This is pretty much the way a Yubikey or other 2FA token works, no? The only difference being that it doesn't send the text until the sensor is covered.

- paxswill 7y agoIt's one way a Yubikey can work: Yubikey one time password (OTP). The more common (I think? Newer and standardized at least) way (U2F) accesses the key over some other method that doesn't have it act like a keyboard. There are other operation modes for Yubikeys, but personally I only use U2F and the CCID (aka act like a smartcard) modes.
