Where to find your Xfinity username and password
Your Xfinity username and password are stored in your account, and Comcast gives you three ways to retrieve them without calling support. The fastest is the Xfinity website itself — you can reset your password in seconds if you have access to the email address on file. If you have already forgotten both, you can use your account number or phone number to verify your identity and get back in. If you are locked out completely, calling Xfinity at 1-800-934-6489 will get you a temporary password by phone.
Your username is almost always the email address you used when you set up your account, though some older accounts use a custom username instead. Your password is something only you know — Xfinity does not display it anywhere for security reasons, so you will need to reset it if you have lost it.
Key Takeaways
- Your Xfinity username is the email address you registered with, unless you created a custom username before 2015.
- You can reset your password on the Xfinity website by entering your email and answering security questions or using a code sent to your email.
- If you do not remember your email address, use your account number or the phone number on your bill to verify your identity instead.
- Calling 1-800-934-6489 will give you a temporary password over the phone if the website reset does not work.
Reset your password on the Xfinity website
Go to xfinity.com and click "Sign In" in the top right corner. Below the password field, click "Forgot password?" and enter the email address associated with your account. Xfinity will send a reset link to that email — click it and follow the prompts to create a new password.
If you do not have access to that email address anymore, click "I don't have access to this email" on the same page. Xfinity will ask you to enter your account number or the phone number on your bill, then answer security questions you set up when you created your account. Once you verify your identity, you can set a new password when ready.
Find your account number if you need it
Your account number appears on your Xfinity bill, usually in the top right corner or under your name. If you do not have a recent bill, log into your account on xfinity.com (if you can), go to "Account" in the top menu, and select "Billing." Your account number will be displayed there.
You can also find your account number by calling 1-800-934-6489 and providing your name and the phone number associated with your account. The automated system will read it back to you, or you can stay on the line to speak with a representative.
What to do if security questions do not work
If you cannot remember the answers to your security questions, or if you set them up so long ago that you no longer have access to the information you used, you have two options. First, try the email reset method again — if you still have access to your registered email address, that is the fastest way through.
If neither works, call 1-800-934-6489 and tell the representative you need a password reset. They will verify your identity using information from your account — usually your name, address, and account number — then send a temporary password to your email or read one to you over the phone. You can change this temporary password to something permanent as soon as you log in.
Recover a custom username from before 2015
If your account is older and you created a custom username (not an email address), you can find it by going to xfinity.com and clicking "Sign In." Below the username field, click "Forgot username?" and enter the email address or phone number on your account. Xfinity will display your username or send it to your email.
Custom usernames are less common now because Xfinity switched to email-based accounts years ago. If you have an older account and cannot remember your custom username, the phone reset method will work — call 1-800-934-6489 and ask them to confirm your username before you reset your password.
Use the Xfinity mobile app if the website is down
If the Xfinity website is unavailable, you can still reset your password using the Xfinity mobile app on your phone. Open the app, tap "Sign In," then tap "Forgot password?" and follow the same steps as the website — enter your email, verify your identity, and set a new password.
The app uses the same account system as the website, so if you can reset your password there, you can when ready use it to log in on any device. If the app is also not working, call 1-800-934-6489 for a phone-based reset.
What happens after you reset your password
Once you create a new password, you can log into xfinity.com or the Xfinity app right away. Your new password takes effect when ready — any old sessions will be logged out for security. Write down your new password somewhere safe, or use a password manager to store it so you do not lose it again.
If you reset your password but still cannot log in, clear your browser's cache and cookies, then try again. If that does not work, call 1-800-934-6489 and let them know the reset did not work — they can check for account issues that might be blocking your access.
Frequently Asked Questions
Can I change my username to something other than my email?
No. Xfinity stopped allowing custom usernames years ago and now requires all accounts to use an email address as the username. If you have an older custom username, you can still use it to log in, but you cannot change it to a new one. You can change the email address on your account, which will become your new username.
What if I do not remember the email address I used to sign up?
Use your account number or the phone number on your bill instead. Go to xfinity.com, click "Forgot password?", then click "I don't have access to this email." Enter your account number or phone number and answer your security questions. Once verified, you can reset your password and log in.
How long does a temporary password last?
A temporary password given to you over the phone works when ready and lasts until you log in and change it to a permanent one. Once you log in with the temporary password, you will be prompted to create a new password before you can access your account.
Can I reset my password without a phone number or account number?
If you have access to the email address registered on your account, yes — that is the only thing you need. If you do not have access to that email, phone number, or account number, call 1-800-934-6489 and speak with a representative. They can verify your identity using your name and address.
Is my Xfinity username the same as my email username?
Your Xfinity username is the full email address you registered with, not just the part before the @ symbol. For example, if you signed up with jane.smith@gmail.com, your Xfinity username is jane.smith@gmail.com, not jane.smith.
