Can I use WiKID for two-factor authentication for GDM/XDM/Gnome/KDE login?
Posted by: root 15 years, 3 months ago
Most Linux services use PAM, so 'Yes'. Just configure /etc/pam.d/login to use Radius and you should be good to go.
Will WiKID Strong Authentication work in my network?

The short answer is 'yes'. Chances are that your network devices, whether they are Cisco switches or Nortel VPN concentrators, a custom web-application or a home-baked Linux firewalls, WiKID will work out of the box. Additionally, we can add network protocols with relative ease, if you're not covered by Radius, LDAP or the other major protocols. Finally, we offer a simple API and implementations in a number of languages - Java, COM, Python, PHP and Ruby - so you can easily add two-factor authentication to your custom applications.
But we can't ask non-employees to run software on their PCs. What can we do about vendors?

We suggest you use USB tokens or wireless tokens.
How can a software token be as secure as a hardware token?
Posted by: root 15 years, 3 months ago
Simple, really.
There are two factors: possession of the private key and knowledge
of the PIN. The private key is stored on the client. Our PC client, for
example, this key is in a password-protected PKS12 encrypted file. If
someone steals this file and brute-force attacks it and gets the
passcode, they are only half-way there.
They still need the PIN. The PIN is stored encrypted on the WiKID
server. Losing the private key is the equivalent of losing a hardware
token. You're only half-way there.
Typical software tokens store the PIN, the secret and the algorythm all in the client. Clearly this is not the way to do it.
Can more than one passcode be valid at one time?
Posted by: root 15 years, 3 months ago
No. Only one passcode can be valid at one time. Most time-synchronous token solutions allow more than one passcode to be valid at one time so that the login window is long enough or to account for clock drift. With only a 6 digit passcode, this can reduce security.
