Two-factor auth now supported for improved account security

I just upgraded SJ to Xenforo 1.5, which supports Two-Factor Authentication for improved account security.

If you want to enable it for your account, hover over your username and in the bottom right of the popup box you'll see "Two-Step Verification".

It uses the same mechanism thats commonly used for Gmail, Dropbox, etc, so Google Authenticator and Authy both work fine.

There were a number of other feature improvements in the latest release, including thread-tagging, so if you have any questions or hit any bugs, let me know.
