Broken Link - 404

Hello there!

I am writing to report a broken that I found on the following page:

https://admin.fedoraproject.org/accounts/yubikey/?_csrf_token=6b1241566bf2bf361126a92540bb662f4f53e461

There is written:

"For more information, see the user guide: http://www.yubico.com/files/YubiKey_manual-2.0.pdf"

That link is broken. Since it is always best to avoid broken links, I think it will be necessary to find a new link to that content.

Good luck!

WIth my best regards,

Rodrigo de Araujo
