Abstract: An authentication system with an automatic authentication mechanism and an automatic authentication method are provided. The authentication system includes a server device and a gateway device. The gateway device is coupled to the server device. The gateway device is configured to act as a fast identity online (FIDO) client to send a gateway device registration data to register the gateway device in the server device acting as a FIDO server, and then the gateway device defines itself as initialized and connected. The gateway device periodically sends data to server device for authentication to maintain a trusted connection between the server device and the gateway device.

Abstract: A security key device, a security authentication system, and a security authentication method are provided. The security key device includes a communication module, a security processing unit, and a processing unit. The security processing unit executes an authentication module, a bridge module, and a management module. The authentication module is configured to operate according to a Fast IDentity Online protocol. The management module is configured to operate according to a Public Key Infrastructure protocol. The authentication module receives through the communication module an input command provided based on the Fast IDentity Online protocol by a web authentication module of a browser executed by an electronic device. According to a header of the input command, the authentication module determines that the input command is used to be executed by the authentication module or used to access the management module through the bridge module.

Abstract: An operating system with automatic login mechanism and an automatic login method are provided. The operating system includes a first electronic device, a second electronic device and a server device. The second electronic device includes a biometric sensor. When a login event of the first electronic is triggered, the first electronic device sends a login request to the second electronic device directly or via the server device, so that the second electronic device performs a biometric verification by the biometric sensor according to the login request. When the biometric verification is passed, the second electronic device sends a first login credential to the first electronic device directly or via the server device, so that the first electronic device performs an automatic login operation of the first electronic device according to the first login credential.

Abstract: A login mechanism for an operating system, including: a computer device, loaded with a computer operating system; and a mobile device, capable of sending a login password for the computer operating system, and capable of authenticating a human biometric feature. In the login mechanism of the present invention, the login password for the computer operating system is stored on the mobile device. When a user logs in to the computer operating system, the mobile device authenticates a biometric feature. After authentication succeeds, the mobile device transfers the login password to the computer device, so as to log in to the computer operating system. A user does not need to enter a login password, and two-factor authentication including login password authentication and biometric feature authentication is used to protect the security of login to the computer operating system.
