Strong Customer Authentication

At Principality, we're committed to making sure you stay safe when using our online services

All UK banks and building societies will be carrying out extra security checks to help keep you safe when managing your finances online.

It’s called Strong Customer Authentication, or SCA for short. SCA is designed to help us all fight fraud and improve the security of online payments.

The process, to make sure it’s really you, is known as two-factor authentication. Two of three categories below must be used to do this.

Principality’s SCA solution on our online service Your Account will use the first two of the three categories when you log in and when you move money to your linked account:

  • Something you know e.g. password, which Your Account customers already have
  • Something you have e.g. mobile phone. Many Your Account customers have already provided their mobile number. As part of the new Your Account login, we’ll send a passcode to your mobile, so it’s important we’ve got the right number and that it’s unique to you.
  • Something you are e.g. fingerprint.

If we don't have your mobile number

When we launch the new Your Account, if we don't have your mobile number, we can't send you a pass-code and you won't be able to log in.

Frequently Asked Questions

When are we introducing the changes?

The changes will be introduced when we launch the new and improved Your Account.

If you’re registered for our online service, we’ll send you more details on the new Your Account, including the launch date, later in the year.

Who does this affect?

If you’re a Principality customer registered for our online service Your Account, we’ll need your current mobile number.

We’ll be in touch to ask you to provide your current mobile or check that the number we have for you is correct.

Before the new Your Account is launched, if you haven’t already responded to our request via email or letter you can send us a secure message using Your Account to update your mobile number. You can also call us, write to us or pop into a local branch.

After the new Your Account is launched, you can call us.

Once we have your current mobile number, you’re all set up.

How do I check if you have my correct mobile number?

  • Log into Your Account
  • Click on the Your Personal Details tab
  • If you have added a mobile number this will appear here, if the number is correct you can leave it as it is
  • If the number that appears is incorrect, or you have not added a mobile number you can do so by clicking on Secure Message and sending a message saying ‘My number is 07XXXXXXXXX’
  • If you have any problems please give us a call

What if you don’t have a mobile number or a mobile signal?

If you don't have a mobile number or haven't got a mobile signal, you won't be able to log into the new Your Account. Don't worry though:

  • If you have an online only account, you can call us to continue to manage your account.
  • If you have another type of account, you can also visit a local branch or post a request to us.

What if you’re not registered for Your Account?

Whilst it’s important for us to have your current details, you don’t need to do anything now.

If you decide to register for Your Account later, we’ll need your current mobile number and an email address that is unique to you.
