Im just wondering if I ordered a Yubikey from Mt Gox how secure is it on Blockchain.info?
*side question: about how long does it take to get to you? Im in the states.

Mt Gox states you can only use their key for their website, but Blockchain has it listed as an option for their 2nd form factor.

Last but not least. Would I better off just ordering two? One from Mt Gox, and one from the main Yubikey website?

Thanks all!

If I remember correctly, the one from Mt. Gox only works with BlockChain.info for static password.  i.e., it is vulnerable to a replay attack.   The one from YubiKey is supported for true OTP against Blockchain.info's site.
