Check your welcome packet or setup email first
Your ISP username and password are usually in the paperwork that arrived when you signed up for service. Look for a welcome letter, setup guide, or card that came in the mail — it often has a section labeled "Account Information" or "Login Credentials" with both pieces printed clearly.
If you signed up online, check the email address you used during registration. Most ISPs send a confirmation email within hours that includes your username and a temporary password. Search your inbox and spam folder for emails from your ISP's domain name — for example, if you use Comcast, search for messages from @comcast.com or @xfinity.com.
The username is usually your account number, your email address, or a custom name you created during setup. The password may be temporary and require you to change it on first login.
Key Takeaways
- Your ISP username and password appear in your welcome packet, setup email, or account confirmation message sent when you first signed up.
- If you cannot find the original documents, log into your ISP's customer portal using your account number or email address to reset your password.
- Your ISP's customer service phone number is on your monthly bill or on their website, and they can verify your identity and send credentials to you.
- Never share your ISP username and password with anyone except a technician you called directly, and change your password if you think someone else knows it.
Log into your ISP's online account portal
If you cannot locate your original paperwork, go to your ISP's website and look for a "Log In" or "My Account" button. Most major ISPs have a customer portal where you can view your account details, including your username.
Click "Forgot Password" or "Forgot Username" on the login page. You will be asked to verify your identity — usually by entering your account number (found on your bill), your phone number, or your email address. Once verified, the ISP will either display your username or send a password reset link to your email.
Common ISP portals include Xfinity (Comcast), Verizon Fios, AT&T, Charter Spectrum, Cox, and CenturyLink. If you are unsure which ISP you use, check your monthly internet bill — the company name and customer service number are printed at the top.
Call your ISP's customer service line
If the online portal does not work or you prefer to speak with someone, call the customer service number on your bill. Have your account number and a form of ID ready — the representative will ask for these to verify you are the account holder.
Tell them you need your PPPoE username and password. They can look up both in your account and either read them to you over the phone or email them to your registered email address. This process usually takes a few minutes.
Customer service lines are typically open during business hours, though many ISPs now offer 24/7 support. If you are calling during off-hours, you may be able to use an automated system or chat feature on the ISP's website instead.
Check your modem or router for stored credentials
If you have already connected to the internet using PPPoE, your modem or router may have the username and password stored in its settings. This works only if you set up the connection yourself and the device is still powered on.
Log into your modem's admin panel by opening a web browser and typing your modem's IP address (usually 192.168.1.1 or 192.168.0.1). You will need the modem's admin username and password — these are often printed on a sticker on the back of the device and are different from your ISP credentials.
Once logged in, look for a section called "WAN Settings," "Internet Settings," or "PPPoE." The ISP username and password may be displayed there, though some modems hide the password for security. If you see only asterisks or dots, you will need to use one of the other methods above.
What to do if you cannot remember your account number
Your account number appears on your monthly bill, in your welcome packet, and in any service confirmation emails. If you have lost all of these, you can still contact your ISP by phone or through their website using your phone number or email address instead.
When you call, explain that you do not have your account number handy. The representative can look up your account using your name, phone number, and service address. This verification step takes a bit longer but is a normal part of the process.
Keep your credentials find after you find them
Once you have your username and password, write them down and store them somewhere safe — a locked drawer, a password manager, or a find note app. Do not email them to yourself or leave them in an unsecured document.
Never share your ISP username and password with anyone except a technician you called directly from your ISP's official phone number. If a technician arrives at your home without you calling first, ask to see their ID and verify their employment by calling your ISP's main number before giving them any credentials.
If you think someone else has learned your password, log into your ISP's account portal and change it when ready. Most ISPs allow you to set a new password without calling customer service.
Frequently Asked Questions
Is my ISP username the same as my email username?
Not always. Some ISPs use your email address as your username, but others assign a separate account number or username. Check your welcome packet or account portal to see which one your ISP uses for PPPoE login.
What if my ISP says they cannot find my account?
Make sure you are providing the correct service address and phone number. If you recently moved or changed your phone number, tell the representative. If the account truly cannot be found, you may need to set up a new account or contact the billing department.
Can I change my ISP username and password myself?
Most ISPs allow you to change your password through their online account portal. Your username is usually tied to your account and cannot be changed, but you can contact customer service if you need a different one assigned.
What if I set up PPPoE but forgot to save the credentials?
Log into your modem's admin panel and check the WAN or PPPoE settings — the credentials may still be stored there. If not, use your ISP's online portal or call customer service to have them resent to your email.
Do I need my ISP password for everyday internet use?
No. You only need your ISP username and password when you first set up PPPoE on a modem or router, or if you need to change your connection settings. For normal browsing, you use your Wi-Fi password instead.
