Improved online security

We're introducing smarter, stronger and safer ways to keep you protected online

What's changing?

Soon we will ask you to confirm your identity more often when using online banking or when you buy something online with your card. It'll provide extra protection against fraud and scams by ensuring it's you who is using your details, and not someone pretending to be you.

You’ll notice that when you buy something online we’ll sometimes send a code to your mobile phone or email address if we don’t have your mobile number. This code is called a One Time Passcode (OTP) and you’ll need it to authorise your card transaction.

When you use online banking, we may occasionally send a One Time Passcode to your mobile phone to verify it’s really you (alternatively you will have the option to use your card reader instead of the code).

So it’s really important that we have the correct mobile number for you.

Why is it changing?

Fraudsters and scammers are becoming more clever and sophisticated. It's our job to keep one step ahead, and to keep your money safe.

We're continually investing in new technology for extra security - and that's why we're introducing a number of new changes to keep you secure.

It's really important that we have the correct mobile number for your account. If we don't, we won’t be able to send you a passcode and you might not be able to access your account or use your card online. We also won't be able to alert you if we see any suspicious activity on your account.
