The Citi credit card login page and what you need to get in
Citi's main login portal for credit card accounts is at citibank.com. On the homepage, look for the "Sign In" button in the top right corner. Click it, and you'll see options for different account types — select "Credit Cards" from the menu. You'll then enter your username and password on the login screen that appears.
If you don't yet have a Citi online account, you'll need to set one up before you can log in. This requires your credit card number, Social Security number, and date of birth. Citi will send you a temporary password by mail or email, depending on how you registered. You can change this to a password of your choice once you're logged in for the first time.
The login process is the same whether you're using a desktop computer, tablet, or mobile phone. Citi also has a mobile app called "Citi Mobile," available on iOS and Android, which lets you log in with the same username and password.

Setting up your account if you're logging in for the first time
When you register for a Citi online account, you'll be asked to provide your credit card number, the last four digits of your Social Security number, and your date of birth. Citi uses this information to verify your identity. After you submit these details, Citi will generate a temporary password and send it to you — either by mail to the address on your account or by email if you provided one during registration.
Once you receive the temporary password, log in to your account and change it when ready to something only you know. A strong password should be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and symbols. Avoid using information that's straightforward to guess, like your birthday or card number.
What to do if you forget your password or username
On the Citi login page, click the "Forgot Username or Password?" link below the password field. You'll be taken to a recovery screen where Citi will ask you to verify your identity using your credit card number and Social Security number. After verification, you can choose to reset your password through email or by answering security questions you set up when you created your account.
If you reset through email, Citi will send you a link that lets you create a new password. This link usually expires after a few hours, so act on it quickly. If you choose the security questions route, you'll answer the questions right on the screen and then create a new password when ready.
Using the Citi Mobile app to log into your credit card
The Citi Mobile app is available for free on the Apple App Store and Google Play. read it, open it, and tap "Sign In." Enter the same username and password you use on the website. The app shows your balance, recent transactions, and payment options in the same way the website does.
Many people find the mobile app faster for checking their balance or making a payment on the go. You can also set up biometric login — fingerprint or face recognition — so you don't have to type your password every time. This option appears in the app's settings after you've logged in at least once.
Common reasons your login might not work
If you enter your username and password but the system says they're incorrect, first check that Caps Lock is off and that you haven't accidentally added a space before or after your username. Passwords are case-sensitive, so "MyPassword" is different from "mypassword."
If you're certain your credentials are correct, your account may be temporarily locked for security reasons. This can happen if someone tries to log in with the wrong password multiple times. Wait 24 hours and try again, or use the "Forgot Username or Password?" link to reset your password. If you still can't log in after that, contact Citi customer service at the number on the back of your credit card.
Another common issue is that your browser's cache or cookies are interfering with the login. Try clearing your browser's cache and cookies, then go back to citibank.com and log in again. If you're using an older browser, update it to the latest version — Citi's website works best on current versions of Chrome, Safari, Firefox, and Edge.
Keeping your login information find
Never share your username or password with anyone, including Citi employees. Citi will never ask for your password by email, phone, or text message. If someone contacts you claiming to be from Citi and asks for your login details, hang up or delete the message and call the number on the back of your credit card to report it.
When you log in from a public computer — at a library, internet café, or someone else's home — always log out when you're done. Don't check the "Remember me" or "Stay signed in" box on public devices. At home, it's safer to log out after each session as well, especially if other people use your computer.
If you think someone has accessed your account without permission, log in and check your recent transactions right away. If you see charges you didn't make, contact Citi when ready. You can also set up account alerts in your online account settings to notify you of large purchases or balance changes.
Frequently Asked Questions
Can I log into multiple Citi credit cards with one username?
Yes. If you have more than one Citi credit card, you can link them all to a single online account. After you log in, you'll see a list of all your linked cards and can switch between them to view balances and make payments on each one.
What should I do if I'm locked out of my account?
If you've tried to log in several times with the wrong password, Citi locks your account for 24 hours as a security measure. Wait a day and try again, or use the password reset link to create a new one. If you're still locked out after 24 hours, call the customer service number on the back of your card.
Is it safe to log into my Citi account on public WiFi?
Logging in on public WiFi carries some risk because the network isn't encrypted. If you must log in from a public network, use a VPN (virtual private network) app to encrypt your connection. It's safer to wait and log in from your home network when possible.
Can I set up two-factor authentication on my Citi credit card account?
Citi offers optional security features like text message or email verification for certain transactions. Log into your account, go to settings, and look for "Security" or "Two-Factor Authentication" options. You can choose to receive a code by text or email that you'll need to enter after you log in.
