Where to log in to your United Explorer Card account
The United Explorer Card is issued by Chase, so you log in through Chase's website or mobile app, not through United Airlines directly. Go to chase.com, select "Credit Cards" from the menu, then look for the sign-in option. You can also read the Chase Mobile app from your phone's app store and log in there.
Your username is typically the email address you registered with Chase when you opened the card. If you have other Chase accounts (checking, savings, or other credit cards), you use the same login credentials for all of them. Once you're signed in, your United Explorer Card appears alongside any other Chase accounts you hold.
The card itself will have a 16-digit number on the front. You do not need this number to log in — only your username (email) and password. If you've never set up online access before, you'll need to create a Chase account first, which takes about five minutes.
Key Takeaways
- Log in at chase.com or through the Chase Mobile app using your email address and password, not through United's website.
- Your United Explorer Card account is part of your overall Chase account, so one login covers all your Chase products.
- If you forget your password, use the "Forgot password?" link on the login page to reset it by email or phone verification.
- Two-factor authentication (a code sent to your phone or email) adds security and is turned on by default for most accounts.
What you can do once you're logged in
After logging in, you can view your current balance, recent transactions, and available credit. You can also pay your bill, set up automatic payments, and read statements. The account page shows your rewards balance (called "Ultimate Rewards points" on the Explorer Card) and lets you see how many points you've earned from purchases and sign-up bonuses.
You can also update your contact information, change your password, set spending alerts, and report the card lost or stolen. If you want to redeem your points for travel or other rewards, you do that through the rewards section of your Chase account, not through United's site.
Resetting your password if you're locked out
If you forget your password, click "Forgot password?" on the Chase login page. Chase will ask you to verify your identity using either your email address or a phone number on file. You'll receive a code (usually within seconds) that you enter to confirm it's really you.
After verification, you'll be taken to a page where you create a new password. Chase requires passwords to be at least 8 characters long and to include uppercase letters, lowercase letters, and numbers. Once you've set your new password, you can log in when ready with it.
Two-factor authentication and security
Chase uses two-factor authentication to protect your account, which means you need something you know (your password) and something you have (your phone or email). When you log in from a new device or location, Chase sends a code to your phone or email. You enter this code on the login page to finish signing in.
You can choose whether to receive codes by text message or email. If you don't have a phone number on file, you can add one in your account settings. The code expires after a few minutes, so you'll need to enter it quickly. This extra step takes about 30 seconds but makes it much harder for someone else to access your account even if they know your password.
Logging in on your phone versus a computer
The Chase Mobile app and the website show the same information and let you do the same tasks. Many people find the app faster for checking their balance or making a quick payment, while the website works better for detailed tasks like downloading multiple statements or reviewing a long transaction history.
If you use the app, you can set it to remember your login on that specific phone, which means you won't have to enter your password every time. However, if your phone is lost or stolen, you should log out remotely through your Chase account settings or call Chase to lock your account. The app also lets you turn on biometric login (fingerprint or face recognition) for faster access without typing your password.
What to do if you can't log in
If you've reset your password and still can't log in, the problem might be that your account is locked for security reasons. This can happen if Chase detects unusual activity or if you enter the wrong password too many times. Call the customer service number on the back of your United Explorer Card — Chase's fraud team can unlock your account and verify your identity over the phone.
If you never created a Chase online account in the first place, you'll need to set one up first. Go to chase.com, click "Enroll now" or "Create account," and follow the steps. You'll need your card number, Social Security number, and date of birth. If you don't have your card handy, you can still enroll using your Social Security number and date of birth, and Chase will look up your account.
Linking your United Airlines account to your Chase account
Your United Explorer Card and your United Airlines frequent flyer account are separate. You can link them in your United account settings so that purchases on the card automatically post to your frequent flyer account. However, you don't need to link them to log into your card — that's done through Chase only.
To link the accounts, log into your United Airlines account (at united.com), go to your profile settings, and look for the option to add a credit card or link a Chase account. You'll enter your card number or authorize the connection. Once linked, your points and miles will show up in both places, and you can track them more easily.
Frequently Asked Questions
Can I log into my United Explorer Card through United's website?
No. The United Explorer Card is a Chase product, so you log in at chase.com or through the Chase Mobile app. United's website does not have a login for credit card accounts. You can link your card to your United frequent flyer account separately, but that's different from logging into the card itself.
What do I do if I never received a confirmation email after signing up for Chase online?
Check your spam or junk folder — confirmation emails sometimes end up there. If you still don't see it, call the number on the back of your card and ask Chase to resend the confirmation. You may also be able to log in when ready without waiting for the email, depending on how you signed up.
Is it safe to log in to my Chase account on public Wi-Fi?
Chase's website uses encryption, so your login information is protected even on public Wi-Fi. However, using your own phone data or a home network is safer. If you do log in on public Wi-Fi, make sure you log out completely when you're done, and avoid using public computers if possible.
Can I change my login email address?
Yes. Log into your Chase account, go to "Profile & Settings," then "Contact Information," and update your email address. Chase will send a confirmation to your new email. You'll use the new email address the next time you log in.
What happens if I forget my username?
Your Chase username is the email address you registered with. If you're not sure which email you used, click "Forgot username?" on the login page. Chase will ask you to verify your identity and then show you the email address on file. If that email is no longer active, call the number on your card to update it.
