How to change your CenturyLink WiFi password

Creating a strong password (also called a network security key) is an important step in securing your home network.

Unable to edit your network?

There are some scenarios where you can't change your WiFi password in My CenturyLink. Learn more about these special cases.


There are also times when the connection between our network and your modem temporarily won't allow you to edit your network. If this happens, you won't see the Edit Network option. You can try again later, or do it from your modem settings.

There are three ways you can change your WiFi password:

  1. In the CenturyLink app
  2. On the My CenturyLink website
  3. From your modem settings


While you're securing your network, you may also want to customize your network name (SSID).

How to change your WiFi password in the CenturyLink app

If you have one of our newer modems, the My CenturyLink app is the easiest way to change your WiFi password.

1. Go to the My Services screen from the menu at the bottom of the app, then scroll down the screen to find your list of WiFi networks. Tap on the network whose password you want to change.

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 contain:

  • Between 8 and 63 characters

  • At least one number from 0 to 9

  • 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 sign back in to the Wireless Security menu and choose "Use Default." This will revert the password to the original one printed on the modem sticker.
