According to this list both of my banks (CAF and The Co-operative) offer a connection using SCA.  For both, it says: "Bank connection is available using Strong Customer Authentication (SCA). You will need to enter your user ID and password when you update new transactions."

But on QuickBooks Online if I try to make a connection it says, "Banking regulation changes have impacted your [bank] connection. To keep those transactions updated, use QuickBooks on the web to upload data with a file from your bank."

So which is true?
