Some banks are phasing out code cards or SMS verification for 2FA, and the only way to get the second factor for logging into the online banking website on your computer, is to use the bank’s app on your phone.
Obviously other solutions could be implemented if the bank chose. But if the bank does not choose to implement those other options, and instead requires the use of their app, then that explains for the OP’s sake some of the interest in running the bank’s app instead of solely using the website.
