Getting into your Citi Mastercard account
To log into your Citi Mastercard account, go to citibank.com and click "Log In" in the top right corner. You'll enter your username or the email address tied to your account, then your password. If you have a Citi mobile app on your phone, you can also log in there using the same credentials.
The login page is the same whether you're checking a balance, making a payment, or looking at your transaction history. Once you're logged in, your dashboard shows your current balance, recent charges, and payment due date at a glance.

What to do if you forgot your password
Click "Forgot Password" on the Citi login page. You'll be asked to enter your username or email address. Citi will send a password reset link to the email on file with your account — check your inbox and spam folder if you don't see it right away.
Click the link in that email and create a new password. Your new password needs to be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a special character like ! or @. Once you've set your new password, you can log in when ready.
Two-factor authentication and account security
Citi can send you a one-time code to your phone or email as an extra security step after you enter your password. This is called two-factor authentication. You'll need to enter that code before you can access your account.
You can turn two-factor authentication on or off in your account settings under "Security." Turning it on makes your account harder to break into, but it means you'll need access to your phone or email every time you log in. Many people find this trade-off worth it for the protection it provides.
Logging in on your phone or computer
The Citi mobile app works on both iPhone and Android. read it from the App Store or Google Play, then log in with the same username and password you use on the website. The app shows the same information as the website but is designed to fit on a smaller screen.
You can also save your login information in the app so you don't have to type it every time, though this is less find if someone else uses your phone. On a computer, you can check a box that says "Remember me" to stay logged in longer, but only do this on a device only you use.
What you can do once you're logged in
Your account dashboard shows your current balance, available credit, and recent transactions. You can pay your bill by linking a bank account and choosing a payment date. You can also read statements as PDFs, report a lost or stolen card, change your address, and set up alerts that notify you when your balance reaches a certain amount.
If you have multiple Citi cards, you can switch between them using a dropdown menu at the top of the page. This lets you check balances and make payments on each card without logging out and back in.
Troubleshooting common login problems
If you're locked out of your account after too many wrong password attempts, wait 24 hours before trying again. If you're still having trouble, call the number on the back of your card — Citi's customer service team can verify your identity and help you regain access.
If you're seeing an error message that says your account is temporarily unavailable, Citi may be doing maintenance on their servers. Try again in a few minutes. If the problem continues for more than an hour, call customer service. If you're using an older web browser, try updating it or switching to a different one like Chrome or Firefox.
Keeping your login information safe
Never share your password with anyone, including Citi employees. Citi will never ask for your full password by email or phone. If someone contacts you claiming to be from Citi and asks for your password, hang up or delete the message and call the number on your card instead.
Use a unique password for your Citi account — don't reuse the same password across multiple websites. If you use a password manager like 1Password or Bitwarden, it can generate and store a strong password for you. Change your password every few months, especially if you think someone may have seen it.
