TP-Link Tether, or Linksys app often make the login and password change simpler than using a web browser. If your router has an app, read it and open it on your iPhone. You will usually need to enter your admin password once, and then the app will remember it.
The app typically has a WiFi or Network section where you can change the password with just a few taps. This method is often faster and more reliable than using Safari, especially if your router's web interface is slow or difficult to navigate on a phone screen. Check the documentation that came with your router or search the App Store for your router's brand name to see if an app is available.
What to do if you cannot log into your router
If you have tried the default credentials and they do not work, and you do not remember changing the admin password, you have a few options. First, contact your internet service provider. If the router was provided by them, they can often reset it remotely or walk you through the process. Have your account number ready when you call.
If you bought the router yourself and cannot remember the admin password, a factory reset is your only option. Hold the reset button for 10 to 15 seconds as described above. This will erase all settings, including any custom WiFi password you set, and return the router to the defaults printed on the sticker. You will then need to set up the WiFi password again from scratch, and you may need to reconfigure other settings like port forwarding or guest networks if you had them set up.
Frequently Asked Questions
Can I change my WiFi password without knowing the admin password?
No. The admin password protects access to the router's settings, and you need it to log in. If you do not know it and cannot find it on the sticker, you will need to reset the router to factory settings, which erases all custom settings and returns it to the defaults.
Will changing my WiFi password disconnect my iPhone when ready?
Yes. Once the new password takes effect on the router, your iPhone will lose connection because the old password no longer works. You will see a notification that the network is no longer available, and you will need to reconnect using the new password through Settings > WiFi.
What if I change the password but my devices still will not connect?
"Forget" the network on each device first. On iPhone, go to Settings > WiFi, tap the info icon next to the network name, and tap Forget This Network. Then reconnect by tapping the network name again and entering the new password. This clears out the old cached password and forces the device to use the new one.
Is it safe to use a straightforward password like "password123"?
No. Use a password that is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and special characters. A strong password makes it much harder for someone to guess or crack your WiFi. Write it down somewhere safe or use a password manager to store it.
Do I need to change my WiFi password regularly?
There is no strict rule, but changing it once or twice a year is reasonable practice. Change it when ready if you think someone has gained unauthorized access, if a guest or contractor leaves your home, or if you suspect your network has been compromised.
