About the Team
FIDO stands for Fast Identity Online. It is the state-of-the-art authentication that is arguably the most secure of all currently available authentication methods. Our team's mission is to protect both internal and external users across all company applications with secure and user-friendly FIDO2 authentication. We have a variety of tech stacks, including WebAuthN server, mobile and web SDK, tools, and other components that implement FIDO2 and support its use.
There are two major initiatives in our team, mainly separated by the different types of customers we serve:
- Internal ToE(nterprise): Empower every employee as a phishing-resistant user.
- External ToC(onsumer) and ToB(usiness): Deliver a seamless and secure FIDO2 authentication experience across all company products.
