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

Your iPhone connects to WiFi but does not control it. The password lives on your router — the box that broadcasts the signal — so you have to log into the router itself to change it. Your iPhone will then reconnect using the new password once you update it in your WiFi settings.

This means you need two things: access to your router (usually in a closet, basement, or mounted on a wall) and the router's admin password, which is different from your WiFi password. If you do not know the admin password, you can reset the router to factory settings, but that erases all your customizations.

The steps differ slightly depending on your router brand, but the process is the same across all of them: log in to the router's settings page, find the WiFi password field, change it, save, and then reconnect your iPhone using the new password.

Key Takeaways

  • WiFi passwords are set on your router, not on your iPhone, so you must access the router's settings page through a web browser or app.
  • You will need your router's admin password to log in; this is printed on a sticker on the router or in your account with your internet provider.
  • After you change the password on the router, your iPhone will forget the old WiFi network and you will need to reconnect it with the new password.
  • If you do not know the admin password, you can factory reset the router by holding the reset button for 10 to 15 seconds, but this erases all settings.

Finding your router's admin password

Look for a sticker on the bottom or back of your router. It usually shows the WiFi network name, the default WiFi password, and the admin username and password. The admin credentials are often "admin" for the username and a default password printed on the sticker.

If the sticker is missing or worn, check your internet provider's account page online. Log into your account with Comcast, Verizon, AT&T, or whoever provides your internet, and look for a section labeled "Equipment," "Modem," or "Router." The admin password is sometimes listed there, or you can reset it through your account.

If you cannot find it anywhere, you can reset the router to factory settings. Locate the small reset button (usually recessed so you need a paperclip or pen to press it), hold it for 10 to 15 seconds while the router is powered on, and release. The router will restart and return to its default settings, including the default admin password on the sticker.

Logging into your router on an iPhone

Open Safari or any web browser on your iPhone. In the address bar, type the router's IP address. For most home routers, this is 192.168.1.1 or 192.168.0.1. If neither works, check the sticker on your router or your internet provider's documentation.

Press Go. A login page will appear asking for a username and password. Enter the admin username and password from the sticker or your provider's account. Press Log In or Submit.

You are now in your router's settings page. This page looks different depending on your router brand — it might be made by TP-Link, Netgear, Linksys, Arris, or another manufacturer — but the layout is similar across all of them. Look for a section labeled "WiFi," "Wireless," "Network," or "Settings."

Changing the WiFi password in your router settings

Once you are logged in, find the WiFi settings section. This is usually on the left side of the page or in a menu at the top. Look for a tab or link that says "WiFi," "Wireless," "Network Settings," or "Security."

Inside that section, find the field labeled "WiFi Password," "Passphrase," "Pre-Shared Key," or "PSK." This is where your current password is stored. Click or tap on the field and delete the old password, then type your new password.

Make your new password at least 12 characters long and mix uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, address, or obvious words. Write down the new password somewhere safe before you save it.

Look for a button labeled "Save," "explore," "Submit," or "OK" and tap it. Your router will restart and explore the new password. This usually takes 30 seconds to 2 minutes. During this time, all devices will lose their WiFi connection.

Reconnecting your iPhone to WiFi with the new password

Once the router has restarted, open Settings on your iPhone and tap WiFi. Your network name will still appear in the list, but it will show "Not Connected" or a warning symbol because your iPhone still has the old password stored.

Tap your network name. A dialog will appear saying the password is incorrect or asking you to enter the password. Tap "Forget This Network" first, then tap your network name again from the list.

When the password prompt appears, type your new WiFi password exactly as you entered it on the router. Capitalization and special characters matter. Tap Join. Your iPhone will connect to the network and you will see a checkmark next to the network name.

What to do if you cannot access the router settings page

If you type the router's IP address and nothing loads, make sure your iPhone is still connected to the WiFi network. You need an active connection to reach the router's settings page. If you are not connected, tap your network name in Settings and enter the current password.

If the login page loads but you cannot log in, double-check the admin username and password. These are different from your WiFi password. If you have tried the default credentials and they do not work, your router may have been customized by a previous owner or your internet provider. Contact your provider's support line and provide your account number; they can reset the admin password or walk you through the process.

If you are using a combined modem and router (one box that does both), the process is the same, but the IP address might be different. Check the sticker or your provider's documentation for the correct address.

Changing the password on a mesh WiFi system

If you have a mesh system like Eero, Netgear Orbi, or TP-Link Deco, the process is slightly different. Instead of logging into the router directly, you use the manufacturer's app on your iPhone. read the app from the App Store, log in with your account, and look for a WiFi Settings or Security section.

Inside the app, find the option to change your WiFi password. Enter your new password, save it, and the app will push the change to all nodes in your mesh system at once. Your iPhone will disconnect and you will reconnect using the new password, just as with a standard router.

Mesh systems are often easier to manage from an app than from a browser, and the app works the same way whether you are at home or away. If you lose access to the app, you can still reset the system by holding the reset button on one of the nodes.

Frequently Asked Questions

Will changing my WiFi password disconnect all my devices?

Yes. All devices connected to your WiFi will lose the connection when the router saves the new password. They will stay disconnected until you enter the new password on each one. Devices like smart speakers, security cameras, and printers will also need the new password entered in their settings or apps.

What is the difference between my WiFi password and my admin password?

Your WiFi password is what you type on your iPhone to connect to the network. Your admin password is what you type to log into the router's settings page. They are completely separate. You can change your WiFi password without knowing the admin password only if you have already logged into the router once.

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

No. Your iPhone connects to WiFi but does not control it. You must log into the router itself through a web browser or app. Some internet providers offer an app that lets you change the WiFi password remotely, so check if your provider has one available.

What should I do if I forgot my new WiFi password?

Log back into your router's settings page using the admin password, find the WiFi password field, and look at what is stored there. You can also change it to something new if you want. If you forgot the admin password too, you will need to factory reset the router.

Why does my iPhone keep asking for the WiFi password even after I entered it?

This usually means you typed the password incorrectly. Tap "Forget This Network" in WiFi Settings, then reconnect and type the password more carefully. Make sure Caps Lock is off unless your password actually has capital letters. If it keeps failing, log into the router and verify the password you set is what you think it is.
