People need banking and payment apps to work on Linux mobile for it to work. Obviously the only real "fix" for this is a regulatory one that declares SafetyNet a monopolistic control mechanism, which it is. But also, with fintech stuff getting easier and easier, I wonder if creating at least an open _banking_ app should be possible. Yes, various countries require push-based 2FA, but nothing locks you into Google/Apple here on Linux. I wonder how the payments situation would be ...

@pojntfx My understanding is that TOTP is not sufficient for 2FA because PSD2 SCA requires that for online payments, the authentication must be dynamically linked to the transaction's specific amount and payee. But maybe a standard JWT minting process could be enough (send request to the app, app signs the request with a private key potentially via TPM2, send the signed request back).
