Go to citibank.com and enter your username and password
The main Citi login page is at citibank.com. Click the "Log In" button in the top right corner. Enter your username (or the email address linked to your account) and your password, then click "Sign In".
If you have not yet set up online access, you will need to register first. You can do this from the same login page by clicking "Enroll Now" and following the prompts to create a username and password.
Citi may ask you to verify your identity using a code sent to your phone or email. This is a security step. Enter the code when prompted to complete your login.
Key Takeaways
- Visit citibank.com, click "Log In" in the top right, and enter your username and password.
- If you do not have online access yet, click "Enroll Now" on the login page to create a username and password.
- Citi will send a verification code to your phone or email as a security check — enter it to finish logging in.
- If you forget your password, click "Forgot Password?" on the login page and follow the recovery steps.
- You can also use the Citi Mobile App instead of the website if you prefer to manage your card on your phone.
What to do if you forgot your password
Click "Forgot Password?" on the Citi login page. You will be asked to enter your username or the email address on your account. Citi will send a password reset link to that email address.
Open the email and click the reset link. You will be taken to a page where you can create a new password. Make sure your new password is at least 8 characters long and includes uppercase letters, lowercase letters, numbers, and a special character (like ! or #).
After you set your new password, return to the login page and sign in with your username and the new password.
Using the Citi Mobile App instead of the website
If you prefer to check your card on your phone, read the Citi Mobile App from the Apple App Store or Google Play Store. Open the app and tap "Log In" at the bottom of the screen.
Enter your username and password the same way you would on the website. Citi will send a verification code to your phone — enter it to complete your login. After your first login, you can set up biometric login (fingerprint or face recognition) so you do not have to type your password every time.
What you can do once you are logged in
After you log in, you can view your current balance, recent transactions, and due date. You can also make a payment, read statements, update your contact information, and change your password or security settings.
If you have multiple Citi cards or accounts, you may see a menu to switch between them. Look for a dropdown or menu option that shows your account name or card number.
Troubleshooting common login problems
If you see an error message that says your username or password is incorrect, make sure you are typing them exactly as you set them up. Passwords are case-sensitive, which means capital letters matter. If you are still stuck, use the "Forgot Password?" link to reset it.
If Citi locks your account after several failed login attempts, you may need to wait a few hours before trying again. This is a security measure to protect your account. If the account remains locked, contact Citi customer service at the number on the back of your card.
If the website or app is running slowly or will not load, try clearing your browser's cache and cookies, or restart the app. If the problem continues, Citi may be performing maintenance — check back in a few minutes.
Setting up two-factor authentication for extra security
Citi offers two-factor authentication, which adds an extra layer of security to your account. Once you log in with your username and password, Citi sends a code to your phone or email that you must enter before you can access your account.
To turn on two-factor authentication, log in to 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 you turn it on, you will need to enter a code every time you log in from a new device or browser.
Frequently Asked Questions
Can I log in to Citi on my work computer?
Yes, you can log in from any computer or phone with an internet connection. However, for security reasons, avoid logging in on shared or public computers. If you do log in on a shared device, make sure to click "Log Out" when you are finished, and do not check the "Remember Me" box.
What if I see a message saying my account is locked?
Your account may be locked if you entered your password incorrectly several times in a row. Wait a few hours and try again. If it remains locked, call the customer service number on the back of your card to unlock it.
Do I need to log in every time I visit citibank.com?
Not necessarily. When you log in, you can check a box that says "Remember Me" or "Stay Signed In." This keeps you logged in for a period of time, though Citi may ask you to log in again for security reasons. Do not use this option on shared computers.
Can I change my username after I set it up?
Yes. Log in to your account, go to "Settings" or "Profile," and look for the option to change your username. You will need to enter your current password to confirm the change.
What should I do if I think someone else logged into my account?
Change your password when ready using the "Forgot Password?" link. Then log in with your new password and check your recent transactions for anything you do not recognize. If you see unauthorized charges, contact Citi customer service right away at the number on the back of your card.
