How to Change Your Wi-Fi Password (on Any Router, and in Your ISP's App)

Learning how to change your Wi-Fi password is one of the fastest security wins in your home: the whole job takes under three minutes on most routers, and it is the single move that locks out everyone who should no longer be on your network. You log in to your router's admin page, open the wireless settings, type a new password, and save — then every device reconnects with the new one. This guide walks the two ways to do it: the router admin page for a router you own, and your internet provider's app for a rented gateway. It also clears up the confusion that trips up most people before they even start: your Wi-Fi password and your router's admin password are two different passwords.

Before you type anything, pick a strong new password first — a password generator makes a long random passphrase in seconds, which is exactly what a Wi-Fi password should be. And if you are here because you cannot remember the current password at all, start by reading how to find your Wi-Fi password — you may not need to change anything yet. Once the new password is set, you can share a Wi-Fi password with a QR code instead of spelling it out letter by letter.

How do I change my Wi-Fi password?

To change your Wi-Fi password, log in to your router's admin page in a web browser — usually at 192.168.0.1 or 192.168.1.1 — open the Wireless or Wi-Fi settings, type a new password of at least 12 characters into the password field, and save. Every device on the network disconnects at that moment and must reconnect with the new password.

1. Connect to your network. Use a computer or phone already on the Wi-Fi, or plug in with an Ethernet cable — the cable is the safer choice, because the device you are using will drop off the Wi-Fi the moment you save.
2. Open the router's admin page. Type the router's IP address into your browser's address bar. The usual addresses are 192.168.0.1 or 192.168.1.1; the exact one is printed on the sticker on the bottom or back of the router.
3. Log in with the admin credentials. These are the router's own username and password, printed on the same sticker — not your Wi-Fi password. If they were never changed, they are the factory defaults for your model.
4. Open Wireless or Wi-Fi settings. Look for a menu item labeled Wireless, Wi-Fi, WLAN, or Wireless Security.
5. Type the new password. Find the field labeled Wi-Fi Password, Network Key, Passphrase, or WPA Pre-Shared Key and enter the new password. On a dual-band router, set the same password for the 2.4 GHz and 5 GHz bands unless you deliberately run separate networks.
6. Save and reconnect everything. Click Save or Apply. The router applies the change within seconds, and every device on the network drops off until you re-enter the new password on each one.

First, the two passwords: your Wi-Fi password is not your admin password

Your router has two different passwords, and mixing them up is the most common reason people get stuck before they start. The Wi-Fi password — also called the network key or passphrase — is the password devices type to join your wireless network. The admin password is the password you type to open the router's own settings page, and it protects every setting on the router, including the Wi-Fi password itself. This guide changes the Wi-Fi password; if you cannot log in to the admin page at all, the troubleshooting section at the end covers that separately.

Keep the two passwords different from each other, and change the admin password too if it is still the factory default printed on the sticker. A stranger who can guess the default admin login can change any setting on your network, including the Wi-Fi password you just set. The network name, or SSID, is a third thing entirely: it is the name your devices see in the Wi-Fi list, and changing the password does not change it.

How do I find my router's IP address?

Your router's IP address is the address you type into a browser to reach its settings page, and for most home routers it is 192.168.1.1 or 192.168.0.1. The fastest way to find it is the sticker on the bottom or back of the router, which lists the default IP address, username, and password together. Some brands also give you a shortcut address: TP-Link routers answer at tplinkwifi.net, and D-Link routers at dlinkrouter.local.

If neither default address loads the login page, the router may be using a different address. On Windows, open Command Prompt, run ipconfig, and look for the Default Gateway address — that is your router. The address can also differ when the router was set up by your internet provider, so the sticker is the authority: if the address on the label does not work, try a wired Ethernet connection, and check that you are not on a mobile hotspot or a VPN, which can silently move you off the router's network.

Where is the Wi-Fi password setting on my router brand?

Every router hides the setting in the same place — the wireless security section of the admin panel or the brand's mobile app — but the menu names differ by brand and firmware. The table below gives the shortcut for the five most common brands, taken from each maker's own support documentation.

Other brands follow the same pattern: log in at the router's IP, open the Wireless or WLAN settings, and edit the WPA key. If your router's interface was customized by your internet provider, or the menus above do not match what you see, use your provider's app instead — the next section covers that route.

How do I change my Wi-Fi password in my ISP's app?

If you rent your gateway from your internet provider, change the Wi-Fi password in the provider's app instead of the router's admin page. The rented gateway is managed by the provider, so its app is the supported route, and changes sync automatically. Xfinity, Verizon, and Cox all support changing the Wi-Fi password in their apps.

