I have received the PCBs for the prototype device and soldered one of them.
I have started with the design of the first prototype device featuring ESP32 PICO D4 microcontroller and ATECC508a security chip.
I have ordered two fingerprint sensor modules capable to perform the biometric user validation
During last two weeks I've achieved some progress with WebAuthN implementation.
Last weekend I was playing with ESP32 development board to implement FIDO2 endpoints. I have achieved some success - the Chrome can detect the device and tries to connect to it for the authentication.
Some time ago I was reading news and met a very interesting topic - passwordless authentication. The idea is great: instead of remembering multiple passwords for the different websites one could use special device called Authenticator
