The man who first invented the password to protect user accounts has died aged 93 of complications related to diabetes.
Computer pioneer Fernando Corbato oversaw a project which would allow different users to access a computer at the same time.
The technique, which he began during the sixties at Massachusetts Institute for Technology (MIT), paved the way for the development of today’s devices.
Using computers during th
e 50s was tedious because the huge, monolithic machines could only handle one processing job at a time.
So Corbato developed time-sharing, which divided up the processing power of a computer so it could serve more than one person at once.
The Compatible Time-Sharing System (CTSS) made it possible for multiple people to access a computer at one time and perform complicated mathematical programs.
Mr Corbato locked each account by putting a password on for each individual user which, like machines today, kept their files and programs hidden away from others.
Besides making computing more efficient, CTSS also inadvertently helped establish the very concept of digital privacy itself.
It introduced the idea of having people create individual accounts with personal passwords.
His system directly inspired operating systems like Linux and laid the foundation for many aspects of modern computing.
