How about 2-factor authentication, as discussed in the article?
- kristofferR 15y agoSMS is not global and is quite expensive to get started with. Only the major players like Google can roll out worldwide SMS authentication. Email is out of the question because it often takes several minutes to receive an email (due to POP-fetching intervals etc)

Here's the open source project for the mobile app and PAM module: http://code.google.com/p/google-authenticator/ http://code.google.com/p/google-authenticator/ (Disclaimer: I worked on this.)
