Thank you! I will definitely take a look at your CTAP implementation!

Oh, in fact it's much simpler than MicroUSB. There is special type of USB Type C used for charging - https://en.ovcharov.me/uploads/2020/04/06/20200404_092055.jp... It has only six…

Nothing can stop us from making the same PCB but with USB Type C connector for charging. Actually I'm using it in my other device according to the exactly same thoughts.

You are probably right. However, the BLE transport was not removed from the 2.1 specification and supported by Microsoft Hello. And, anyways, for Arduino based DIY project existing…

You can not extract private key from ATECC508A while it can be an issue with custom key storage built on Arduino. The chip itself costs around one dollar so why not?

It is encrypted with MITM protection. That's why I do not believe in severe security issues in BLE. There can be problems with particular implementations, but in general it should …

From my experience - most people say "Arduino is ok" but struggle working with plain C. As well keep in mind number of ready-made libraries for Arduino that can be reused here almo…

I'm using a bluetooth keyboard and I type my passwords in plain text. I don't think that public key sent over bluetooth is less secure. So it's a very tricky topic and I think it's…

Thank you! :)

This project is a spin-off from my wireless biometric authenticator. I was asked to make it open source many times. Other than that - I've got one on my keyring as well. But buying…

Yes, I have seen this recently. Google is so unsatisfied with BLE in FIDO2 so they removed support for it from the Chrome browser.

Oh, right, need some documentation there as well. In general you can try the project with ESP32 development board and upload the firmware using `pio run -t upload -t monitor` Then …

Thank you! I'm looking for a simple and convenient solution as well.

There is small UART biometric module https://www.digikey.com/products/en?keywords=2304-100018754-... The biggest downside - it's more that 3 times more expensive than the device I …

I have a small hobby project - FIDO2 Authenticator built on ESP32 chip. For cryptography, I'm using ATECC508A co-processor. I want to use biometric authentication so I connected fi…
