The new YubiKey 2.0 provides an interesting feature called "Strong password policy" where we can program the YubiKey to generate very long static passwords with upper, lower case letters, numbers and an "!" special character. We need to use the new Yubico configuration utility to utilize this feature. The new Yubico configuration utility and the user manual can be downloaded from the following link:
http://www.yubico.com/developers/personalization/For using this feature follow the steps given below:
1) Select the "Create a static YubiKey configuration (password mode)" from the Select task screen
2) Choose either "Basic" or "Advanced" mode and select the appropriate number of characters
3) Provide the appropriate values
4) From the "Specify output parameters" screen, select the options provided under the "Strong password policy" and program your YubiKey
Selecting all the options of the "Strong password policy" will result in the generation of a similar static password as given below:

Please also note that the static password emitted from the YubiKey when configured in "Basic" or "Advanced" static YubiKey configuration mode cannot be set by the user. The Static password is generated as a result of an encryption function involving the AES key and YubiKey parameters.
However, You can use the "Scan code mode" feature available under the static YubiKey configuration of the YubiKey configuration utility to program the YubiKey 2.0 to emit your own password of up to 16 characters.
We hope this helps!
