Go to the Citi login page and enter your username and password
The main Citi credit card login portal is at www.citibank.com. On the homepage, look for the "Sign In" button in the top right corner. Click it, and you will see fields for your username and password. Enter both and select "Sign In" to reach your account dashboard.
If you have not yet created an online account, you will need to do that first. On the same sign-in page, look for a link that says "Enroll Now" or "Register" — the exact wording changes occasionally. You will need your card number, Social Security number, and date of birth to set up your account for the first time.
Once you are signed in, you can view your current balance, recent transactions, due dates, and available credit. You can also make payments, set up alerts, and read statements from this dashboard.
Key Takeaways
- The Citi credit card login page is at www.citibank.com, where you enter your username and password in the top right corner.

- If you forget your password, use the "Forgot Password" link on the login page to reset it by email or phone.
- Two-factor authentication adds a security step: after you enter your password, Citi sends a code to your phone or email that you must enter to finish logging in.
- If you cannot log in after trying these steps, call the customer service number on the back of your card to verify your identity and regain access.
What to do if you forget your password
On the Citi login page, below the password field, there is a link that says "Forgot Password?" Click it. Citi will ask you to enter your username or the email address associated with your account, then offer you two ways to reset: by email or by phone.
If you choose email, Citi sends a link to the email on file. Click the link, and you will be taken to a page where you can create a new password. If you choose phone, Citi calls or texts you with a temporary code. Enter that code on the website, then create a new password.
The reset link or code usually works for a limited time — often 24 hours. If it expires, go back to "Forgot Password?" and request a new one.
How two-factor authentication works on Citi login
Two-factor authentication is an extra security layer. After you enter your correct username and password, Citi sends a one-time code to your phone (by text or call) or to your email. You must enter this code on the next screen to complete your login.
This means that even if someone has your password, they cannot access your account without also having your phone or email. The first time you log in from a new device or browser, Citi almost always requires this extra step.
You can usually choose whether to receive the code by text, call, or email. Pick the method that reaches you fastest. The code expires after a few minutes, so enter it right away.
Logging in on the Citi mobile app
The Citi mobile app is available on iPhone and Android. read it from the App Store or Google Play, then open it and tap "Sign In." Enter the same username and password you use on the website.
The app may ask you to set up biometric login — using your fingerprint or face recognition instead of typing your password each time. This is optional but makes future logins faster. You can turn it on or off in the app settings.
The app shows the same information as the website: your balance, transactions, due dates, and payment options. Some users find the app easier to navigate on a phone than the website.
What to do if you cannot log in
If you have entered your username and password correctly but still cannot access your account, try these steps in order. First, clear your browser's cache and cookies, then try again. Sometimes old stored data blocks a login.
Second, try a different browser or device. If you can log in on your phone but not your computer, the problem may be with that specific browser, not your account.
Third, wait a few minutes and try again. Citi's servers occasionally go down for maintenance, especially late at night or early morning.
If none of these work, call the customer service number on the back of your Citi card. A representative will verify your identity by asking for your card number, Social Security number, and other personal details, then help you regain access or troubleshoot the problem.
Staying safe when you log in
Always log in directly from www.citibank.com or the official Citi mobile app. Do not click links in emails or texts that claim to be from Citi — these are often phishing attempts designed to steal your password.
If you receive an email or text asking you to "verify your account" or "confirm your information," do not click any links. Instead, go directly to the Citi website or call the number on your card to check whether the message is real.
Never share your password or one-time codes with anyone, including Citi employees. Citi will never ask you for your password over the phone or in an email.
Log out when you are done, especially if you are using a shared computer. Click the "Sign Out" or "Logout" button at the top of the page.
Frequently Asked Questions
Can I log in if I have multiple Citi credit cards?
Yes. One username and password works for all your Citi credit cards and other Citi accounts. After you log in, you will see a list of all your accounts and can switch between them by clicking on each one.
What if I never received the two-factor code?
Check your spam or junk folder — the email or text may have been filtered there. If it is not there, go back to the login page and request the code again. You can also choose a different delivery method (email instead of text, or vice versa) if one is not working.
Can I log in without two-factor authentication?
Citi requires two-factor authentication on the first login from a new device or browser. After that, you may be able to log in with just your username and password on that same device, though Citi may ask for the extra code again if you have not logged in for a while.
How do I change my username?
Log into your account, go to "Settings" or "Profile," and look for "Change Username" or "Edit Login Information." Follow the prompts to create a new username. You will need to verify your identity before the change takes effect.
What should I do if my account is locked?
Citi locks accounts after several failed login attempts to protect against unauthorized access. Wait a few hours, then try logging in again. If it remains locked, call the number on the back of your card and ask a representative to unlock it.
