Click on the headings below to get more information about how we protect you:

  • To ensure you can access your accounts over the Internet with the utmost confidence, we use the highest levels of industry standard security. As part of this security our connections use TLS1.2, the connection is encrypted using the Advanced Encryption Standard (AES) and keys are exchanged via Diffie-Hellman ciphers.

  • This feature aims to protect you against unauthorised access.

    Online Banking will automatically log you out after 5 minutes of inactivity. However 60 seconds before you are timed out due to inactivity, you will see a prompt and will have the option to remain logged in.

    Mobile Banking will automatically log you out after 4 minutes of inactivity.

    You must be actively browsing to stay connected (i.e. switching between accounts).

    Please note: Scrolling through statements does not count as active browsing. Active browsing is when you are clicking on links within the website, i.e. selecting a different tab on the left of the screen or switching between accounts.

  • Each time you log in to Online Banking we will display the details of your last log in. This is an additional security measure that we have taken to ensure that you can see if someone has fraudulently accessed your accounts online.

    The details shown are the day, date and time on which you last accessed the service. It is important that you check your last log in every time you log in to Online Banking. It will be displayed in the top navigation bar. If you are suspicious of the last log in shown and do not recall logging into Online Banking on that date, please contact our Customer Service Advisers for assistance.

  • The Card Reader offers extended security which enables us to offer customers an extensive range of services through Online Banking. For more information, please click here.

  • We may text you if we see suspicious activity on your credit or debit card.

    The text will come from +447537414900. This is a number for texting only and it won’t answer if you ring it. We will identify ourselves straight away as ‘First Trust Bank’ and will not ask you for any personal information, account numbers or PIN numbers. You may be asked to confirm whether or not you made a transaction with a ‘Y’ or ‘N’ reply. If you are not happy to answer the text, contact us on the number on the back of your card. If you do not have a mobile phone or your phone does not receive text messages, we will try to call you. If we are unable to make contact with you we will send you a letter asking that you contact us.
