Setting Up SSH Keys on macOS with Touch ID

macOS users can set up highly secure SSH authentication using the built-in Secure Enclave and Touch ID, which stores private keys in hardware that cannot be extracted or stolen. The setup requires just three commands: creating a secure identity, configuring SSH to use it, and retrieving the public key for services like GitHub. This approach offers superior security compared to traditional SSH key files since private material is never exposed and users receive a Touch ID prompt each time the identity is used for authentication.
