Basically a mini-computer that generates an essentially unlimited stream of passwords, usually one per minute from a deterministic algorithm embedded in the device. The trick is that next password is predictable if you ...


This works similarly to any symmetric key one-time password (OTP) technology. Point 1 - This is not meant to replace your password but instead be a second factor of authentication. Without possession of the Yubikey you are unable to generate the code necessary to authenticate to a system. Point 2 - Well, it generates one time passwords so it is more ...
