Is it because of your particular bank or is that a general problem?

Welche realistische Alternative gibt es?

Die was?

Dropbear + manual input, but I guess you could do that as a single command somehow. I rarely restart this machine, so copying the PW from my PW manager is acceptable for me.

Modern CPUs have some RAM encryption features, but ultimately you're running on hardware outside your control. Personally, I use full disk encryption (except for /boot) and unlock remotely via SSH, but that only helps against automatic scanning of the storage.

Link?

Sure, but don't expect incredible graphics on a 4k display. It's a handheld after all.

The regular F-Droid client works (but it's even harder to navigate than NewPipe). I shoould probably just try SmartTube, since it has auto-update capability anyway.

Mostly because it's not available in F-Droid.