In the Xfinity app, sign in, select Connect, then Wi-Fi, choose your network, and tap Edit to update the name and password. In My Verizon, sign in, choose Internet, select your network, and edit the Wi-Fi name or password. In the Cox app, open the Panoramic Wifi settings and edit the Wi-Fi network name and password there. D-Link owners with a registered router can use the mydlink web portal instead: sign in at mydlink.com, choose the router from My Devices, go to Settings, then Basic Settings, expand the wireless band, and enter the new password — the router takes at least 80 seconds to save the changes and reboot. Rogers customers on a Hitron modem follow the same admin-page pattern through a browser at 192.168.0.1, signing in with the credentials on the modem's white sticker and changing the password under the Wireless menu.

What makes a strong Wi-Fi password?

A strong Wi-Fi password is long first and complicated second. Current guidance from NIST, in SP 800-63B, requires passwords used on their own to be a minimum of 15 characters, and favors length over complexity — a passphrase built from several random words beats a short password full of symbols, and it is easier to type on a TV remote too. TP-Link's own guide recommends at least 12 to 16 characters, mixing uppercase and lowercase letters, numbers, and symbols, and avoiding names, birthdays, addresses, or the word "password."

The security mode matters as much as the password itself. Check the setting in the same wireless security section where you change the password, and pick the strongest option your devices support.

What happens to my devices after I change the password?

Every device on the network drops offline the moment the password changes — including the device you used to make the change, which is why an Ethernet cable or a ready reconnect plan matters. Phones and laptops show an "incorrect password" message until you forget the network and rejoin with the new password. Smart TVs, printers, cameras, and smart-home hubs need their Wi-Fi settings updated individually, usually through their own setup apps, which prompt you on the next launch.

Tell everyone in the household the new password before you save the change, so nobody is locked out mid-task. If your internet feels slow after the change, it is worth checking whether the problem was the network or the password: run a test to check your internet speed, and if the connection itself is the problem, these steps to speed up your Wi-Fi start with the router settings you have just opened.

When should I change my Wi-Fi password?

Change your Wi-Fi password when there is a reason, not on a calendar. Current NIST guidance no longer recommends forced periodic changes without evidence of a problem — length and WPA2 or WPA3 protection do more for security than scheduled rotation. The reasons that actually call for a change are concrete: you shared the password with a guest or a former housemate who should no longer have access, a device was lost or sold, you spot an unfamiliar device in your router's connected-devices list, or the password is still the factory default printed on the sticker.

Other good moments are moving into a new home, setting up a new router, or noticing the network is slower than usual without explanation — removing unknown connections often restores the speed. TP-Link still suggests changing the password every three to six months as a habit for home networks, and monthly for a home office handling client data, so if a routine suits you, that interval is a reasonable one. Either way, review the connected-devices list in your admin panel after the change and remove anything you do not recognize.

What if I forgot my router's admin password?

If you cannot log in to the admin page, the Wi-Fi password cannot be changed from the settings — but you are not stuck. First, try connecting with an Ethernet cable, which works even when the Wi-Fi password is forgotten. Then try the credentials printed on the router's sticker; on many routers the default is a username of admin with a unique code or a blank password field, depending on the model.

If nothing works, the last resort is a factory reset: press the small recessed reset button on the back of the router — usually with a pin — and hold it for about 10 seconds. The reset restores the factory defaults, so the admin login returns to the sticker credentials, but it also erases your Wi-Fi name and password and every other setting, and you will have to set the network up again from scratch. Photograph your current settings first if you can still reach them, and only reset when you are ready to reconfigure the router.

Frequently asked questions

How often should I change my Wi-Fi password?

Change it when there is a reason — a guest moved out, a device was lost, an unknown device appears on your network, or the password is still the factory default. Current NIST guidance does not require calendar-based rotation. TP-Link still suggests every three to six months as a habit for home networks.

Will changing my Wi-Fi password make my internet faster?

Not directly. A new password changes who can join, not the line speed. If strangers were using your bandwidth, removing them frees it up and the connection can feel faster — but if the speed problem remains, it comes from your plan, your hardware, or the router's placement.

Can I change my Wi-Fi password from my phone?

Yes. Log in to the router's admin page in a mobile browser, or use the brand app — TP-Link Tether, NETGEAR Nighthawk, the ASUS Router app, or the eero app. Your internet provider's app works too: Xfinity, My Verizon, and the Cox app all support it.

What do I do if I forget the new password I just set?

Log back into the admin panel from a device that is still connected and view or change the password again. If no device is connected and you cannot reach the admin page, use the recessed reset button on the back of the router to restore factory settings, then set a new password from scratch.

Do I need to change the password for 2.4 GHz and 5 GHz separately?

Only if your router runs separate network names per band. Most modern routers default to one unified name, and when bands are unified, one password covers all of them. D-Link's guide notes the two bands can have different passwords if you set them that way.
