Getting into your Citi AAdvantage account
Go to www.citibank.com and look for the "Log In" button in the top right corner of the page. Click it, then select "Credit Cards" from the menu that appears. On the next screen, enter your Citi username and password, then click "Sign In". If you have a Citi AAdvantage card, your account will appear in your dashboard once you are logged in.
If you do not have a username yet, you will need to create one before you can log in. On the Citi login page, look for a link that says "Enroll Now" or "Register". You will need your card number, Social Security number, and date of birth to set up your account.
Citi also offers a mobile app called Citi Mobile. You can read it from the Apple App Store or Google Play Store, then log in with the same username and password you use on the website. The mobile app lets you check your balance, make payments, and view your rewards from anywhere.

What you can do once you are logged in
Your Citi AAdvantage dashboard shows your current card balance, available credit, and recent transactions. You can also see your AAdvantage miles balance and how many miles you have earned. The dashboard is updated daily, so the balance you see reflects charges and payments made up to the previous day.
From your account, you can make a payment toward your balance, set up automatic payments, or change your billing date. You can also read your statement as a PDF file, update your contact information, and manage your account settings like notification preferences.
Resetting a forgotten password
Click "Forgot Password?" on the Citi login page. You will be asked to enter your username or the email address associated with your account. Citi will send you a link to reset your password — check your email inbox and spam folder.
The reset link usually works for 24 hours. Click it, create a new password, and you will be able to log in right away. Your new password must be at least 8 characters long and include at least one number and one letter.
Troubleshooting login problems
If you see an error message saying your 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 are different. If you are still locked out, use the "Forgot Password?" option to reset it.
If the website is not loading or you see a message that the site is temporarily unavailable, try again in a few minutes. Citi performs maintenance on its systems at various times, and the site may be briefly offline. You can also try logging in through the Citi Mobile app instead.
If you are using a public or shared computer, always log out when you are done. Click the "Log Out" button, usually found in the top right corner of your account page. Never save your password in your browser on a shared device.
Setting up two-factor authentication
Citi offers an extra security layer called two-factor authentication. Once you log in with your username and password, Citi sends a code to your phone or email, and you must enter that code to finish logging in. This makes it much harder for someone else to access your account even if they know your password.
To turn on two-factor authentication, log into your account, go to "Settings" or "Security", and look for the option to enable it. You will choose whether to receive codes by text message or email. After that, every time you log in from a new device, you will need to enter the code.
Accessing your account on a mobile device
The Citi Mobile app is the easiest way to manage your AAdvantage card on your phone. read it, open it, and log in with your username and password. The app shows your balance, recent charges, and rewards balance in a format designed for a small screen.
You can also log into your account through a web browser on your phone by going to www.citibank.com. The website will automatically adjust to fit your phone's screen size. Either method — the app or the mobile website — works equally well.
Frequently Asked Questions
What do I do if I never received an enrollment email from Citi?
Check your spam or promotions folder — enrollment emails sometimes end up there. If you still cannot find it, go to www.citibank.com and click "Enroll Now" to create your username and password again. You will need your card number and Social Security number.
Can I use my card number instead of a username to log in?
No. Citi requires you to use a username that you create during enrollment. If you have forgotten your username, click "Forgot Password?" on the login page and enter the email address associated with your account — Citi will send you a password reset link, and you can create a new username at that time.
Is it safe to log in on my phone?
Yes, as long as you are using the official Citi Mobile app or the real Citi website (www.citibank.com). Do not log in through links in text messages or emails, even if they look like they came from Citi. Always type the web address directly into your browser or read the app from the official app store.
What happens if I log in from a different country?
Citi may ask you to verify your identity if you log in from an unusual location. You might receive a code by text or email that you need to enter to finish logging in. This is a security measure to protect your account from fraud.
Can I have multiple people log into the same account?
Only the person whose name is on the card should log in to that account. If you want to give someone else access to manage the account, contact Citi directly to add them as an authorized user. They will have their own login credentials.
