The concept of passwords has deep historical roots, tracing back to ancient times. Two anecdotal tales from the Bible illustrate the early use of verbal passwords as a means of security and identification.

The Shibboleth Incident

In the Book of Judges (12:6), during a conflict between the Gileadites and the Ephraimites, the Gileadites assigned a simple, yet effective, security measure to distinguish friend from foe. They asked each passerby to pronounce the word “Shibboleth.”

Due to dialectical differences, the Ephraimites pronounced differently, as “Sibboleth.” This linguistic password served as a tool to identify individuals and decide their fate, safe pass or execution.

Rahab’s Secret Agreement

Another biblical tale is mentioned in the Book of Joshua (Chapter 2), Rahab, a woman from Jericho, provided shelter to two Israelite spies. Aware of the danger, Rahab made a pact with the spies: in exchange for her protection and help in escaping the city, she requested her family’s safety during the Israelite invasion.

The spies agreed and gave Rahab a physical ‘password’ for protection: they instructed her to tie a scarlet cord in her window. This cord was a signal to the Israelite forces to spare everyone in her house, acting as a secret symbol amidst the chaos of battle.

From Ancient Codes to Modern Security: The Timeless Use of Passwords

These tales reflect the ingenuity and resourcefulness of individuals in using various forms of ‘passwords’ to communicate, protect, and uphold agreements. From verbal codes and auditory signals in ancient times to today’s complex alphanumeric and biometric passwords, yet the fundamental concept remains the same: to protect, authenticate, and control access.
