Two-factor authentication

Your contact details need to be up to date

We use two-factor authentication to verify it's you when you use online banking (making a payment to someone new for example) or make purchases with your card online. It's the banking industry's way of double-checking it's really you.

Strong Customer Authentication (SCA) has been introduced to help protect you against fraud and make banking safer. We have changed how you verify yourself in online banking to meet this regulatory requirement. We are also making changes to how you make card purchases online but these will come a little later.

So you can use online banking and make purchases with your card online in the future, your contact details need to be up to date.

How it affects you

online banking icon

When you use online banking

We have replaced card readers with a different way to verify yourself. We've also increased security when you view statements, transactions, scheduled payments and sometimes when you log in.

Don't worry though, your existing login details haven't changed.

When you use your card online

To complete your purchase, you'll verify yourself in a different way and probably more often.

This is so we know it's really you making the payment.


How you can verify it's you

  • Online banking
  • Shopping online

When using online banking, you'll verify yourself with a verification code we'll send to you by text message or email.

We'll send a verification code to the UK mobile number or email address you have registered with us when you:

  • Make new payments
  • Make international payments
  • Create and manage standing orders
  • Update your contact details
  • Re-set your online banking password and/or 6-digit security code

And, to help further protect you from fraud, we'll also occasionally send you a verification code when you:

  • Log in to online banking
  • View statements and transactions
  • View or cancel Direct Debits

You'll need to enter your verification code along with your password and 6-digit security code to confirm it's you. It's important that you never tell anyone your verification code.

When shopping with your card online you will receive a verification code by text message and be asked for your memorable name, which you currently use when making online card purchases.

We will send a verification code to the UK mobile number you have registered with us. You'll use your code and your memorable name when shopping online to confirm it's you.

The changes won't be happening just yet. We will let you know nearer the time how this will impact you if you don't have a mobile phone. Until we notify you, you can use your card to make purchases online as you do normally.
