Quite handsome and useful looking. Good job!

Just a quick question, under security it says:

>>". Authy Bluetooth will only talk to pre-approved computers and all messages are encrypted."

Just wondering if you can speak to what sort of encryption and safeguards you've got going on here. The docs cover how the tokens are created, but not the communication between phone and mac.

Seems like an awesome thing but I wouldn't feel comfortable using it for work without knowing a bit more.
