We sell Pixel phones with GrapheneOS as an option. But if you buy one of our phones, how do you know we aren’t secretly loading them chock full o’ spyware?
GrapheneOS comes with an app which allows you to verify the integrity of the OS. The process is very simple:
-
visit attestation.app from a separate device (such as your computer or another phone) and create an account
-
open the Auditor app on your GrapheneOS phone
-
click on the menu and then ‘Enable Remote Verification’
-
scan the QR code displayed on the website with your phone
-
enter an email address to receive an alert if your phone fails to provide attestation (i.e. if the OS is compromised)
-
refresh the site to view the initial result
Enjoy your new secure GrapheneOS installation!
