How to change your CenturyLink WiFi password

Creating a unique password is an important step in securing your home network. There are three ways you can change your WiFi password:

  1. In the CenturyLink app (for some modem models)
  2. On the My CenturyLink website
  3. From your secure modem settings, which you can access on a computer or other connected device


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

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.

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.
