When the end-user selects an Open Banking provider from our Auth Dialog, they will be redirected to the bank's website. The consent journey on the bank's website will allow the customer to select what accounts they want to share with the 3rd party.
Once the user has given consent to access the data, they will eventually be redirected back to your application and you will be given a code that you can exchange for a token.
No credentials are shared with TrueLayer or the 3rd party.
