    I think the wifi version of this recently came out which is much more useful in our Orwellian IOT world

      We're planning on selling them as well but they're currently on backorder.

    Here's a fun RP2040 project for you: Pico Keys to use RP2040 board as a FIDO2 key (like a YubiKey) on websites.

    (though RP2040 boards with built-in USB connector may be more useful for this purpose)

      Which hardware is recommended?
      For boards using either the RP2350 or ESP32-S3 chips, both are recommended. The RP2350 stands out with a larger One-Time Programming (OTP) region, providing additional space for storing secure keys and configurations, and is likely to offer greater support for future updates. However, the RP2040 is not advisable for applications requiring hardware security, as it lacks built-in security features essential for robust protection.

        Absolutely. Though it's gonna take a while to see RP2350-based boards that suitable for this purpose.

        As a cheap, hobbyist alternative to overpriced FIDO2 keys (yeah I'm talking to you Yubico!), even unprotected RP2040 Pico Fido firmware is already safer than password + OTPs given you safeguard the hardware itself.
