With the Pixel 6 series, Google began developing its in-house Tensor SoC. But that wasn’t the first time the search giant used a piece of custom silicon in its smartphones – the Pixel 2’s Pixel Visual Core was technically the first. One generation later, the company announced that Pixel 3 devices would include a hardware security module dubbed Titan M. Then, in 2021, Google followed it up with the Titan M2. The security chip has since become a selling point for Google phones like the Pixel 7 series and Pixel 6a.
So in this article, let’s take a closer look at the role of the Titan M2 in Pixel devices, how it works, and why it’s even necessary in the first place.
