unfortunately you lose access to pretty much ever banking app :/

This is a popular thing to say, but is an oversimplification...

Call it anec-data but all my banking apps work in GrapheneOS, and I have several installed. There is one that reduces functionality if SafetyNet fails (have to do the 2fa flow every time I restart the app, can't set as a trusted device and notifications don't work) but it still works to access my account.

That said... I haven't tried to use NFC payments and do carry around a secondary iPhone 15 as my "business phone" these days that pretty much just has payment/banking apps on it, just in case one bank or another decides to suddenly nuke their app on my main phone...

		After I got the screen replaced on my previous phone the fingerprint reader didn't show up, and I didn't bother to try fixing it. I hadn't specifically requested a new panel with fingerprint reader, but supposedly it could be enabled, if available, through tools Google provides for Pixels with their Tensor chips. Apps that would otherwise use the biometric authentication can fall back to a pin or pattern, but all of my banking or work benefit-related apps will not save credentials in that case, so I have to rely on my password manager which will use the PIN/pattern for authentication. I replaced that phone with a new one and didn't bother setting up the fingerprints. It doesn't seem to bother me too much and maybe there's some small security benefit to not having the biometric authentication enabled.

		My bank doesn't even allow me to have USB debugging enabled

Not necessarily, I have quite a few that work.

It's crowdsourced and therefore incomplete but https://plexus.techlore.tech/ has reports of compatability with the complete absence of Google Services or a replacement like MicroG.

Here in Switzerland my experience is that the big banks like UBS and the cantonal banks tend to work, while the smaller things like McDonald's and my credit card providers tend to break because they have nonsense Play Integrity requirements.

There are different levels of anti-user checks. Some only detect unlocked bootloader and/or root. Others use the play integrity anti-feature provided by Google. GrapheneOS tells you when apps request play integrity checks, and you'll see that a lot of apps do these requests constantly, even if they don't actually block you for using an unlocked or non-vendor system (custom key but otherwise locked and not rooted like GOS).

We really need a more foolproof technical solution for this if general purpose computing on the mobile phone is to be preserved. Perhaps some type of a remote control scheme to operate on a "slave" device. Failing that, if I do need one of such apps needing "strong" integrity, I'd probably look into getting an iPhone for those.

I haven't come across a banking app in the UK that doesn't work with GrapheneOS. HSBC insists you use the AOSP or Google keyboards but otherwise no issues.

I use GraphaneOS and have had zero issues with the ~10 bank/brokerage apps I use.

Can you use NFC payment?

Not with Google Wallet.

... What are you using instead and is it as easily triggerable by some shortcut?

FWIW, I use Fidesmo. Oversimplified, it allows you to copy your credit card's NFC chip into an accessory you wear. I use a ring but there are other options like bracelets or watch bands. No batteries, no devices, no wireless connectivity. It works anywhere an NFC card works, which here in Switzerland is more or less everywhere.

It requires that the card issuer support Fidesmo though. Many here do but I'm not sure what it's like elsewhere.

I personally use my smart watch for NFC payments. I find it far more convenient then paying with my phone.

> I personally use my smart watch for NFC payments

But not Google Wallet, and with GrapheneOS as the connected device?

		Yes, I have a Garmin watch paired with GrapheneOS.

The experience varies by country, here in Finland I haven't had a single banking app complain about an unlocked bootloader or a custom OS.

Every banking app works perfectly for me on GrapheneOS.
