My very first bad blog joke (back in October 2003) was tangentially related to knowledge-based authentication:
“When Patti Smith married Fred Smith, did she take her husband’s last name, or keep her maiden name?”
Because Patti didn’t change her name, but many people do.
Which means that even if a name is unique, it is not as accurate a form of identification as, say, irises.
If you don’t believe me, ask Richard Meyers and Thomas Joseph Miller.
Better known as Richard Hell and Tom Verlaine.
