On BNP Paribas and Hello Bank it is mandatory to renew your password every 100 connections. Each Bankin' sync counts as one connection.
We have worked on a solution allowing you to change the password directly from the application:
➡️In Bankin' app, renew your bank password via your bank interface
➡️ Validate to start syncs
If it does not work:
➡️Go to your bank website and renew your password
➡️In Bankin' app, click Menu> Settings> Bank Accounts> BNP Paribas / Hello Bank
➡️Go to the bottom of the page> Edit your ID > edit your username and password.
