For decades, passwords have been the common backbone (headache) of authentication and are well known to lack in security while being frustrating and difficult to use. As we continue to see daily data breaches, the reality of moving away from weak static credentials and killing the password is upon us. Join this session to learn how FIDO2 and WebAuthn open authentication standards, in conjunction with YubiKeys, are solving the elimination of passwords at scale. Hear how organizations like Microsoft have implemented these standards for a true passwordless experience and find out how your organization can follow suit. You'll gain a greater understanding of how to achieve a modern and flexible security architecture through the use of FIDO open standards and hardware authenticators.
