Verify your device
Don't trust us. Check the signature.
We ship official, unmodified GrapheneOS — nothing patched, nothing swapped. Every device we sell has its Verified Boot fingerprint published below. You can confirm it yourself, against our table and against the GrapheneOS project's own values.
What it means
Hardware-level proof on every boot.
Every Google Pixel contains a Titan security chip. When you power on the phone, Titan checks a cryptographic signature of the entire operating system against a known-good fingerprint stored in hardware. If anything has been altered — even a single bit — the phone refuses to boot.
We install GrapheneOS and re-lock the bootloader before shipping. That means Titan's Verified Boot is fully active — the phone is checking the OS on every single power-on.
The fingerprint shown on your boot screen is the SHA-256 hash of the OS signing key. Compare it to our published values — and to GrapheneOS's own — and you have independent, hardware-attested proof that the phone is running exactly what we say it's running.
How to check
Under two minutes.
01
Open Settings on your phone
Navigate to Settings → About Phone → Verified boot state. You'll see "Boot verified" and a fingerprint.
02
Compare to the table below
Find your device model in the table. The fingerprint on your phone should match exactly.
03
Cross-check against GrapheneOS
For independent confirmation, compare against the official values at grapheneos.org/install/fingerprints — the source we publish from.
