Where to find your CenturyLink login information

Your CenturyLink username and password are usually in the welcome email you received when you first signed up for service. Check your email inbox — including spam and promotions folders — for a message from CenturyLink or Lumen (the parent company). That email typically contains your account username, a temporary password, and a link to set up your permanent password.

If you cannot find the welcome email, your username and password information may also appear on your first paper bill or in your online account portal if you can still access it. Some customers use their phone number or email address as their username instead of a separate account name, so try those first before resetting.

Key Takeaways

  • Your original CenturyLink username and password were sent in a welcome email when your account was created, usually found in your inbox or spam folder.
  • You can reset your password through the CenturyLink website without needing your old password, using your account number or phone number.
  • Your username is often your phone number or email address rather than a custom account name.
  • If you do not have your account number, you can look it up using your phone number or the service address on file.

How to reset your password if you have forgotten it

Go to the CenturyLink login page at centurylink.com and click "Forgot Password?" or "Forgot Username?" depending on what you need. You will be asked to enter either your account number, phone number, or the service address associated with your account. CenturyLink will then send a password reset link to the email address on file.

Click the link in that email and create a new password. Your new password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a special character like ! or @. Once you set it, you can log in when ready with your username and new password.

Finding your account number to reset your login

Your account number appears on every CenturyLink bill, usually in the upper right corner or near your name and service address. If you do not have a recent bill, you can find your account number by calling CenturyLink customer service at 1-800-CENTURYLINK (1-800-236-8879) and providing your phone number or service address.

You can also log into your account using your phone number as the username if you remember the password. Many CenturyLink customers set up their account with their phone number as the login username by default, so this is often faster than hunting for a separate account name.

What to do if you cannot access the email address on file

If the email address linked to your CenturyLink account is no longer active or you no longer have access to it, you will need to contact CenturyLink directly to update it. Call 1-800-CENTURYLINK and have your account number, phone number, and service address ready. A representative can verify your identity and change the email address on your account so you can receive password reset links.

Once the email is updated, you can use the "Forgot Password?" option on the website to reset your login. This usually takes a few minutes to process, and you should receive the reset email within a few minutes after requesting it.

Logging in to your CenturyLink account online

After you have your username and password, go to centurylink.com and click "Sign In" in the upper right corner. Enter your username (usually your phone number or email address) and your password. If you have multiple accounts with CenturyLink, you may be asked to select which account you want to access.

Once logged in, you can view your bill, make payments, check your data usage, manage your services, and update your contact information. If you want to stay logged in on that device, check the "Remember Me" box — but only do this on a personal computer, not on a shared or public device.

Saving your login information securely

Write down your username and password in a physical notebook kept in a safe place, or store them in a password manager like Bitwarden, 1Password, or KeePass. Password managers encrypt your login details and fill them in automatically when you visit the CenturyLink website, so you do not have to type them each time.

Do not save your password in a browser's built-in password storage if you share the computer with others, and never write it on a sticky note left near your desk. If you use a password manager, make sure the master password is something only you know and that you store it somewhere safe.

Frequently Asked Questions

Can I use my email address as my CenturyLink username?

Yes. Many CenturyLink accounts use the email address on file as the login username. Try logging in with your email address first. If that does not work, your username is likely your phone number or a custom account name from when you signed up.

What if I get an error message saying my username or password is wrong?

Passwords are case-sensitive, so make sure Caps Lock is off. If you still cannot log in, use the "Forgot Password?" link to reset it. If you are unsure of your username, use "Forgot Username?" and enter your account number or phone number instead.

How long does it take to receive a password reset email from CenturyLink?

The reset email usually arrives within a few minutes. Check your spam and promotions folders if you do not see it in your inbox within 10 minutes. If it does not arrive, try requesting the reset again or contact CenturyLink customer service.

Can I change my username after I set up my account?

CenturyLink does not allow you to change your username once the account is created. If you want a different login name, you would need to contact customer service to discuss your options, though they may not be able to change it.
