Probably. At this point we are testings things out and want to move as fast as possible. We want to make Two-Factor Authentication completely transparent, and we'll be launching other exciting things to see how they work in the real world.

Once we have the experience nailed out, we'll ported to other platforms.

I hope you are planning a Linux release too. So many companies leave us out, even though we're even more willing to work past bugs and set things up correctly.

Presumably their is an HTML5 app available?
