You change your WiFi password through your router, not through your iPhone

Your iPhone connects to WiFi but does not store or control the password itself — your router does. To change the password that devices use to join your network, you log into your router's settings from any device on that network, including your iPhone. The iPhone is just the tool you use to reach those settings.

This is the source of confusion: people expect a WiFi settings menu on the phone, but the phone is a guest on the network. The owner of the network — the router — is where the password lives. Once you change it on the router, every device on your network will need the new password to reconnect.

Key Takeaways

  • WiFi passwords are stored on your router, not your iPhone, so you must log into the router's settings to change it.
  • You can access your router from your iPhone by opening a web browser and typing your router's IP address, usually 192.168.1.1 or 192.168.0.1.
  • You will need your router's admin username and password, which is often printed on a sticker on the back or bottom of the router.
  • After you change the password on the router, your iPhone will disconnect and you will need to enter the new password to reconnect.
  • All other devices on your network will also need the new password before they can connect again.

Find your router's IP address and admin login

Before you can change anything, you need two pieces of information: the address where your router's settings live (its IP address) and the username and password to log in. Both are usually printed on a sticker attached to the back or bottom of your router.

Look for a sticker that shows something like "192.168.1.1" or "192.168.0.1" — that is the IP address. On the same sticker you will see a username (often "admin") and a password. Write these down or take a photo. If the sticker is missing or worn away, check the router's manual or the manufacturer's website — most routers use the same defaults.

If you have never changed the admin password before, it is almost certainly the factory default. Common defaults are "admin" for both username and password, or "admin" with a blank password. If you changed it in the past and forgot it, you will need to reset the router to factory settings, which erases all your WiFi settings — see the FAQ section for that scenario.

Open your router's settings on your iPhone

Open Safari or any web browser on your iPhone. In the address bar at the top, type the IP address from your router's sticker — for example, 192.168.1.1 — and tap Go. The page may take a few seconds to load.

You will see a login screen asking for a username and password. Enter the admin username and password from the sticker. Tap the login button. If the page does not load or you see an error, try the other common IP address: 192.168.0.1. If neither works, your router may use a different address — check the manual or the manufacturer's support page.

Locate the WiFi password setting

Once you are logged in, you will see your router's control panel. The layout varies by manufacturer — TP-Link, Netgear, Linksys, and others all look different. Look for a menu item labeled "Wireless," "WiFi," "Network," or "Security." Tap it.

Inside that section, find the field labeled "Password," "Passphrase," "Pre-Shared Key," or "PSK." This is where your current WiFi password is stored. You may also see a field for the network name (SSID) — do not change that unless you want to rename your network. Leave that alone and focus only on the password field.

Enter your new password and save

Tap the password field and clear the old password. Type your new password. WiFi passwords are case-sensitive, so uppercase and lowercase letters matter. Make it at least 12 characters long and include a mix of letters, numbers, and symbols if you can — this makes it harder for others to guess.

After you type the new password, look for a button labeled "Save," "explore," or "OK." Tap it. The router will process the change, which usually takes 10 to 30 seconds. You may see a message saying the settings have been saved, or the page may refresh on its own.

Reconnect your iPhone with the new password

Once the router has saved the new password, your iPhone will disconnect from WiFi automatically — the old password no longer works. You will see a notification that the network is no longer available or that the password is incorrect.

Go to Settings on your iPhone, tap WiFi, and find your network name in the list. Tap it and enter your new password in the field that appears. Make sure you type it exactly as you entered it on the router — spaces, capitals, and symbols all matter. Tap Join. Your iPhone will reconnect within a few seconds.

Update the password on your other devices

Every device that was connected to your old WiFi password will now show an error when it tries to connect. This includes computers, tablets, smart speakers, security cameras, printers, and anything else on your network.

On each device, go to its WiFi settings, find your network, and enter the new password. The process is slightly different on each device type, but the principle is the same: forget the old network and reconnect with the new password. Devices that are not actively used may not try to reconnect until you turn them on, so do not be surprised if your printer or smart speaker does not ask for the new password until you use it again.

Frequently Asked Questions

What if I forgot my router's admin password?

You will need to reset the router to factory settings. Hold down the reset button (usually a small hole on the back) for 10 to 15 seconds with a paperclip or pin. The router will restart and all settings, including the WiFi password, will return to the factory defaults printed on the sticker. You can then log in with those defaults and set a new password.

Can I change the WiFi password from my iPhone without logging into the router?

No. Your iPhone can only connect to the network — it cannot change the network's settings. You must access the router's control panel, which requires logging in with the admin credentials. The router is the only device that can change the password.

My router does not have an IP address sticker. How do I find it?

Open Settings on your iPhone, tap WiFi, then tap the information icon (i) next to your network name. Look for a field labeled "Router" or "Gateway" — that is your router's IP address. Write it down and use it to log in.

Do I have to change the password on my iPhone first before changing it on the router?

No. You change the password on the router first, then your iPhone will disconnect, and then you reconnect your iPhone with the new password. Changing anything on your iPhone's WiFi settings will not change the actual network password.

What if the router settings page looks completely different from what you described?

Router interfaces vary widely by brand and model. If you cannot find a WiFi or Wireless section, look for "Network Settings" or check the router's manual. You can also search online for "[your router model] how to change WiFi password" — manufacturers publish step-by-step guides for their specific routers.
