Your PPPoE credentials are login information your internet service provider gives you to connect to their network

A PPPoE username and password are the credentials your ISP uses to verify that you are the account holder and that you have paid for internet service. When your modem or router connects to the internet, it sends these credentials to your ISP's server. The server checks them, and if they match, it allows your connection through. Without them, your modem cannot establish a connection at all — it is how the ISP knows it is you on the other end of the line.

These are different from your WiFi password. Your WiFi password protects your home network from neighbours and strangers. Your PPPoE credentials protect your ISP account from someone else claiming to be you and using your service. One is about your local network; the other is about your account with the company.

Most people never see or type these credentials after the initial setup. Your modem or router stores them and sends them automatically every time it connects. But if you move, switch providers, reset your equipment, or troubleshoot a connection problem, you may need to find them or enter them again.

Key Takeaways

  • PPPoE username and password are account credentials your ISP uses to verify you are a paying customer, not WiFi login information.
  • Your modem or router stores these credentials and sends them automatically, so you typically do not type them after setup.
  • You can find these credentials on your ISP's billing statement, in your account portal online, or by calling customer service.
  • If you reset your modem or move to a new location, you will need to re-enter these credentials into your equipment.
  • Changing your PPPoE password through your ISP's account portal will disconnect your current connection until you update your modem or router.

Where to find your PPPoE username and password

Your ISP sends this information to you when you first sign up for service. Check your welcome email, welcome packet, or the paperwork that came with your modem. Many ISPs print the PPPoE username and password on a sticker attached to the modem itself or on a card inside the box.

If you cannot find the original paperwork, log into your ISP's account portal on their website. Most providers have a section for account settings, service details, or equipment information where you can view or reset your PPPoE password. The exact location varies by provider — Comcast calls it one thing, Verizon another — but customer service can point you to the right page in about one minute.

If you do not remember your account login for the ISP's website, call customer service. They can verify your identity using your account number, phone number, or the last four digits of the card on file, then either tell you the credentials or send them to you by email.

What happens when you change your PPPoE password

If you change your PPPoE password through your ISP's account portal, your modem or router will when ready lose its connection. The old password no longer works, so the ISP rejects the next connection attempt. Your internet will drop, and you will see no connection until you update the credentials in your equipment.

To restore the connection, you need to log into your modem or router's settings page (usually at 192.168.1.1 or 192.168.0.1 in your browser) and enter the new PPPoE password. Once you save the change, the modem will reconnect within a few seconds. This is why you should only change your PPPoE password when you are home and can update your equipment right away.

If you change the password and then cannot remember the new one, you can reset it again through your ISP's account portal or by calling customer service. There is no penalty for changing it multiple times.

When you need to re-enter PPPoE credentials

You will need to enter your PPPoE username and password into your modem or router in a few common situations. If you reset your modem to factory settings, all stored credentials are erased, and you must enter them again. If you replace your modem with a new one, the new equipment has no stored credentials. If you move to a new address and your ISP sends you a new modem, that equipment will also need the credentials entered.

Some ISPs automatically provision new modems with your account credentials before they ship them to you, so they connect when ready when you plug them in. Others require you to enter the credentials manually. Your ISP's setup guide or customer service can tell you which applies to your situation.

The difference between PPPoE credentials and other passwords

Your PPPoE username and password are separate from your WiFi password, your ISP account login, and any other password associated with your service. Your WiFi password is what guests and family members use to connect their phones and laptops to your home network. Your ISP account login is what you use to view your bill and manage your account online. Your PPPoE credentials are what your modem uses to authenticate with the ISP's network.

Some ISPs set all of these to the same value by default, which can be confusing. But they serve different purposes and can be changed independently. Changing your WiFi password does not affect your PPPoE credentials, and changing your PPPoE password does not affect your WiFi password.

Troubleshooting a PPPoE connection problem

If your modem shows a PPPoE error or cannot connect, the most common cause is an incorrect username or password stored in the modem. Check that you have entered the credentials exactly as your ISP provided them — PPPoE usernames are often case-sensitive, and spaces or special characters matter. If you are not sure, reset the credentials in your modem's settings page and re-enter them carefully.

The second most common cause is that your ISP's PPPoE server is temporarily down. This is rare but does happen during maintenance. If you have confirmed the credentials are correct, restart your modem by unplugging it for 30 seconds, then plugging it back in. If the connection still does not restore within a few minutes, contact your ISP's customer service to check whether there is a known outage.

If you have changed your PPPoE password recently and forgot to update your modem, the connection will fail with an authentication error. Log into your modem's settings page and enter the new password. The connection should restore when ready.

Keeping your PPPoE credentials find

Your PPPoE username and password should be treated like any other account credential. Do not share them with anyone except a technician from your ISP who is helping you troubleshoot a problem. Do not write them down and leave them in a visible place. If you suspect someone else knows your credentials, contact your ISP and change your PPPoE password.

If you are selling or giving away your modem, reset it to factory settings first. This erases all stored credentials, including the PPPoE password. A factory reset removes your WiFi settings, PPPoE credentials, and any other configuration, returning the modem to its original state.

Frequently Asked Questions

Is my PPPoE username the same as my email address?

Not always. Some ISPs use email addresses as PPPoE usernames, but others use account numbers, phone numbers, or custom usernames. Check your welcome materials or account portal to see what your ISP assigned to you. If you are unsure, customer service can confirm it in seconds.

Can I change my PPPoE username?

Most ISPs do not allow you to change your PPPoE username because it is tied to your account number in their system. You can change your PPPoE password, but the username is usually fixed. If you want a different username, contact your ISP to ask whether they offer that option.

What if I enter the wrong PPPoE password too many times?

Your modem will keep trying to connect and will fail each time, but your account will not lock. There is no limit to how many times you can attempt to connect with the wrong password. However, repeated failed attempts may trigger a temporary slowdown or block from your ISP's server as a security measure. If this happens, wait a few minutes and try again with the correct password.

Do I need to know my PPPoE credentials to use the internet?

No. Once your modem or router is set up and connected, it stores the credentials and handles authentication automatically. You will not need to type them in or think about them unless you reset your equipment, move, or troubleshoot a connection problem.

Can my ISP see my PPPoE password?

Yes. Your ISP stores the password in their system and uses it to verify your connection. They can reset it or change it on your behalf if you call customer service. This is normal and expected — the password is part of your account with them, not a secret you keep from them.
