No. Accountable does not access nor store any banking credentials.
As of 2019, all access to bank accounts, except for ING, is managed by our partner Budget Insight (https://www.budget-insight.com/). Budget Insight is a company based in France which, under the European PSD2 directive, is a regulated payment institution approved by the French Prudential Supervision and Resolution Authority (ACPR) as a Third Party Provider (AISP and PISP). More information on their security protocols can be found here (https://www.budget-insight.com/security).
Access to ING account is done based on the signature of a paper mandate sent directly to ING, so no bank credentials are stored.
