Two factor authentication increases security
Two factor authentication in addition to complex passwords are very difficult to guess or even crack using commonly available code breaking software. Password complexity is often built on the length of the word and the difficulty one has in guessing it. The more complex a password you create, the more secure you are making your data.
Passwords that feature uppercase and lowercase letters, numbers, and characters are much more challenging for a hacker to crack. Integrating numbers and characters into phrases also helps guard against dictionary attacks. However that often is not enough.
With two-factor authentication, a user logging in to a service or device supplies a second piece of information in addition to a password, thus making it impossible for another party to gain illicit access to the user’s accounts without all the separate pieces of information.
Following similar initiatives by Apple, Google and Facebook, Microsoft is enabling two-factor authentication for its Microsoft Account service, the log-on service for many of its online and desktop products.
Microsoft is implementing additional verification methods such as a short code sent to the user’s mobile phone, which is then entered in addition to the password, or by asking the user to supply additional information, such as an alternative email address.
