Passkeys leverage public-key cryptography to enhance login security. Instead of passwords, they utilize a private key stored on the user's device and a corresponding public key registered with the online service. During login, the device uses its private key to sign a challenge issued by the service, proving possession of the correct key without ever transmitting it. This process, based on established cryptographic principles and protocols like WebAuthn, eliminates the vulnerability of transmitting passwords and mitigates phishing attacks, as the private key never leaves the user's device and is tied to a specific website. This model ensures only the legitimate device can authenticate with the service.
