Two-factor authentication coming to Google Accounts

posted 10 Feb 2011, 14:45 by Iain McLaren
Aimed at boosting the security of Google Apps accounts, two-factor authentication to the service is being rolled out imminently.

As well as requiring a username and a (typically weak or insecure) password, enabling the service will prompt for a numeric code before authentication will complete.

Unlike some costly 2-factor methods, a dedicated random number generator (keyfob) is not required. Instead, the code is delivered by SMS to the user's preferred mobile phone, or generated using a smartphone app. And there's no need to worry if you misplace that, as you can create backup codes for that eventuality.
