Definition of password

The word "password" originates from the 14th-century Middle English phrase "parole of saport", which referred to a promise or oath of protection. Over time, the phrase was shortened to "password", and its meaning shifted to refer to a secret word or phrase used to gain access to a restricted area, a confidential message, or to verify identity. The concept of passwords has been around for centuries, with ancient civilizations using secret words, phrases, or rituals to grant access to sacred spaces or reveal hidden knowledge. The modern concept of passwords as we know it today, however, is a relatively recent development, dating back to the early 20th century with the invention of computer passwords. Despite its evolution, the fundamental idea of using a secret code to grant access or verify identity remains at the heart of the term "password".
