This security authentication is provided by
many online services, Two-factor authentication is an additional
security service. In this authentication an extra security test include code
from an SMS message, as well as a password. Nowadays it is very difficult for
the user to remember lots of online passwords, and it can involve the variety
among falling victim to cyber criminals and staying safe. This security service
is added on many sites like Twitter, Google, LinkedIn and Dropbox and
more. This security check is accepted by almost online service sites but
Twitter and LinkedIn accepted this security service after a high-profile hacking.
Authentication in this security check may vary but normally
it occupies either an automated SMS or an app which generates codes
and after entering the provided password site will be asks for the password or
in some sites an app is used to enter the code.
This security system is very safe than password protection
that can able to keep away user from hacking and other types of online scams. But
keep in mind that that it is not a ‘magic stick’ and hackers are trying to
break this security system.
According to ESET Senior Research Fellow David
Harley, “The sad fact is, static passwords are a superficially cheap but
conceptually unsatisfactory solution to a very difficult problem, especially if
they aren’t protected by supplementary techniques. One-time passwords and
tokens are much more secure, especially when implemented in hardware as a
two-factor authentication measure.”
