In general, fingerprints should not be treated as a password or key. They unfortunately are being used as such by Apple and Samsung and these fingerprint locks. A key is something you keep private, but you leave your fingerprint on everything, including the doorknob you&#x27;re trying to keep locked. Additionally, once compromised, the key cannot be revoked. I don&#x27;t doubt it is much more convenient, but I would personally never trust the security of my home to one. The one area that electronic locks clearly win out on is with auditability. You can show when the door was opened and by whom, if they each have separate keys. And when a key is lost, that specific key can be revoked, rather than changing the entire lock.
