How to change your CenturyLink WiFi password

Creating a unique password is an important step in securing your home network. This article will show you two ways you can change your WiFi password:

  1. Through the CenturyLink App 
  2. Through the Wireless Security area of your modem settings, which you can access on a computer or other connected device

 

Note that you may also want to customize your network name (SSID) to make it easy to recognize.

The My CenturyLink app is the simplest way to change your WiFi password. In the app, go to the My Products screen. Your app will look different based on which modem you are using.

Is "Change My WiFi Password" not appearing on the app?

If this option isn't appearing in your app, here are a few things you can try:
 

  • Go to your app store, download any available updates on the CenturyLink app, then try again.

  • Check to make sure the modem is fully plugged in and getting power.

  • Use the "Test My Service" link within the app to run a troubleshooter that can check for network issues. 

  • Reboot the modem through the app or by manually unplugging it, waiting a full minute, and plugging it back in.

  • If rebooting doesn't work, call or chat to have a service agent help you further troubleshoot the issue.

NOTE:  Depending on your model, your modem's user interface may appear slightly different from the images below.

5.  If given a choice, select 2.4 GHz or 5 GHz. If you have both WiFi frequencies enabled, you should repeat steps 5-10 to change the WiFi password for both networks (you may use the same password for both if you want). Don't worry if you don't see the frequency options, as not all modems have this feature.

8.  Your Security Type is printed on the modem's sticker.
The Encryption Type should be set to "Both."
If prompted to give the Authentication Type, choose "Open."

Password tips

If you are prompted to choose 64 bits or 128 bits, follow these guidelines:

  • 64 bits: Enter 10 characters*
  • 128 bits: Enter 26 characters*
    * Characters can only contain letters between A-F and numbers between 0-9 with no spaces. 

In all other cases, your custom password must:

  • Be between 8 and 63 characters long
  • Contain at least one number from 0 to 9
  • Contain at least one letter from A to Z
    Note: The space character can be used (but is not required)

Helpful hint: If you lose or forget your password, you can always log back in to the Wireless Security menu and choose "Use Default" for the password. This will change it back to the original one printed on the modem sticker.
