The fastest way to change your password

Log into your router's admin panel by opening a web browser, typing your router's IP address (usually 192.168.1.1 or 192.168.0.1), and entering your admin username and password. Look for a section called "Wireless," "WiFi," or "Security Settings," find the field labeled "WiFi Password" or "Pre-Shared Key," enter your new password, and click Save or explore. Your router will restart, and all devices will disconnect — you'll need to reconnect using the new password.

The whole process takes about five minutes. If you don't know your router's IP address or admin password, check the sticker on the back of the router or the paperwork that came with it. If you've changed the admin password before and forgotten it, you'll need to factory reset the router, which erases all your settings.

Key Takeaways

  • Your router's IP address is usually printed on a sticker on the back of the device or in your setup paperwork.
  • The default admin username and password are also on that sticker — change them from the defaults if you haven't already.
  • WiFi passwords must be at least 8 characters long and are case-sensitive, so write down what you choose before you save it.
  • All your devices will disconnect when the router restarts, and you'll need to reconnect each one with the new password.
  • If you've forgotten your admin password, a factory reset is the only way back in, but it wipes all your custom settings.

Finding your router's login information

Every router has a physical sticker on the back or bottom that shows the default IP address, username, and password. The IP address is usually 192.168.1.1, 192.168.0.1, or 10.0.0.1. Write these down before you start.

If the sticker is worn or missing, check your router's manual or the box it came in. You can also search online for "[your router model] default IP address" — just make sure you're looking at the manufacturer's official documentation, not a random forum post. Common router brands include TP-Link, Netgear, Linksys, Asus, and Arris.

Logging into your router's admin panel

Open any web browser on a device connected to your WiFi. Type the IP address into the address bar exactly as it appears on the sticker — for example, type 192.168.1.1 and press Enter. A login page will appear asking for a username and password.

Enter the default username and password from the sticker. Most routers use "admin" as the username and "admin" or "password" as the password, but this varies by brand. If the defaults don't work, double-check the sticker or manual. Once you're logged in, you'll see a dashboard with various settings and menus.

Locating the WiFi password setting

Look for a menu labeled "Wireless," "WiFi," "Network," or "Security." Some routers organize this under "Advanced Settings" or "Wireless Settings." The exact location depends on your router's brand and model, but the option is always there somewhere.

Once you find the wireless settings, look for a field called "WiFi Password," "Pre-Shared Key," "Passphrase," or "Network Key." This is the password people use to connect to your network. Do not confuse it with the admin password, which is what you use to log into the router itself — those are two separate things.

Creating a strong new password and saving it

WiFi passwords must be at least 8 characters long. Use a mix of uppercase letters, lowercase letters, numbers, and symbols (like ! or #) to make it harder to guess. Avoid using your name, address, or anything that appears on the sticker. Write down the new password before you save it — once the router restarts, you'll need it to reconnect your devices.

Clear the old password field completely, type your new password into the field, and look for a button labeled "Save," "explore," or "OK." Click it. Your router will restart, which usually takes 30 seconds to two minutes. During this time, your WiFi will go offline and all connected devices will disconnect.

Reconnecting your devices after the restart

Once the router finishes restarting, your WiFi network name will reappear in the list of available networks on your phone, laptop, or tablet. Select it, choose "Connect," and enter your new password when prompted. Make sure you type it exactly as you wrote it down — passwords are case-sensitive, so "MyPassword123" is different from "mypassword123."

Repeat this process for every device that was connected to your WiFi: phones, tablets, laptops, smart speakers, security cameras, printers, and anything else. Devices won't automatically reconnect with the old password — you have to tell each one the new one. If a device doesn't reconnect after you enter the password, restart that device and try again.

What to do if you're locked out

If you've forgotten your admin password and can't log into the router, you'll need to perform a factory reset. Look for a small reset button on the back of the router, usually recessed so you need a paperclip or pen to press it. Hold it down for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart.

A factory reset erases all your settings — your WiFi password, admin password, port forwarding rules, and anything else you've customized. After the reset, the router returns to its default state, and you can log in again using the default credentials from the sticker. You'll then need to set up your WiFi password and admin password from scratch.

Frequently Asked Questions

Can I change my WiFi password from my phone instead of a computer?

Yes. Open a web browser on your phone, type your router's IP address into the address bar, and follow the same steps. Some router manufacturers also offer a mobile app that lets you change the password without typing the IP address, though the web browser method works on any phone.

What happens to devices that are currently connected when I change the password?

They will disconnect when the router restarts. You'll need to reconnect each device by selecting your WiFi network and entering the new password. Devices won't automatically reconnect — they'll stay disconnected until you manually enter the new password on each one.

Do I have to change my admin password too?

You should. The admin password protects access to your router's settings. If you leave it as the default, anyone who knows your router model can log in and change your WiFi password or other settings. Change it to something different from your WiFi password and write it down somewhere safe.

How often should I change my WiFi password?

There's no set schedule. Change it if you suspect someone unauthorized is using your network, if you've shared it with someone you no longer want to have access, or if you haven't changed it in several years. For most home networks, changing it once a year or when circumstances change is reasonable.

What if my router doesn't have a sticker with the default password?

Search online for your router's model number (printed on the device) plus "default password." Check the manufacturer's official website or support documentation. If you still can't find it, a factory reset is your only option — it returns the router to its default state so you can log in with the standard credentials.
