I've been with HSBC for over 10 years and never experienced any problems even though I'm fairly allergic to dumb UX. I use the iOS app which has 2FA (touch id) to do everything. Last time I logged in via a web browser was years ago, I can't even remember the interface. I can't quite agree with you as I think more security layers are better when it comes to your personal bank account.

With that said HSBC is not the best retail bank as individuals were never their primary target base. I've had a few problems with them but only when dealing with branch personnel. For anyone in the UK wanting to move away from HSBC but don't know where, look at First Direct. It's a retail bank owned by HSBC group but it's been consistently voted among top three banks every year by customers.
