Roblox Officially Supports GrapheneOS for Android Remote Attestation

Overview

Roblox has added explicit support for GrapheneOS as a trusted operating system for its Android remote attestation checks. This means that devices running GrapheneOS with a locked bootloader can pass the integrity verification required by some Roblox games.

What is Remote Attestation

Remote attestation is a security check that Roblox uses in certain games to confirm that a player is on a real, physical device and that the Roblox app has not been modified. If the check fails, the game may display messages such as "This place has enabled additional hardware security requirements" or "Roblox was not able to verify the integrity of the game" and can block access to protect other players from cheats.

Why GrapheneOS is Supported

According to Roblox’s FAQ, GrapheneOS is currently supported when the bootloader is locked. Support for other third‑party ROMs is possible if they:

• Do not break the AOSP security model,
• Support installation with a locked bootloader,
• Properly configure and publish self‑signed verified boot keys for their ROM,
• Promptly update to the latest AOSP patch level. If a ROM fails to meet these criteria, Roblox may remove it from the set of supported verified boot keys.

How to Verify Support

Users can check whether their device passes the attestation by attempting to join a game that has enabled the stricter security requirement. If the game loads without showing an integrity error, the device is considered supported. Roblox recommends updating or reinstalling the app from an official source, keeping the Android OS up to date, and ensuring the bootloader remains locked.

Limitations and Considerations

• Remote attestation is enforced per‑game; creators decide whether and how strictly to use it.
• Games that do not require the check can still be played on any device, including those that fail attestation.
• The feature is designed to prevent cheat clients, emulators, and modified apps from pretending to be legitimate devices, so Roblox cannot override the requirement for specific devices.
• Amazon Fire devices are not expected to be supported.

Community Reaction

Comments on the Hacker News post highlighted the significance of the announcement:

"This is a really interesting signal tbh. While it sounds like it already works on GrapheneOS having a corporation come out and say they won’t go out of their way to break it is quite unusual." — @dugite-code

"Makes sense for them to support this given their scale. I wouldn’t be surprised if GrapheneOS secures another big Android OEM vendor (after Motorola Mobility) and the user base of the OS quickly grows from its current 400k+ to millions." — @jordand

"Truth be told, GrapheneOS is the only third party ROM that bothers to make app attestation work." — @AppAttestationz

"Great news! I never had problems running Roblox on my GOS, but it’s nice to see the explicit, official support. Snowball effect (for both sides, software publishers and OS vendors)." — @subscribed

Some users expressed concerns about device freedom:

"Don’t get too excited, this still goes against the basic freedom to own the devices you’ve paid for. Remote attestation is still there and only official builds of GrapheneOS are supported. While this is marginally better than being tied to a build from an advertising company, you’re still out of luck if you want to build the OS yourself." — @m132

Others noted limitations for alternative ROMs:

"However, if on LineageOS, which mind you is the only way to get updated (and thus safer) android versions in many devices, they simply block you. Awful." — @snvzz

The overall sentiment is that Roblox’s explicit endorsement of GrapheneOS is a notable step for privacy‑focused Android users who wish to retain access to games that rely on hardware‑based integrity checks.
