What to Do If You Forget Your Password
Click "Forgot Password" on the Citi login page. You will be asked to enter your username or email address. Citi will then send a password reset link to the email on file or offer to verify your identity by phone.
If you choose email reset, check your inbox and spam folder for a message from Citi. The reset link usually expires within a few hours, so act on it promptly. Create a new password that is at least eight characters long and includes uppercase letters, lowercase letters, numbers, and symbols for security.
If you do not receive an email or prefer phone verification, select that option instead. A representative will ask you security questions based on your account history to confirm your identity before issuing a temporary password.
Two-Factor Authentication and Security
Citi uses two-factor authentication to protect your account from unauthorized access. After you enter your correct password, the system sends a one-time code to your registered phone number via text message or to your email address. You must enter this code within a set time window — usually five to ten minutes — to complete login.
If you do not receive the code, you can request it be resent or choose an alternative delivery method if you have multiple phone numbers or email addresses on file. Some accounts also offer authentication through the Citi mobile app itself, which generates codes without requiring a text or email.
Never share your one-time code with anyone, including Citi employees. Citi will never ask for this code by phone or email. If someone contacts you claiming to be from Citi and requests your code, hang up and call the number on the back of your card instead.
Viewing Your Account Details and Transactions
Once logged in, your dashboard shows your current balance, available credit, recent transactions, and rewards balance. Click "Transactions" or "Activity" to see a detailed list of charges, payments, and credits. You can filter by date range or merchant to find a specific purchase.
Your rewards points or miles appear in a dedicated section, usually labeled "AAdvantage Miles" or "Rewards." This shows your current balance, miles expiring soon, and options to redeem or transfer miles to your AAdvantage frequent flyer account if you have one.
You can also read statements as PDF files, set up automatic payments, update your contact information, and manage notification preferences — such as alerts for large purchases or payments due — all from the main account page.
Making Payments Through Your Online Account
To pay your Citi AAdvantage card balance, log in and select "Make a Payment" or "Pay Now." You can pay the full balance, the minimum payment, or a custom amount. Choose your payment method: bank account transfer (usually free and takes one to two business days) or debit card (may have a fee and posts when ready).
If you set up automatic payments, your account will deduct the same amount on the same day each month. You can choose to pay the full statement balance, the minimum payment, or a fixed dollar amount. Review your automatic payment schedule in the "Payments" or "Autopay" section to confirm the date and amount.
Payments made before 8 p.m. Eastern Time on a business day usually post the next day. Payments made after that time or on weekends post the following business day. Your due date appears on your statement and in your online account.
Troubleshooting Login Problems
If you see an error message saying your username or password is incorrect, verify that Caps Lock is off and that you are entering the correct information. Passwords are case-sensitive. If you are certain your password is correct, use the "Forgot Password" option to reset it.
If your account is locked after multiple failed login attempts, wait 24 hours before trying again, or call the customer service number on the back of your card to unlock it when ready. Some accounts are temporarily locked for security reasons, and a representative can confirm your identity and restore access.
If you cannot reach the Citi website or the app crashes during login, try clearing your browser cache and cookies, then log in again. If the problem persists, try a different browser or device. You can also call the number on your card to speak with a representative who can help you access your account information by phone.
Frequently Asked Questions
Can I log in with my username instead of my email address?
Yes. Citi accepts either your username or the email address associated with your account at login. If you created a username during enrollment, you can use that instead of typing your full email address. Both options work equally well.
What should I do if I do not recognize a transaction on my account?
Log in and review the transaction details, including the merchant name and date. If you believe the charge is fraudulent, contact Citi when ready by calling the number on the back of your card. Do not use the contact information from an email, as scammers sometimes send fake fraud alerts. Citi can dispute the charge and issue a temporary credit while they investigate.
Is it safe to log in on a public or shared computer?
It is safer to log in on your own device. If you must use a public computer, always log out completely when finished and clear the browser history. Do not check the "Remember Me" or "Stay Logged In" option on shared devices. Consider using your phone or a personal computer instead whenever possible.
Can I change my password after I log in?
Yes. Once logged in, look for "Settings," "Security," or "Account Preferences" in the menu. Select "Change Password" and enter your current password, then create a new one. Make sure your new password is unique and not used on other websites.
What if I have multiple Citi cards?
You can manage all your Citi cards from a single online account if they are linked to the same username and email address. After login, you can switch between cards using a dropdown menu or card selector. If your cards are under different email addresses, you will need separate logins for each account.
