We strongly oppose the Unified Attestation initiative and call for app developers supporting privacy, security and freedom on mobile to avoid it. Companies selling phones should not be deciding which operating systems people are allowed to use for apps.

Unified Attestation

Unified Attestation is a free, open-source alternative to Google Play Integrity with offline verification and simple app + server integration.

Google's Play Integrity API is a horrible system enforcing using devices officially licensing Google Mobile Services. It permits those regardless of how many years behind they are on security patches. The solution to this isn't another anti-competitive system based in Europe.
Play Integrity API should be regulated out of existence rather than making another system where companies permit their own products while disallowing others. It shouldn't be legal when Google does it and it shouldn't be legal when Volla and Murena do it either. This is wrong.
Hardware-based attestation has valid use cases including the Auditor app on GrapheneOS for protecting users. The way these companies are using it serves no truly useful purpose beyond giving themselves as unfair advantage while pretending it has something to do with security.
If banks and governments insist on checking devices for security they should define actual standards. It should be possible for any tiny project to be certified at no cost and the standards should be fairly enforced so a mainstream device without current patches is disallowed.
Volla, Murena and iodé sell products with atrocious security. They fail to provide important patches and protections while misleading users with inaccurate claims about privacy and security. That includes setting an inaccurate Android security patch level despite missing patches.
These companies should not have any say over which devices can be used for European banking and government apps. It will reduce competition and reduce security exactly as the Play Integrity API is already doing. The EU should ban using attestation to determine OS compatibility.
Murena and iodé are extremely hostile towards GrapheneOS. They've spent years misleading people about it with inaccurate claims to promote their insecure products. We'll never work with them. Volla, Murena and iodé should have no say in which OS people can use on their devices.
@GrapheneOS Well, I don't know what's going on in your heads, but whether people want to use Murena, Volla, etc., or GrapheneOS, that's up to the users themselves to decide... It's okay if you don't like each other, but making a statement like that is below the belt... As a GrapheneOS user, I feel embarrassed on your behalf... Just because you've teamed up with Motorola doesn't mean you have to be so arrogant... My two cents.
@Pingitux Their products aren't at all what they claim but rather have poor privacy and atrocious security. They feel very threatened by GrapheneOS. Murena and iodé have engaged in many years of attacks on GrapheneOS including personal attacks on our team. They've engaged in absolutely vile fabrications and bullying aimed at directing harassment towards our team. Their communities have relentlessly targeted our team with harassment. You're pushing a false narrative about what's happening.

@Pingitux Here's the founder and CEO of /e/ and Murena linking to harassment content from a neo-nazi conspiracy site targeting our founder with fabrications:

Their founder and CEO has regularly engaged in vile personal attacks on our including spreading harassment content directly from Kiwi Farms.

Debunking lies about GrapheneOS and our team along with providing accurate information countering their false marketing isn't what you claim it is.

@GrapheneOS Okay, they attacked you, told lies, whatever... Honestly, show some class and don't give a damn about their opinion. After all, you have a community behind you that stands by you... You know, let me put it this way: I tell the world that if it annoys me, I don't give a fuck.. You should try that too when someone gets on your nerves. It works wonders ;)
@Pingitux Our community should help us much more than they do with the attacks being perpetrated against GrapheneOS and our team. If that was happening then it wouldn't be causing nearly as much harm and we wouldn't talk about it as much as we wouldn't feel nearly as much pressing need to provide an alternative to their inaccurate and misleading claims.
@GrapheneOS Have you brought it up in the community? That it's getting on your nerves and that you would like more support from the users?
@eskealler Sorry, I don't know the answer; I wasn't given one, and a few posts later I got blocked 😂 ....
@Pingitux I really wonder what is up with their communication. Very strange. Rather quarrelsome.
@eskealler True... well, whatever... it's up to them (the developers of GrapehneOS)... I've got popcorn and time to spare 😂
@Pingitux Es ist doch zu "cringe" für mich. Ich glaub ich hol mir ein Jolla mit Sailfish OS.
@eskealler Jo, solange mein Pixel 8a mit GOS noch mitmacht bleibt es in Betrieb, danach schaue ich mir die Alternativen, Jolla, Murena und Co mal an
