Passkeys live in software; security keys live in hardware. See how they compare on phishing protection, syncing, and recovery — and when to use each, or both.
Learn how Arduino developers can prototype secure signing workflows with a Cryptnox hardware wallet smartcard while keeping private keys out of microcontroller firmware, serial logs, and exposed embedded memory.
Cryptnox has published new Arduino and C++ SDKs to help developers build prototypes, integrations, and applications around smartcard-based hardware wallets, secure signing workflows, and NFC smartcard development.
