Does anyone have this issue when trying to connect a BMO bank account in QBO: I only have User ID and PW but no Customer ID?

When I'm connecting to my bank account online, I only enter my card number and PW. QBO is asking me for Customer ID (which I don't have), User ID (which I assume is my card number) and password (the same as I use to connect online). I tried to leave Customer ID field blank but it's not working.
