As a webmaster I know that it is important to keep a close eye on the security of web properties. This includes updating scripts to new versions when they came out, making sure files and directories have the correct access permissions, and that all users with access to the site have selected secure passwords.
Two-factor authentication has been added to various platforms recently. Google, Microsoft, Facebook, PayPal, Last Pass and more recently Dropbox have all implemented an optional two layered log in process on their sites and for their services.
Google Authenticator is a free plugin for the popular blogging platform WordPress that is adding two-factor authentication to a blog's login process. It uses Google's Authenticator app for that which is available for Android, iPhone and BlackBerry smartphones at the time of writing.
To enable two-factor authentication for a WordPress blog do the following:
When you now try to log in with the user account, you are asked to enter the username, password and the Google Authenticator code that you can generate on your smartphone.
A few notes:
The Google Authenticator plugin for WordPress is a great app for companies and webmasters who want to improve their site's login security. This renders brute force and dictionary attacks, as well as other forms of guessing or stealing account credentials useless. (via Caschy)
