FIDO Authentication, developed by the FIDO Alliance, is a global authentication standard based on public key cryptography. (https://fidoalliance.org/what-is-fido/)
The FIDO ("Fast IDentity Online") Alliance is an open industry association launched in February 2013 whose stated mission is to develop and promote authentication standards that "help reduce the world’s over-reliance on passwords".[1] FIDO addresses the lack of interoperability among devices that use strong authentication and reduces the problems users face creating and remembering multiple usernames and passwords.

FIDO2 passwordless authentication relies on cryptographic algorithms to generate a pair of private and public passkeys—long, random numbers that are mathematically related. The key pair is used to perform user authentication directly on an end user’s device, whether a desktop computer, laptop, mobile phone, or security key. A passkey can be bound to a single user device or aut
