Where to find your CenturyLink PPP login information

Your CenturyLink PPP username and password are usually printed on paperwork that came with your modem or router when you first set up your internet service. Look for a sticker on the back or bottom of the device itself — it often shows a default username (frequently "ppp") and a password that looks like a string of numbers and letters. If you cannot find the physical device or the sticker has worn away, CenturyLink customer service can retrieve this information by phone or through your online account.

PPP stands for Point-to-Point Protocol, and it is the connection method your modem uses to communicate with CenturyLink's network. This is different from your WiFi password, which protects your wireless network at home. You need the PPP credentials only if you are reconfiguring your modem or troubleshooting connection problems — most people never need to enter them after the initial setup.

Key Takeaways

  • Your PPP username and password are printed on a sticker attached to your CenturyLink modem or included in the paperwork that came with it.
  • The default PPP username is usually "ppp" and the password is a combination of numbers and letters specific to your device.
  • You can retrieve lost PPP credentials by calling CenturyLink customer service at 1-800-CENTURYLINK or logging into your account online.
  • PPP login information is separate from your WiFi password and is only needed when reconfiguring your modem or fixing connection issues.

Check the modem sticker first

Before contacting CenturyLink, physically inspect your modem. Turn off the device and look at the back panel and the bottom — most CenturyLink modems have a white or silver sticker with login details printed in small text. The sticker typically shows "Username" and "Password" labels with the actual credentials next to them. Write down exactly what you see, including capitalization and any special characters, because these details are case-sensitive.

If the sticker is faded or missing, check any paperwork that arrived with your modem — the original setup guide, welcome letter, or service agreement often includes this information. Keep this paperwork in a safe place for future reference. If you have moved or inherited the service from a previous customer, the original documentation may no longer be available, which means you will need to contact CenturyLink directly.

Retrieve credentials through your CenturyLink online account

Log into your CenturyLink account at centurylink.com using your email address and password. Once you are signed in, look for a section labeled "My Services," "Internet," or "Manage My Account." From there, find the option for "Modem Settings," "Device Information," or "Technical Support." Some accounts display the PPP username and password directly on this page; others require you to click through to a modem configuration page.

If you cannot find the information online, your account may not have this feature enabled. This is common with older accounts or certain service plans. In that case, move to contacting customer service — they can pull up your account details and provide the credentials over the phone or through email.

Call CenturyLink customer service for help

CenturyLink customer service can look up your PPP credentials in their system. Call 1-800-CENTURYLINK (1-800-236-8879) and have your account number or phone number ready. Tell the representative that you need your modem's PPP username and password. They will verify your identity and then read the credentials to you over the phone.

Wait times can be long during peak hours (typically 9 a.m. to 5 p.m. on weekdays). If you are in a hurry, try calling early morning or late evening. Some CenturyLink locations also offer chat support through their website, which may have shorter wait times than phone lines.

What to do if you cannot remember your password after finding it

If you have located your PPP credentials but cannot remember them after a few days, take a photo of the sticker or write the information in a password manager (like Bitwarden, 1Password, or the password manager built into your web browser). This way you have a backup copy without having to call customer service again.

If you have already changed your PPP password and no longer remember the new one, you will need to reset it. This typically requires logging into your modem's configuration page directly — you can do this by typing 192.168.0.1 or 192.168.100.1 into your web browser's address bar while connected to your CenturyLink internet. From there, look for "Advanced" or "Administration" settings. However, this step requires knowing at least one set of credentials to begin with, so contact CenturyLink if you are completely locked out.

Difference between PPP credentials and WiFi password

Your PPP username and password are not the same as your WiFi password. PPP credentials authenticate your modem to CenturyLink's network — they are used behind the scenes and you rarely need to enter them manually. Your WiFi password is what you use to connect your phone, laptop, or other devices to your home network wirelessly.

If you need to change your WiFi password, you can do that through your modem's settings page or through the CenturyLink app on your phone. If you need to change your PPP credentials, that is a more technical task that usually requires contacting CenturyLink or accessing the modem's advanced settings. For most home users, the PPP login information stays the same for the life of the modem.

Frequently Asked Questions

What if the sticker on my modem is completely worn off?

Call CenturyLink at 1-800-236-8879 with your account number or phone number. They can retrieve the original PPP credentials from their database. You can also try logging into your online account at centurylink.com, though not all accounts display this information there.

Is my PPP password the same as my CenturyLink account password?

No. Your CenturyLink account password is what you use to log into centurylink.com or manage your bill. Your PPP password is specific to your modem and is used for the connection between your device and CenturyLink's network. They are completely separate.

Do I need to know my PPP credentials to use the internet at home?

No. Once your modem is set up, the PPP credentials are stored in the device and used automatically. You only need them if you are reconfiguring the modem, replacing it, or troubleshooting a connection problem with CenturyLink support.

Can I change my PPP password myself?

Yes, but it requires accessing your modem's configuration page by typing 192.168.0.1 into a web browser. You will need to log in with your current PPP credentials first. If you are not comfortable doing this, CenturyLink support can change it for you over the phone.
