I do have one bank account where I need the SecureGo Plus app for 2FA. I’ve now found a way to use it by means of waydroid on my Linux notebook. In waydroid, I use Aurora that I got via F-droid. Currently only version 4.2.5 is working that can be installed by enabling the F-droid Archive repos. Based on Aurora, I could then install the SecureGo Plus app.
Does your SecureGo Plus app not complain about the absence of Google Play services? biometric authentication? screen lock?
Or does Waydroid have GAPPS (or can install them…)?
I use VRsecureGo plus and its running without any problem on Xperia 10 II
