Obviously,
computers can't be locked in the physical sense to impede unlawful access. The
standard security measure computers use to deter unauthorized access is the
password prompt, which serves as an electronic lock of sorts. The origins of
the password could be traced as far back as the era of the Roman Empire, when
the Empire's watchmen would discreetly pass around a “watchword” that only they
would know of.
Passwords
are still some of the most reliable applications designed for security; hackers
can try to crack the code, but it will take them a considerable amount of time
to do so. To further bolster security, it's even possible to create rotating
passwords that would make access to the system next to impossible for
criminals. For all its strengths against decryption, however, passwords can
complicate the lives of those using them.
Those who
use long and complex passwords might have difficulty remembering such codes.
Thankfully, there are password managers that can help users key in their
passwords without challenging their memory. They could either come in the form
of software (either as an application or a cloud-based service) that safely
store a list of passwords for users, or as a portable physical device (such as
a USB drive) that keeps the passwords inside them.
