Future-proof support for multiple standards: We focused on keys supporting the newest set of specifications, such as FIDO2.Security protocols: Since hardware keys are a security item, we dug into each company’s track record on previous recalls and looked at whether the company had a coordinated vulnerability-disclosure program to allow security researchers to report bugs.But most keys are easy to use and relatively inexpensive.

Google said it's discontinuing the Bluetooth model to focus on “easier and more widely available NFC capability'.

It launched in 2018 and will no longer be sold. There's also an older key with NFC, Bluetooth, and USB. The $30 new USB-A key is essentially its upgraded successor that comes with a USB-C adapter.

Google has long sold a USB-A key that already included NFC for $25. Got a Mac with only USB-C ports as well as a phone? The $35 key is for you. Now, it's easier to decide which key to buy - because it simply depends on your device and the kind of ports it offers. Previously, Google's USB-C Titan key, made in collaboration with Yubico, didn’t support the wireless standard. The most significant change is the updated USB-C key now offers NFC support.
