What did the father of the computer password come to think of it?

Fernando Corbató led the team behind MIT’s time-sharing system, first demonstrated in 1961 and widely credited as the first computer system to use passwords. “Putting a password on for each individual user as a lock seemed like a very straightforward solution,” he told Wired in 2012. More than fifty years after that first demonstration, he told the Wall Street Journal that passwords had “become kind of a nightmare with the World Wide Web.”

Over the years he had collected about 150 passwords of his own, on three typed pages. He confessed to keeping a crib sheet, which he called “a mild no-no.”
