Google today effectively simplified its lineup of Titan 2FA hardware keys to just two types of keys: USB A and USB C, effectively dropping BlueTooth connectivity. Both of the keys fully support Near Field Communication Functionality (NFC). This NFC functionality makes it compatible with the majority of mobile devices by simply tapping the mobile phone for a secure log in. Availablity for the new keys starts tomorrow August 10, 2021.
