Validate device security with hardware-based integrity and identity verification

Features & Capabilities

Auditor is a Chrome extension designed to enhance your device security by leveraging hardware-based integrity and identity verification. It enables users to validate the operating system's integrity remotely from another Android device, confirming that the device runs the official stock OS with a locked bootloader and no unauthorized tampering. The system also detects OS downgrades, providing an added layer of trust.

Supported devices use a Trusted Execution Environment (TEE) or Hardware Security Module (HSM) to send signed device information, ensuring that the verification process cannot be bypassed by OS modifications. Auditor primarily relies on a Trust On First Use mechanism, improving its verification capabilities after initial pairing through pinning and identity validation. Comprehensive tutorials and documentation are available to guide users through setup and usage, making Auditor a powerful tool for maintaining robust device security.

User Reviews

Auditor is praised for its simplicity, effectiveness, and privacy-focused design, making it highly recommended for verifying device integrity especially on GrapheneOS and Pixel devices. Users appreciate its lack of ads and trackers. However, it faces issues on some devices like the Galaxy A05, difficulties scanning complex QR codes, and lacks integrated documentation and clear menu option labels, which could improve user experience.

Pros

Simple and effective design that works as expected
Highly recommended for checking device integrity and security
Excellent for users concerned about device security and verifying unmodified OS
No trackers or ads, enhancing user trust and privacy
Works well on compatible devices, especially GrapheneOS and Pixel phones

Cons

Does not work on certain devices like Android Galaxy A05
Difficulty scanning complex QR codes
Lack of in-app documentation; documentation is hosted externally
No in-app indication of when the last remote attestation was sent
Option names in the menu are not immediately clear regarding their purpose

Recent reviews

I'm not going to pretend to understand exactly how this works, but the developer's documentation on the tech is really interesting. I like that the app actually looks pretty nice. My only nitpicks are that the great documentation is not inside the app, but on an external site; there is no screen that shows when the last remote attestation was sent; and that names of most of the options in the three dot menu don't make immediately obvious what they do for your threat model.
