Glad to have you as part of this discussion, @tkoni,
I hear you and can understand the frustration of not having this function as expected. At the moment, QuickBooks only accepts up to 12 characters for financial institution passwords.

Once done, establish the connection again in the Banking page through these steps:
To avoid any errors in the future validate the credentials in the bank website then use it when signing in to online banking.
If the same issue happens after updating the password, I highly recommend contacting our Support Team to create an investigation for the problem. Here's how to get support:
I appreciate your time today. Please know that the Community has your back and I'm here if you need additional guidance with anything in QuickBooks. Wishing you all the best! Have a lovely day!
