By chance I picked up a Mt Gox yubikey quite cheaply, and thought I might try and reprogram it with a static password in slot one and an OTP in slot two.

However, when I try to do this using the Yubico customization tool, it says that it is 'protected'.

1. Is it actually possible to reprogram a Gox Yubikey, or have they locked them down with a password?

2. If I do manage to reprogram it, will I be able to move the OTP into slot to and still authenticate using Yubico servers?

3. If not, is it possible to set up my own server to authenticate with services like Gmail?

Cheers
