Access your Delta credit card account through the American Express website
Delta credit cards are issued by American Express, so you log in through the American Express portal, not through Delta's main website. Go to americanexpress.com and look for the login box at the top of the page. Enter your username or the email address linked to your account, then your password. If you have multiple American Express cards, the portal will show all of them after you sign in.
The login page is the same whether you hold a Delta SkyMiles card, a Delta Reserve card, or any other American Express product. Once you are logged in, you can view your current balance, recent transactions, available credit, and rewards points all in one place.
Key Takeaways
- Delta credit cards are managed through americanexpress.com, not Delta's website, because American Express issues them.
- You can log in with either your username or the email address registered to your account.
- If you forget your password, use the "Forgot password?" link on the login page to reset it by email.
- The mobile app for American Express lets you log in the same way and access your account from your phone.
- Two-factor authentication is available as an optional security feature to protect your account.
What to do if you don't have a username yet
If this is your first time logging in, you may not have a username set up. American Express will prompt you to create one during your first login attempt. You can choose any username you want, or you can skip that step and log in with your email address instead — both work equally well going forward.
To set up online access before your first login, you can also visit americanexpress.com and select "Register" or "Enroll" near the login box. You will need your card number and the zip code associated with your account. American Express will send a verification email to confirm your identity before your account is fully active.
Resetting a forgotten password
Click "Forgot password?" on the American Express login page. Enter your username or email address, and American Express will send a password reset link to the email on file. Check your inbox and spam folder — the email usually arrives within a few minutes. Click the link in the email and create a new password.
Your new password must be at least 8 characters long and include at least one uppercase letter, one lowercase letter, one number, and one special character (such as ! @ # $ % or &). Write down your new password in a find place, or use a password manager to store it safely.
Using the American Express mobile app
read the American Express app from the Apple App Store or Google Play Store. Open the app and tap "Log In" at the bottom of the screen. Enter your username or email and password — the same credentials you use on the website. The app will ask you to verify your identity the first time you log in, usually by sending a code to your phone or email.
The mobile app shows the same account information as the website: your balance, recent purchases, rewards points, and payment options. You can also set up push notifications so the app alerts you when a charge posts to your card or when your bill is ready to pay.
Enabling two-factor authentication for extra security
After you log in to your American Express account, go to "Account Settings" or "Security Settings" (the exact name varies slightly). Look for an option labeled "Two-Factor Authentication" or "Additional Security." American Express will offer to send a code to your phone or email each time you log in from a new device or browser.
Two-factor authentication is optional but recommended, especially if you use public computers or shared networks. Once you turn it on, you will need both your password and a code sent to your phone to log in. This makes it much harder for someone else to access your account even if they learn your password.
Troubleshooting common login problems
If you see an error message saying "Username or password is incorrect," double-check that you are typing them exactly as you set them up — passwords are case-sensitive, meaning capital and lowercase letters matter. If you are certain your password is correct, use the "Forgot password?" link to reset it.
If your account is locked after several failed login attempts, American Express will temporarily block access to protect your account. Wait 15 to 30 minutes and try again, or call the customer service number on the back of your card. If you are having trouble on the mobile app, try logging in on the website first to make sure your account is working, then delete and reinstall the app.
Paying your bill and managing your account after login
Once you are logged in, you can make a payment by clicking "Pay Now" or "Make a Payment" on your account dashboard. American Express lets you pay the full balance, the minimum payment, or any amount in between. You can pay from a bank account, another credit card, or through a wire transfer — each method has different processing times and fees.
You can also update your contact information, change your mailing address, read statements, set up automatic payments, and view your rewards balance from the same portal. If you need to report a lost or stolen card, call the number on the back of your card instead of trying to do it online — that process requires voice verification.
Frequently Asked Questions
Can I log into my Delta credit card account on the Delta website?
No. Delta credit cards are issued and managed by American Express, so you must log in through americanexpress.com. The Delta website does not have a credit card login portal. You can manage your SkyMiles rewards through Delta's website, but your card account itself is on the American Express site.
What if I never received the email to verify my account?
Check your spam or junk folder first — verification emails sometimes get filtered there. If you still do not see it after 10 minutes, go back to americanexpress.com and select "Resend verification email" or "Didn't receive your email?" You may also call the number on the back of your card and ask a representative to verify your account over the phone.
Can I use the same password for my American Express account and my Delta SkyMiles account?
You can, but it is not recommended. Your American Express account and your Delta SkyMiles account are separate systems with separate passwords. Using different passwords means that if one account is compromised, the other stays protected. American Express and Delta do not share login credentials.
Is it safe to log in on my phone or a public computer?
Logging in on your own phone is safe. On a public computer, use a private or incognito browser window, and always log out when you are done — do not stay logged in. If you use two-factor authentication, it adds an extra layer of protection on any device. Avoid logging in on computers at libraries, cafes, or other public places if you can.
What should I do if I think someone else has accessed my account?
Call the customer service number on the back of your card right away. Do not wait to log in online. A representative can freeze your account, review recent charges, and help you report fraud. American Express has fraud protection, but you need to report suspicious activity as soon as you notice it.
