But we don't have anything like FF as an alternative to go from Android. Especially considering banks require "certified OS".
I also switched banks so I can use my bank card as the 2FA device, similar to CAP. [0]

1) an old iPhone with 0 personal data on it and in no way linked to my identity, which is used for completely untrustable commercial apps, and rarely even leaves the house.
2) a LineageOS Android which is my daily smartphone for things like camera and GPS, running almost exclusively open source apps, except for unavoidables like WhatsApp which are run in an separate profile
3) a GPD Micro PC running Void Linux, which is roughly the same size as the phone and a true swiss army knife. Its purpose is to reliably do what I want, when I want it. No systemd, for it does not spark joy. It is used for web browsing, note taking, light productivity, and playing movies on the TVs of friends who have overinvested in streaming and dongles only to find that $CHOSEN_MOVIE is not on any of their services.
I am not entirely happy with this state of affairs - too many devices, and still not enough siloing of closed apps like WhatsApp.
