FEITIAN MultiPass K25 USB Security Key - FIDO2 + FIDO U2F - Two Factor Authenticator with USB-A, NFC, Bluetooth - Help Prevent Account Takeovers with Multi-Factor Authentication

I bought the previous gen MultiPass (basically the Google Titan USB/NFC/BLE key). That is an all plastic shell. As others have said and shown, the cases have cracked and fallen apart, especially if kept on a ring with keys. So I've kept mine on my spare key ring that pretty much just sits in my glovebox and use it as needed.The K25 has a metal ring around the entire perimeter and what looks to be a crimped key ring hole. Very nice. This will be going on my primary key ring and carried every day. I expect it will hold up just fine. I've registered it on a dozen accounts and so far no issues with USB via PCs and phone, plus NFC and BT via phone. Basically the same as the old one in a much better case.

Nice and sturdy which means it should stand the test of time. however, Bluetooth function does not work with windows and you have to connect with USB, but you need this or a Bluetooth security key to use google highest authentication. sad. and oh, my packaging came not tightly sealed...

It isn’t made clear at all that Bluetooth completely 100% does not work at all on macOS. It comes with a mini usb to USB-A which of course doesn’t work on any modern Mac.For iOS you need Google Smart Lock app which is the worst buggiest app I think I have ever used. I was never able to pair my device using it. There are multiple screens in the app where you get stuck forever and can’t go back. You have to force kill the app and start over. Yes really.Don’t buy this device if you own any Mac devices.
