AuthenticatorChooser Aldaviva

AuthenticatorChooser is a background program designed to automate the selection of USB security keys in Windows FIDO/WebAuthn prompts. It eliminates the need for manual interaction by skipping Bluetooth phone pairing options and automatically choosing the USB security key when available.

Key Features:

• Automatic Selection: AuthenticatorChooser automatically selects the USB security key option in Windows FIDO credential provider prompts, streamlining the authentication process.
• Bluetooth Bypass: The program skips the Bluetooth phone pairing step, ensuring that users who prefer USB security keys are not forced to interact with unnecessary steps.
• Shift Suppression: Users can temporarily prevent the program from automatically selecting the USB key by holding the Shift key when the prompt appears, allowing for manual selection if desired.
• Customizable Behavior: Advanced users can customize the program’s behavior using command-line arguments, such as forcing it to always skip non-security-key options.

Audience & Benefit: Ideal for users who prioritize physical security keys over Bluetooth-based authentication methods. AuthenticatorChooser provides a seamless and efficient experience by reducing manual steps and eliminating delays caused by additional prompts. It is particularly beneficial for those who frequently use USB security keys and seek to minimize friction in their authentication workflows while maintaining robust security practices.
