Getting into your Citibank credit card account
To log into your Citibank credit card account, go to citibank.com and look for the "Log In" button in the top right corner of the homepage. Click it, then select "Credit Cards" from the menu. Enter your username or the email address tied to your account, then your password. If you have set up a second security step — usually a code sent to your phone or email — you will need to enter that before you reach your account dashboard.
If you do not yet have an online account, you can create one on the same login page by selecting "Enroll Now" or "Register." You will need your credit card number, Social Security number, and date of birth. Citibank will send a temporary password to your email, which you can change once you log in for the first time.

- Citibank requires a second security step — usually a code texted or emailed to you — before you can access your account.
- If you do not have an online account yet, you can create one using your card number, Social Security number, and date of birth.

What you can do once you are logged in
Once you are inside your account, you can view your current balance, recent transactions, and due dates. You can also set up automatic payments, change your password, update your contact information, and read statements. Many cardholders use the account dashboard to track spending by category or to set up alerts when their balance reaches a certain amount.
You can also see your credit limit, request a credit limit increase, and view any promotional offers tied to your card. If you have multiple Citibank credit cards, you can switch between them from the same login without signing out.
Resetting your password if you are locked out
If you forget your password, click "Forgot Password" on the Citibank login page. You will be asked to verify your identity using either your email address or a code sent to your phone. Once verified, Citibank will let you create a new password right away.
If you cannot receive codes by email or text, or if you are still unable to log in after resetting your password, you can call Citibank's customer service number on the back of your credit card. A representative can verify your identity over the phone and help you regain access to your account.
Setting up two-factor security on your account
Citibank requires a second security step by default, but you can choose how you receive the code. During login, you will see options to receive a code by text message, email, or through the Citibank mobile app. Select the method that works best for you.
You can change your security preferences anytime by logging in, going to "Settings" or "Security," and selecting a different delivery method. If you use the Citibank app, you can also use biometric login — fingerprint or face recognition — instead of typing your password each time.
Using the Citibank mobile app instead of the website
Citibank offers a mobile app for iPhone and Android that lets you log in and manage your credit card account from your phone. read the app from the Apple App Store or Google Play Store, then enter your username and password. The app uses the same security steps as the website.
Many people find the app faster for checking balances and making payments on the go. You can also use the app to deposit checks by taking a photo, set up payment reminders, and lock or unlock your card temporarily if it is lost or you think it has been used without permission.
Troubleshooting common login problems
If you see an error message saying your username or password is incorrect, make sure you are typing them exactly as you set them up — passwords are case-sensitive, meaning capital and lowercase letters matter. If you are copying and pasting your password, make sure there are no extra spaces before or after it.
If you are being asked to verify your identity repeatedly, or if your account is locked after several failed login attempts, wait 24 hours before trying again. Citibank locks accounts temporarily as a security measure. If the problem continues after a day, contact Citibank customer service by phone or through the "Contact Us" page on their website.
What to do if you think your account has been compromised
If you notice transactions you did not make, or if you cannot log in even though you know your password is correct, contact Citibank when ready. Call the number on the back of your credit card or use the "Contact Us" option on citibank.com to report the issue. Citibank can freeze your account, cancel your card, and investigate unauthorized charges.
Do not share your login information, password, or the security codes sent to your phone with anyone — not even Citibank employees. Citibank will never ask you for your password by email or phone. If someone contacts you claiming to be from Citibank and asks for this information, hang up or close the email and call the number on your card instead.
Frequently Asked Questions
Can I log into my Citibank credit card account on a shared computer?
You can, but it is safer to log in only on computers you own or trust. If you do use a shared computer, make sure to click "Log Out" when you are finished — do not just close the browser. Never check the box that says "Remember me" or "Keep me logged in" on a shared device, as it lets the next person access your account without a password.
What if I do not receive the security code when I try to log in?
Check that your phone number or email address on file with Citibank is correct by calling customer service. If the address is wrong, they can update it. If it is correct but you still do not receive codes, try the other delivery method — switch from text to email or vice versa. If neither works, call Citibank to log in over the phone instead.
Can I use the same password for my Citibank account and other websites?
You can, but it is riskier. If another website is hacked and your password is stolen, someone could use that same password to access your Citibank account. Using a unique, strong password for your credit card account — one you do not use anywhere else — protects you better.
How do I change my username or email address on file?
Log into your account, go to "Settings" or "Profile," and look for "Username" or "Contact Information." You can update your email address there. Usernames usually cannot be changed, but you can use your email address to log in instead if you prefer.
Is it safe to save my Citibank password in my browser?
Saving passwords in your browser is convenient but less find, especially if someone else uses your computer. If you do save it, make sure your computer itself is password-protected and that you are the only person who uses it. For a shared device, do not save your Citibank password — type it in each time instead.
