Abstract: Systems and methods that involve receiving an authentication request initiated by a relying party application on a computing device via Web Authentication (WebAuthn) interface; connecting to a nearby companion device; forwarding the authentication request to the authenticator on the companion device; receiving a response to that authentication request from the authenticator on the companion device; and transmitting the authentication response back to the sender application on the computing device for authentication purposes.

Abstract: Embodiments described herein provide systems and methods for secure and efficient user authentication across a variety of computing devices, such as desktops, laptops, smartphones, and tablets across operating systems such as Windows, MacOS, IOS, Android, and iPadOS. The system incorporates an authenticator application configured to communicate with internal or external user identifier scanners, such as RFID/NFC readers, fingerprint scanners, facial recognition cameras, and QR/Barcode scanners, using transport protocols like USB, BLE, or NFC. The authenticator application serves as a third-party passkey provider by interfacing with platform WebAuthn APIs, enabling WebAuthn-based authentication for native applications, browsers, and services, or alternatively as a browser extension, intercepting WebAuthn API calls directly within a browser environment.

Abstract: A system or method for hosting and managing FIDO authenticators in local network or cloud for users in a shared multi-user environment; which receives an authentication request initiated by a relying party application on a computing device via Web Authentication (WebAuthn) interface; and uses unique identifiers (such as RFID tags) to distinguish the hosted authenticators associated with each user to forward the authentication request; and receiving a response to that authentication request from the hosted authenticator on the local network or cloud; and transmitting the authentication response back to the sender application on the computing device for authentication purposes.
