And for good reason. It's the operating system that should offer a 'certified secure' keyboard if the app requests it though. A bit like Windows' account password entry screen that is sandboxed from the rest of the OS (if I understood it correctly).

In this case, the app has its own keypad when logging in so I'm not sure what the added value is security-wise.

I'm just not able to launch the app while an F-Droid keyboard is set as default which is just annoying. There's many keyboards on the Play Store that I wouldn't trust to install and use.
