FIDO2 Authentication

What is FIDO2 Authentication?

FIDO2 is an open standard from the FIDO Alliance that enables passwordless login via public- key cryptography. It relies on WebAuthn (browser-side API) and CTAP (smartcard/device protocol) for secure authentication. With TrustSEC’s Java Card applet, keys never leave the card —ensuring decentralized and phishing-resistant credentials trustsec.net .
