AlterEgo 2-Factor Authentication

File this under the "Why didn't I think of that" category. MailChimp just released a super cool new product called AlterEgo that enables 2-factor authentication for web apps using an IPhone application.

If you've done anything with production systems, then you've probably used 2-factor auth and have always found it to be a pain, especially if you've had to add it to some software you're building. This product looks to bring a simplified version of 2-factor auth to webapps that can provide a really nice additional layer of security to webapps that need it. I'd love to hear from anyone who has used this product, either as a user or as an integration.
