Final answer:
Stronger authentication is provided by multiple factors, strong passwords, and keyless entry locks. Multiple factors, such as a combination of something you know, something you have, or something you are, enhance the security of authentication.
Step-by-step explanation:
Stronger authentication is provided by multiple factors, strong passwords, and keyless entry locks. Multiple factors, such as a combination of something you know (e.g. password), something you have (e.g. a smartphone), or something you are (e.g. fingerprint), enhance the security of authentication. Strong passwords, which are long, complex, and unique, are harder to crack and provide additional protection. Keyless entry locks, like biometric locks based on handprint geometry, offer stronger physical security for access control.
