Occasionally, it might happen that a bank changes its keys. You will then receive a message about this, where new hash values are also specified. If you mark and update the bank access in the overview, this page appears. Please only click on Accept if the hash values displayed here match the values you received in the message of the bank.
This page also appears if you have entered the hash values that you obtained from the bank, incorrectly when setting up a new bank connection. See the section New bank connection for this.
