Read-only access, provided by an account information service provider, lets a third party view balances and transaction history but cannot initiate payments.

Its security rests on encryption, Strong Customer Authentication, regulated access and standardised APIs, though you should still vet the provider and revoke access when you no longer need it. Read-only access lets a provider view balances and transactions but cannot initiate a payment. Consent under the UK's PSD2-derived rules is time-limited, so you should re-approve rather than assume it rolls on. Open banking never stores your bank login details, unlike screen scraping which keeps your password and PIN. Most UK banks let you revoke open banking access in the app without contacting anyone. Revoking a consent does not delete data the provider already holds, so ask it to delete your data.
