In a recent update to the HSBC app they’ve added a screen to prevent you from using the app unless you use the default (google) keyboard.
They do a similar thing if you have an accessibility service running that can access the screens content. A fair enough security warning if you’ve happened to install a dodgy keyboard app, but highly frustrating when using an open source alternative that enhances the security and privacy over the default option (HeliBoard in my case).
I haven’t found a way to circumvent the page yet. It would be useful if Android allowed you to block the permission to query all packages, but alas.
banks will do everything in their power to restrict who can use their services in the name of security but are absolutely fine with 6-char password size limits and SMS 2FA
They are in an illusion where their backend is absolutely perfect, but third party apps like open source keyboards implement spyware that spies on users predictable bank passwords. (FlorisBoard is the biggest predator)
