Connect bank uses an EU law called PSD2 (Payment Service Directive 2). The law requires banks to make their customers' data available via an API (Application Programming Interface) which enables a third party (approved banks and credit institutions such as Lunar) to process their customers' data with users' approval. Lunar leverages these APIs to allow you to access your other accounts with another bank within the Lunar app.

You can access payment accounts (typically your salary account), but not special savings accounts such as a child savings account, depots or the like.
