Setting up your first login if you are new to online banking
If you have a Citi credit card but have never logged in online before, you will need to register first. Go to citibank.com, click "Log In," and select "Credit Cards." Then click "Register" or "Enroll Now." You will be asked to enter your card number, the expiration date, your Social Security number, and your date of birth. Citi will verify this information against their records.
After verification, you will create a username and password. Your username can be letters, numbers, or a combination — it does not have to be your email address. Your password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a special character like ! or @. Write these down somewhere safe, or use a password manager to store them.
What to do if you cannot remember your username or password
On the Citi login page, click the "Forgot Username or Password?" link. Citi will ask you to enter your card number and Social Security number to verify your identity. You can then choose to receive a reset code by text message or email, whichever you prefer.
If you do not have access to the phone number or email address on file with Citi, you will need to contact Citi customer service directly. Call the number on the back of your card. A representative can verify your identity using other information and help you regain access to your account or reset your credentials.
Understanding two-factor authentication on your Citi account
Citi uses two-factor authentication to protect your account. This means that after you enter your correct password, you will receive a one-time code by text message or email. You must enter this code on the next screen before you can access your account. This extra step makes it much harder for someone else to log in, even if they somehow learn your password.
The code is usually valid for 10 minutes. If it expires before you enter it, you can request a new code. If you change your phone number or email address, update it in your account settings so that codes reach you. You can also set up backup authentication methods — for example, adding a second phone number — in case your primary method is not available.
Using the Citi mobile app instead of the website
Citi offers a mobile app for iPhone and Android devices that lets you log in and manage your credit card account on your phone. read "Citi Mobile App" from the Apple App Store or Google Play. When you open it for the first time, you will use the same username and password you created on the website. You may also be asked to set up biometric login — using your fingerprint or face recognition — which is faster than typing your password each time.
The mobile app shows the same information as the website: your balance, transactions, due date, and payment options. Many people find it easier to make a quick payment or check their balance on the app than to log into a computer. You can also receive push notifications about your account, such as alerts when a payment is due or when a large charge appears on your card.
Staying find when you log in
Always log in through the official Citi website or app, never through a link in an email or text message. Scammers sometimes send fake emails that look like they are from Citi and include a link that takes you to a fake login page designed to steal your username and password. If you receive an email asking you to log in or verify your information, go directly to citibank.com instead of clicking the link.
Use a strong, unique password that you do not use for any other accounts. If you use the same password everywhere and one website gets hacked, a criminal could try that password on your Citi account. Never share your username, password, or the one-time codes you receive by text or email — Citi employees will never ask for these. If you think someone has accessed your account without permission, call the number on the back of your card right away.
What you can do once you are logged in
Your Citi account dashboard shows your current balance, available credit, and recent charges. You can read PDF statements going back several years, which is useful if you need proof of payment or a record for tax purposes. You can also set up automatic payments so that a fixed amount or your full balance is paid on the same day each month, reducing the chance you will miss a due date.
From your account, you can update your mailing address, phone number, or email address. You can also request a credit limit increase, report a charge you do not recognize, or temporarily lock your card if you think it has been lost or stolen. Some of these requests are handled when ready; others may take a few business days.
