The Titan Security Key is a FIDO-compliant security token developed by Google which contains the Titan M cryptoprocessor which is also developed by Google. It was first released on October 15, 2019.[1]
Features
[edit | edit source]Depending on the features, the key costs $25-$35,[2] but Google has provided them for free to high-risk users.[3] It is considered a more secure form of multi-factor authentication to log in to first-party and third-party services and to enroll in Google's advanced protection program. In 2021, Google removed the Bluetooth model due to concerns about its security and reliability.[2]
In November 2023, Google announced a v2 model passkey with FIDO Authenticator Certification Level 1 support.[4][5]
Vulnerabilities
[edit | edit source]The Bluetooth "T1" and "T2" models initially had a security bug that allowed anyone within 30 feet to make a clone of the key.[6] The security firm NinjaLab has been able to extract the key using a side channel attack.[7] In 2019, Google has put a bug bounty up to US$1.5 million on the Titan chip.[8]
Newer versions and model numbers include:[9]
- USB-A/NFC (K9T)
- Bluetooth/NFC/USB (K13T)
- USB-C/NFC (YT1)
- USB-C/NFC supporting U2F and FIDO2 (K40T)
While none of these included publicly disclosed security vulnerabilities, Google has discontinued selling Bluetooth versions of the keys in August 2021,[10] although Bluetooth keys continue to work with their warranties honored.[11]
