The first Thursday in May is World Password Day. Here are ten facts about passwords.
The first passwords were spoken words, used, often by the military, to distinguish between friends and enemies. People you wanted to allow into your base would know the word to say. Enemies would not. In the Roman Empire, soldiers were given “watchwords” to be spoken to the night watchmen.
In the 11th century BCE by soldiers of Gilead used the password “shibboleth”. They didn’t care so much if their enemies found out what it was, because they would give themselves away by pronouncing it differently.
The first computer passwords were used by American computer scientist Fernando Corbató in 1961 to control access to the Compatible Time-Sharing System (CTSS), a general-purpose operating system.
Passwords that consist only of numbers may be called passcodes or personal identification numbers (PIN).
59% of people use the same password for several platforms. 20% of employees share passwords with colleagues. A person usually changes the password every 2.5 to 3 years on average.
The most commonly used passwords include 123456, password, qwerty123 and iloveyou.
Research has shown that women are more likely to use personal names in their passwords, while men use words relating to their hobbies. People are 3 times more likely to use their pet’s name rather than that of a family member. Most of the sources I looked at for this one went on and on about how bad this is. That said, a famous hacker who was on the FBI most wanted list used his cat’s name as his password, followed by ‘123.’
The launch code for US nuclear missiles was ‘00000000’ for 20 years.
At one time those in the know could access any profile on Facebook by entering the password ‘Chuck Norris’ and on Hotmail using the password ‘eh.’
An eight-character password containing a combination of upper and lower-case characters has a total of 53 trillion billion combinations.
