So, uh, the next version of GrapheneOS will probably come with some Android OS version spoofing tech that solves this - if there isn't something on F-Droid already.

much thanks to @gary_host_laptop for the logo design :)
No it won't. Or at least they said on BlueSky that if there had been a work around for this they would have solved it already.
Can Graphene add a feature to run in emulation mode to allow apps to believe it's on an unrestricted OS?
Unfortunately, this is probably because of the apps started using the Play Integrity API, which is a hardware-based attestation and can only be faked in two ways that GrapheneOS isn't interested in:
- you can fake an older device that didn't support hardware attestation yet, or had a broken implementation
- or you can try getting leaked vendor keys and emulate the crypto with those until they get revoked
Lol I spent a week going back and forth with Revolut support in august. I could sign into the app but it would always ask me for a "selfie" verification and every time support would say its a super dark selfie.
Eventually I decided to try a stock ROM and it just worked and I realised what was happening so I transferred all of my money out and deleted my account.
Most local banks here are terrible at making apps, some even require a separate device that looks like a calculator to use online banking, so hopefully they wont follow suit anytime soon

To be fair this actually provides a very high level of security? At least in my experience with AIB (in Ireland) you needed to enter the amount of the transactions and some other core details (maybe part of the recipient's account number? can't quite recall). Then you entered your PIN. This signed the transaction which provides very strong verification that you (via the PIN) authorize the specific transaction via a trusted device that is very unlikely to be compromised (unless you give someone physical access to it).
It is obviously quite inconvenient. But provides a huge level of security. Unlike this Safety Net crap which is currently quite easy to bypass.
Those little boxes are just a bit of hardware to let the smartchip on the smartcard do what's called challenge-response authentication (in simple terms: get big long number, encode it with the key inside the smartchip, send encoded number out).
(Note that there are variants of the process were things like the amount of a transfer is added by the user to the input "big long number").
That mechanism is the safest authentication method of all because the authentication key inside the smartchip in the bank card never leaves it and even the user PIN never gets provided to anything but that smartchip.
That means it can't be eavesdropped over the network, nor can it be captured in the user's PC (for example by a keylogger), so even people who execute files received on their e-mails or install any random software from the Internet on their PCs are safe from having their bank account authentication data captured by an attacker.
The far more common ~~two-way-authentication~~ edit: two-channel-authentication, aka two-factor-autentication (log in with a password, then get a number via SMS and enter it on the website to finalize authentication), whilst more secure that just username+password isn't anywhere as safe as the method described above since GSM has security weaknesses and there are ways to redirected SMS messages to other devices.
(Source: amongst other things I worked in Smart Card Issuance software some years ago).
It's funny that the original poster of this thread actually refuses to work with some banks because of them having the best and most secure bank access authentication in the industry, as it's slightly inconvenient. Just another example of how, as it's said in that domain, "users are the weakest link in IT Security".
Banks seem to be hit or miss, happy that mine works. Would rather switch Banks than use a stock Rom, though.
All the Uber stuff works in Browser, both eats and their fake taxi stuff.
Not having a subtle reminder to eat at McDonald's is probably better for you.
Honestly, if your app could be a website, and includes services not on your website, fuck you, I'm gonna go to the competition.
man, and i was gonna switch to graphene this christmas. if every app can just ban my OS, i might have to rethink this. i would use the website but they restrict so many things to apps now…
I was about to switch bank because for a few days my current one (inadvertently) blocked it on grapheneOS. We sent them a few emails and they fixed in less than a week.
TBF, this is the first time I've encountered an app not working - and it was before this. It's just because of Google push towards monopoly via their Play Integrity API that's ruining this.
play "integrity" should be considered malware, any program that deliberately does something the user doesn't want it to should.
Use the websites whenever you can. That's what I do at least. Although I had to stop using Lyft entirely, because they stopped supporting rides from their website apparently. And that leaves just Uber. I actually left my bank for a similar reason. It supported my phone just fine, and it worked without Google Play Services, but the website wouldn't let me do everything that the app would, and the app required that I have Aurora Store to download their banking app from the Google Play Store, and I wanted to get away from that, so I switched banks so that I could use the bank website instead. From what I can tell, you run into this kind of stuff a lot with FinTech apps. But if you use older banks, like Discover or Wells Fargo or things like that, they tend to work better. Maybe because they're not up with the newest technology, LOL.
Yeah Revolut is also the kinda app that is almost only a mobile app, not much you can do with their website, last i checked.
Well that's bad. I've been using revolut for years now.
Does anyone have a suggestion for a new bank that's operating under european law?
Authy has been utter garbage for a long time and if you ever needed a reason to migrate away then now is as good as ever.
Their loss.
If a business makes it too difficult to use them I just use someone else. I'm sure they understand that but are making a killing at the expense of other people.
Would not updating Revolut keep the app compatible as long as you don't sign out?
If so, don't update the app and write down the build number of the last app version which worked on GrapheneOS. That way you would have a bit more time to sort things out.
They constantly force you to update or the app won't work. I was already having issues with Revolut on GrapheneOS so I just closed my account and switched to Wise. The Revolut app was a bloated mess anyway.
Google has ruined Android by closing it up.
EU needs to step in and force Google to open it up.
While at it, go for Apple's monopoly as well.
Revolut seems to continue working as of now on my PIxel 7. I'm transferring the money out just in case. Any idea when are they going to stop them from working?
Stops working if you log in and out of your account. At least this is what GrapheneOS folks stated on BlueSky.
Can I simulate another OS environment for these kind of apps?
