    No lol, they have a list of specific hardware security requirements for a device to have, the biggest one being a secure element. Without a secure element there is no hardware-backed key derivation throttling, so it’s much more possible for an attacker to brute force your phone’s PIN.

    Support for using alternate operating systems including full hardware security functionality
    Complete monthly Android Security Bulletin patches without any regular delays longer than a week for device support code (firmware, drivers and HALs)
    At least 5 years of updates from launch for device support code with phones (Pixels now have 7) and 7 years with tablets
    Device support code updated to new monthly, quarterly and yearly releases of AOSP within several months to provide new security improvements (Pixels receive these in the month they're released)
    Linux 6.1, 6.6 or 6.12 Generic Kernel Image (GKI) support
    Hardware accelerated virtualization usable by GrapheneOS (ideally pKVM to match Pixels but another usable implementation may be acceptable)
    Hardware memory tagging (ARM MTE or equivalent)
    Hardware-based coarse grained Control Flow Integrity (CFI) for baseline coverage where type-based CFI isn't used or can't be deployed (BTI/PAC, CET IBT or equivalent)
    PXN, SMEP or equivalent
    PAN, SMAP or equivalent
    Isolated radios (cellular, Wi-Fi, Bluetooth, NFC, etc.), GPU, SSD, media encode / decode, image processor and other components
    Support for A/B updates of both the firmware and OS images with automatic rollback if the initial boot fails one or more times
    Verified boot with rollback protection for firmware
    Verified boot with rollback protection for the OS (Android Verified Boot)
    Verified boot key fingerprint for yellow boot state displayed with a secure hash (non-truncated SHA-256 or better)
    StrongBox keystore provided by secure element
    Hardware key attestation support for the StrongBox keystore
    Attest key support for hardware key attestation to provide pinning support
    Weaver disk encryption key derivation throttling provided by secure element
    Insider attack resistance for updates to the secure element (Owner user authentication required before updates are accepted)
    Inline disk encryption acceleration with wrapped key support
    64-bit-only device support code
    Wi-Fi anonymity support including MAC address randomization, probe sequence number randomization and no other leaked identifiers
    Support for disabling USB data and also USB as a whole at a hardware level in the USB controller
    Reset attack mitigation for firmware-based boot modes such as fastboot mode zeroing memory left over from the OS and delaying opening up attack surface such as USB functionality until that's completed
    Debugging features such as JTAG or serial debugging must be inaccessible while the device is locked
    
    

    Until the collaboration with Motorola produces a device, only the recent Pixels meet the requirements.

    Fairphone is also one of the worse OEM’s when it comes to how slowly they patch and releases security vulnerabilities, and they are known to be quite sloppy, in the past they have published their private keys. I wouldn’t trust keeping anything remotely private or sensitive on a Fairphone.
