New approach combines ECDSA with post-quantum algorithm called Dilithium.

The PQC algorithm used in the implementation of FIDO2 security keys takes a more cautious approach. It combines the elliptic curve digital signature algorithm—believed to be unbreakable by classical computing but easily broken with quantum computing—with a PQC algorithm known as Crystals-Dilithium. Crystals-Dilithium is now one of three PQC algorithms selected by NIST for use with digital signatures.
