The system was based on a simulated Hagelin rotor crypto machine, and first appeared in 6th Edition Unix in 1974.

'After typing PASSWORD, the system turns off the printing mechanism, if possible, so that the user may type in his password with privacy.' In the early 1970s, Robert Morris developed a system of storing login passwords in a hashed form as part of the Unix operating system. CTSS had a LOGIN command that requested a user password. The Compatible Time-Sharing System (CTSS), an operating system introduced at MIT in 1961, was the first computer system to implement password login. Passwords have been used with computers since the earliest days of computing. American paratroopers also famously used a device known as a 'cricket' on D-Day in place of a password system as a temporarily unique method of identification one metallic click given by the device in lieu of a password was to be met by two clicks in reply. The challenge and response were changed every three days. 101st Airborne Division used a password- flash-which was presented as a challenge, and answered with the correct response- thunder. Passwords in military use evolved to include not just a password, but a password and a counterpassword for example in the opening days of the Battle of Normandy, paratroopers of the U.S. If any one of them is missing, he makes inquiry at once, as he knows by the marks from what quarter the tablet has not returned, and whoever is responsible for the stoppage meets with the punishment he merits. So that if all those issued are returned, the tribune knows that the watchword has been given to all the maniples, and has passed through all on its way back to him. These latter are obliged to deliver the tablet to the tribunes before dark. All do the same until it reaches the first maniples, those encamped near the tents of the tribunes. The way in which they secure the passing round of the watchword for the night is as follows: from the tenth maniple of each class of infantry and cavalry, the maniple which is encamped at the lower end of the street, a man is chosen who is relieved from guard duty, and he attends every day at sunset at the tent of the tribune, and receiving from him the watchword-that is a wooden tablet with the word inscribed on it вЂ“ takes his leave, and on returning to his quarters passes on the watchword and tablet before witnesses to the commander of the next maniple, who in turn passes it to the one next to him. Polybius describes the system for the distribution of watchwords in the Roman military as follows: Sentries would challenge those wishing to enter an area to supply a password or watchword, and would only allow a person or group to pass if they knew the password. Passwords have been used since ancient times. 7 Alternatives to passwords for authentication.4.4.3 Hash-based challengeвЂ“response methods.4.4.2 Transmission through encrypted channels.4.4.1 Simple transmission of the password.4.4 Methods of verifying a password over a network.4.2 Limits on the number of password guesses.4.1 Rate at which an attacker can try guessed passwords.4 Factors in the security of a password system.2 Choosing a secure and memorable password.A passphrase is similar to a password in usage, but the former is generally longer for added security. A memorized secret consisting of a sequence of words or other text separated by spaces is sometimes called a passphrase. If the permissible characters are constrained to be numeric, the corresponding secret is sometimes called a personal identification number (PIN).Дespite its name, a password does not need to be an actual word indeed, a non-word (in the dictionary sense) may be harder to guess, which is a desirable property of passwords. In general, a password is an arbitrary string of characters including letters, digits, or other symbols. When the claimant successfully demonstrates knowledge of the password to the verifier through an established authentication protocol, the verifier is able to infer the claimant's identity. Using the terminology of the NIST Digital Identity Guidelines, the secret is held by a party called the claimant while the party verifying the identity of the claimant is called the verifier. Traditionally, passwords were expected to be memorized, but the large number of password-protected services that a typical individual accesses can make memorization of unique passwords for each service impractical. A password, sometimes called a passcode (for example in Apple devices), is secret data, typically a string of characters, usually used to confirm a user's identity.
