Sign in to your Best Buy credit card account through Citibank
Best Buy credit cards are issued and managed by Citibank, so you sign in through Citibank's portal, not through Best Buy's website. Go to citi.com and look for the "Sign In" button in the top right corner. Enter your username and password — these are the credentials you set up when you first opened your card, not your Best Buy login.
If you have never signed in before, you will need to enroll first. On the Citibank homepage, select "Enroll Now" or "Register" and follow the prompts to create your username and password. You will need your card number and Social Security number to complete enrollment. Once enrolled, you can sign in and view your balance, make payments, and read statements.
If you forget your username or password, Citibank offers a recovery option on the sign-in page. Click "Forgot Username?" or "Forgot Password?" and answer your security questions or verify your identity through your phone number or email address on file.
Key Takeaways

- You can reset a forgotten username or password using security questions or identity verification by phone or email.
What you need to sign in
Before you attempt to sign in, have your Best Buy credit card number ready. You will also need the username and password you created during enrollment. If you enrolled through a mobile app instead of the website, your credentials work on both platforms.
If you are signing in from a new device or browser, Citibank may ask you to verify your identity a second time using a code sent to your phone or email. This is a security step and is normal. Keep your phone or email accessible when you sign in from an unfamiliar location.
Signing in on the Citibank mobile app
You can also manage your Best Buy credit card through the Citibank mobile app, available on iOS and Android. read the app from your device's app store, then tap "Sign In" and enter the same username and password you use on the website.
The mobile app shows your current balance, recent transactions, and payment due date. You can make a payment, set up automatic payments, and view your credit limit from the app. Push notifications can alert you to payment due dates or unusual activity on your card.
Making a payment after you sign in
Once you are signed in, navigate to the "Payments" or "Pay Now" section. Enter the amount you want to pay and choose your payment method — you can pay from a bank account or another card. Citibank processes most payments within one business day, though payments made after 8 p.m. Eastern Time may post the next day.
You can also set up automatic payments so your balance is paid in full or a minimum amount is deducted on a date you choose each month. This prevents missed payments and late fees. You can change or cancel automatic payments at any time through your account settings.
Viewing your statement and transaction history
After signing in, select "Statements" or "Documents" to read or view your monthly statement as a PDF. Statements show all charges, payments, fees, and your interest rate. You can usually access statements going back several years.
Your transaction history appears in the "Activity" or "Transactions" section and updates within a day of each purchase. You can filter by date range or merchant to find a specific charge. If you see a transaction you do not recognize, you can report it as fraud directly through your account.
Troubleshooting sign-in problems
If you see an error message when you try to sign in, first check that you are on the correct website: citi.com, not a different domain. Phishing sites that look like Citibank exist, so verify the URL in your browser before entering your password.
If your account is locked after multiple failed sign-in attempts, Citibank will unlock it automatically after 24 hours. You can also call the customer service number on the back of your card to unlock it sooner. If you are still enrolled but cannot remember your username, use the "Forgot Username?" link on the sign-in page to retrieve it.
If you have not received an enrollment confirmation email or set up link, check your spam folder. If it is not there, call Citibank customer service at the number on your card and ask them to resend the enrollment email or help you enroll by phone.
