Microsoft Hops On Two-Factor Authentication Bandwagon
itwbennett writes "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. Users will find instructions on how to add a second form of authentication on the Microsoft Account settings page. The chief form of secondary authentication will be a short code sent to the user's mobile phone, the number of which Microsoft will keep on file, each time the user logs on."
It is 2 factor authentication.
The 3 authentication factors are:
Something you Know.
Something you Have.
Something you Are.
This meets 2 of those factors, a password (know), and your phone (have).
