FIDO2

FIDO2 is a passwordless authentication protocol developed by the FIDO Alliance that enhances security by using biometrics or PINs instead of passwords. It prevents phishing attacks and improves user experience. Supported by platforms like Keycloak, FIDO2 enables strong authentication with cryptographic keys. It offers two key types: device-bound keys for workforce authentication and multi-device keys for consumer authentication. While FIDO2 eliminates password vulnerabilities and streamlines authentication, its implementation can be complex due to platform, browser, and device compatibility requirements.
