What Is the Titan M2 Security Chip?
Google’s dedicated hardware security chip on Pixel 6 and later — and how it affects repairs.
Definition: The Titan M2 is Google’s dedicated hardware security chip on Pixel 6 and later. It is a separate processor from the Tensor chip that manages secure boot verification, fingerprint data storage, encryption keys, and Android’s verified boot process. It is the equivalent of Apple’s Secure Enclave.
Why it matters for repairs
The Titan M2 enforces Google’s verified boot chain — every time the Pixel starts, it checks that the bootloader, kernel, and Android image are all verified and unmodified. If physical board damage affects the Titan M2’s connections or the boot verification path, the phone may enter a state where it cannot complete startup regardless of software restore attempts. Additionally, the Titan M2 stores the fingerprint data for Pixel’s under-display fingerprint sensor — damage to the chip means fingerprint authentication data is permanently lost.
Titan M2 vs Apple Secure Enclave
Apple’s Secure Enclave is integrated into the main A-series SoC. Google’s Titan M2 is a completely separate chip — physically isolated from the Tensor processor. This gives it stronger tamper resistance but also means two distinct chips can independently fail. In practice, Titan M2 failures are rare and usually associated with major physical board damage rather than standalone chip failure.
