Passkeys are particularly secure because they are designed with no shared secrets and are resistant to phishing. This approach means that when using passkeys, sensitive information isn't stored in a manner that can be intercepted or stolen. Instead, a unique cryptographic key pair is generated, where one key remains on the device and the other is safely stored by the authentication system. This process ensures that the actual authentication never involves the transmission of easily exploitable secrets, like traditional passwords.

Additionally, the resistance to phishing attacks stems from the fact that a passkey cannot simply be captured by malicious sites. Since users are not entering a password that can be stolen, the risks associated with phishing attacks are significantly minimized. In contrast, the other options such as the ability to share passwords or having them work only on certain devices do not necessarily contribute to the security of passkeys and may even compromise it by introducing vulnerabilities. Lengthy passwords, while they can improve security, do not inherently provide the same level of protection against modern authentication threats as the principles behind passkeys.
