A technician has been tasked with using the fastest and most secure method of logging in to laptops. Which of the following log-in options meets these requirements?

A PIN is faster than a complex password but is generally less secure than a fingerprint, as it can potentially be shoulder-surfed or brute-forced if not combined with other security measures.

A username and password can be secure if complex but is typically slower to enter than a biometric method like a fingerprint and is susceptible to various attacks like brute-force or phishing.

SSO (Single Sign-On) provides convenience for accessing multiple systems after an initial login but is a management mechanism, not a primary login method to the laptop itself in terms of speed and direct physical security.
