Compromised passwords are only part of what's wrong with Cybersecurity for the consumer

A solution that combines both data protection and authentication is what Internet of Things devices such as cameras, lights, and sensors need to fully secure their use.  Half measures such as digital certificates and user changeable passwords are only the equivalent of a band-aid stuck over a serious wound.

For really secure communications, you then need to share a new key each time you want to communicate information that is supposed to be secret. The use of a new key each time is considered to be equivalent to using what cryptographers call a one-time pad. A one-time pad harkens back to the days when an actual encryption key was distributed on paper and a unique sheet of paper was used each time. Because each key is used only once, cracking such encryption is difficult.
