The Titan M2 is a security chip developed by Google for its Pixel smartphones. It enhances device security by protecting sensitive data, such as passwords and biometric information, from unauthorized access. The chip is designed to work alongside the main processor, ensuring that critical security functions are isolated from the operating system. In addition to safeguarding personal information, the Titan M2 supports secure boot processes and helps verify the integrity of the device's software. This means that it can detect any unauthorized changes to the system, providing users with an added layer of protection against potential threats.
