# Account servicing payment service provider

> The provider that provides and maintains the payer's payment account, typically the customer's bank.

Under PSD2, an account servicing payment service provider, or ASPSP, is a payment service provider providing and maintaining a payment account for a payer, typically the customer's bank. In open banking it is the party that must give authorised third parties secure access to the account and that authenticates the customer. For agentic payments it is the last line of control, because it executes the payment and can check authentication, limits and fraud signals before money leaves the account.
