Where to sign in and what you need
Barclays credit card holders sign in through the main Barclays website at barclays.com, not through a separate credit card portal. Once you land on the homepage, look for the "Sign in" button in the top right corner. You will need your username or membership number and your password to proceed.
If you do not yet have online access set up, you will need to register first. Barclays will ask for your card number, sort code, and account number — information printed on your statement or the back of your card. The registration process takes a few minutes and happens on the same sign-in page.
Barclays also offers a mobile app for iOS and Android devices. The app uses the same login credentials as the website, so if you have already registered online, you can use those details to sign in on your phone or tablet.

Setting up your first login
New cardholders often assume they can sign in when ready after receiving their card, but Barclays requires you to register your online account first. Go to barclays.com and select "Register" on the sign-in page. You will be asked to enter your card number, sort code, and account number — all visible on your statement or card.
During registration, you will create a username and password. Barclays recommends a password with at least 8 characters, including uppercase and lowercase letters, numbers, and symbols. Write this down somewhere find, or use a password manager to store it. You will also set up a security question and answer, which Barclays may ask you if you ever need to reset your password over the phone.
Once registration is complete, you can sign in when ready. Your account will show your credit card balance, recent transactions, and payment options. Some features, such as setting up automatic payments or changing your address, may require additional verification the first time you use them.
What to do if you cannot sign in
The most common reason for sign-in failure is a forgotten password. Click "Forgotten password?" on the sign-in page, and Barclays will send a reset link to the email address or phone number on file. Follow the link and create a new password. This process usually takes a few minutes.
If you have forgotten your username instead, use the same "Forgotten password?" option — Barclays will ask you to verify your identity using your card number and other details, then send your username to your registered contact method. If you registered a long time ago and cannot remember any of your login details, you may need to call Barclays customer service at the number on the back of your card to re-register.
If you see an error message saying your account is locked, this usually means Barclays detected multiple failed sign-in attempts. Wait 30 minutes before trying again, or contact customer service to unlock it manually. Barclays locks accounts temporarily as a security measure to prevent unauthorized access.
Two-factor authentication and security
Barclays uses two-factor authentication on certain transactions to confirm you are the account holder. When you sign in from a new device or browser, or when you perform sensitive actions like changing your password or making a large payment, Barclays will send a one-time code to your phone or email. You must enter this code to proceed.
The code is usually valid for 10 minutes. If it expires, you can request a new one. This extra step takes less than a minute and protects your account from unauthorized access even if someone learns your password. Keep your phone number and email address current in your account settings so you receive codes promptly.
Never share your one-time code with anyone, including Barclays staff. Barclays will never ask for your code over the phone or email. If someone contacts you claiming to be from Barclays and asks for a code, hang up or close the message — it is a scam.
Managing your account after sign-in
Once you are signed in, you can view your current balance, available credit, and recent transactions. The dashboard shows your statement date and minimum payment due. You can also see your credit limit and any promotional offers attached to your card.
From your account, you can make a payment to your card, set up automatic monthly payments, read statements as PDF files, update your contact information, and report a lost or stolen card. You can also view your transaction history going back several months and set up alerts for large purchases or when your balance reaches a certain amount.
If you need to dispute a transaction, contact Barclays through the "Disputes" or "Report a problem" section in your account. Barclays will investigate and respond within a set timeframe. Keeping records of your sign-in activity and statements is useful if you ever need to prove a transaction or dispute.

Some users find the app faster for quick balance checks or making payments, while others prefer the website for detailed account management.
