Can WiKID work across multiple enterprises without federation?

Posted by: root 15 years, 3 months ago

Yes. Unlike most two-factor authentication systems, WiKID uses public key crypotgraphy instead of shared secrets. This means that a single WiKID token can support an unlimited number of relationships with WiKID servers without a reduction in security.

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.

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.

What do I do when my wireless device is out of network coverage and I want to login with my WiKID credentials?

The WiKID System falls back to a challenge-response mechanism, which is part of the Radius standard. After the user enters their PIN, if the device is out of wireless network coverage, the WiKID Two-factor Client will prompt the user for a Challenge.

If the user is logging in to a VPN service, for example, the user enters their username, but leaves the passcode box empty. The VPN service responds with the Challenge, which the user enters into the WiKID client.

The challenge is encrypted with the user’s PIN and an offline-challenge secret and presented to the user Base-62 encoded (to keep the length manageable). The user enters this response for a passcode. The VPN service sends the Username, the Challenge and the Response to the WiKID server. If the WiKID Server can decrypt the Response can get the Challenge, the user is granted access.

How does WiKID enable Active Directory password resets?

Posted by: root 15 years, 3 months ago

A password-reset domain is configured on the server with Administrator rights to reset users' passwords. When a user forgets their password, they choose the password reset domain on the WiKID client and enter their PIN. If PIN is correct, the encryption valid and the WiKID account is active, the WiKID server resets the Active Directory password to the one-time passcode and forces the user to change their password at the next login.
