Following changes to the law in 2018, you can allow an authorised Third Party Provider (TPP) to have access to your online account. These TPPs, sometimes known as Account Information Service Providers, offer functions such as being able to view all your bank and credit accounts from a single app or website. You can only use a TPP once you have registered for Online Account Manager with us. We will then give the TPP access to your account information only. They will be able to see your recent transactions and outstanding balance, but they will not be permitted to change any of your preferences or Direct Debit information.While it is generally not advised you give anyone your security details used for logging in, a TPP may ask for them if it is necessary. All TPPs must be authorised or registered with the Financial Conduct Authority (or another EEA regulator), so you must check that it is permitted by law to provide you with the expected services. The TPP should also agree with you that any sensitive or security details you provide will be stored securely and only used for the purposes you authorise.If you give your security details to an unauthorised TPP, we will assume it is you authorising us to allow access to your account. If we become aware that an unauthorised third party is using your security details, we will block access to your account.
