This sounds cool, can we import our google authenticator keys to this authenticator dongle and vice versa? do you have a video on how to use this and what is the price range just curious. If its really affordable and flexible for sure I am gonna buy it, thanks for the info.
If you mean TOTP based key then the answer is nope. But Google has the option to bring to bear U2F protocol and utilize the HW keys like Yubico to authenticate you. It works in following way. When you register you HW-key-dongle at Google it sends the random number to that dongle. Based on that number the last generates private - public keys pair. Then the public key of that pair is send back to Google that assigns it to your ID. Next time when you log in to Google it sends to HW-key the message and waits for outgoing one that must be signed by HW-key using the corresponding private key. After receiving encrypted message Google decrypts it with public key and checks. If everything is correct then you are in.
P.S. I'm using Yubikey5 to log in to my bitcointalk forum account. But this is the other story.
Unlike TOTP with U2F you don't have to share a seed with the server, so it doesn't need to store it and to send it to you, and you don't have to send any symmetric code.
