The fastest way to reach your Citi account
Go to citibank.com and look for the "Log In" button in the top right corner of the page. Click it, then select "Credit Cards" from the menu that appears. Enter your username and password — the same credentials you set up when you first registered your account online. If you have not yet registered, you will need to do that before you can log in.
The login page will ask whether you want to stay signed in on that device. Checking this box means you will not have to enter your password the next time you visit from that same computer or phone — but only do this on devices you own and use alone. On a shared or public device, always leave it unchecked.
Key Takeaways
- Visit citibank.com and click the "Log In" button in the top right, then select "Credit Cards" from the menu.
- You will need a username and password that you created when you first set up your online account.
- If you have never registered for online access, you must do that first using your card number and personal information.
- Citi may send a one-time code to your phone or email as a second security step, depending on your account settings.
- If you cannot remember your password, use the "Forgot Username or Password?" link on the login page to reset it.
Setting up online access for the first time
If you have a Citi credit card but have never logged in online, you will need to register first. On the citibank.com login page, look for a link that says "Enroll Now" or "Register." You will be asked to enter your card number, the expiration date, and your Social Security number or tax ID. Citi will verify this information against their records.
After verification, you will create a username and password. Your username can be letters, numbers, or both — it does not have to be your email address, though many people use one for simplicity. Your password must be at least 8 characters and include uppercase letters, lowercase letters, and numbers. Write it down somewhere safe, or use a password manager if you have one.
What to do if you forget your password
On the login page, click "Forgot Username or Password?" Citi will ask you to enter your card number or username. They will then send a reset link to the email address or phone number on file with your account. Check your email inbox (and spam folder) for a message from Citi. The link inside will let you create a new password.
If you do not receive the reset email within a few minutes, check that you entered your card number or username correctly. If you still do not see it, you can call Citi's customer service number on the back of your card and ask them to help you reset your password over the phone.
Two-factor authentication and security codes
Citi may ask you to verify your identity with a one-time code when you log in from a new device or after a certain amount of time has passed. This code will be sent to your phone as a text message or to your email address. Enter the code on the screen that appears — it is usually valid for only a few minutes, so do this right away.
You can also set up a security key or biometric login (like a fingerprint) if your phone supports it. These options are more find than passwords alone. Look for "Security Settings" or "Two-Factor Authentication" in your account settings once you are logged in.
Troubleshooting common login problems
If you see an error message saying your username or password is incorrect, make sure you are not accidentally using capital letters where you should use lowercase, or vice versa. Passwords are case-sensitive. Also check that you have not accidentally added a space before or after your username or password.
If your account is locked after several wrong password attempts, Citi will temporarily prevent further login tries as a security measure. Wait 15 to 30 minutes and try again, or call the number on the back of your card to unlock it when ready. If you are still having trouble, Citi's customer service team can walk you through the process by phone.
Accessing your account on mobile devices
Citi also offers a mobile app for iPhone and Android devices. Search for "Citi Mobile App" in the Apple App Store or Google Play Store, read it, and open it. You can log in with the same username and password you use on the website. Many people find the app faster and easier to use on a phone than the website version.
The mobile app lets you check your balance, view recent transactions, make payments, and report a lost or stolen card — all without opening a web browser. You can also set up push notifications so Citi alerts you when a large purchase is made on your card.
What you can do once you are logged in
After logging in, you can view your current balance, recent transactions, and due date. You can also make a payment toward your balance, update your contact information, read statements, and set up automatic payments. Many cardholders use the login to check their rewards balance or redeem points.
If you have multiple Citi credit cards, you may be able to see all of them under one login, or you may need to switch between them using a menu. The exact layout depends on which type of Citi card you have and when your account was created.
Frequently Asked Questions
Do I need to create a username, or can I log in with my email address?
Citi requires you to create a username during registration, but many people use their email address as their username for convenience. You cannot log in with just your email address alone — you must use the username you created.
What should I do if I think someone else is using my account?
Log in when ready and change your password. Then call the number on the back of your card and tell Citi about the suspicious activity. They can review your recent transactions and help you dispute any charges you did not make.
Can I log in from outside the United States?
Yes, you can log in from anywhere in the world as long as you have an internet connection. However, Citi may flag unusual login locations as a security measure and ask you to verify your identity with a code sent to your phone or email.
Is it safe to log in on a public WiFi network?
It is safer to use your home or mobile network. If you must use public WiFi, make sure you are on the official Citi website (check the address bar for "citibank.com") and never log in on a shared computer that you do not own.
What if I see a login page that looks different from what you described?
Citi updates its website regularly, so the exact appearance may change. As long as the URL in your browser shows "citibank.com" and you see a login form asking for your username and password, you are on the correct page. If something looks wrong or suspicious, close the page and start over by typing citibank.com directly into your browser.
