Yubico Forum

Hello

I have bought two Yubikey's and so far I am quite impressed with this solution. I am using one key as an single-factor OTP generator with the second configuration holding a static password. Now I would like to configure my second yubikey holding the same static password... is this possible? Somehow I got lost within the configuration tool... have I missed some configuration thing within the tool?

Regards

okay i just stumbled over this thread

viewtopic.php?f=6&t=513&p=2229&hilit=backup#p2229



Now my question is: how can i find out my current {public, private}-id and aes key? So I can reprogram my second yubikey.

I would like to archive the following about which I am still not sure if its possible:

Yubikey A:
Configuration 1: otp_single_factor_mode_with_identity_of_yubikey_a
Configuration 2: static_32_char_pass

Yubikey B:
Configuration 1: otp_single_factor_mode_with_identity_of_yubikey_b
Configuration 2: same_static_32_char_pass_as_yubikey_a

Regards

It is not possible to get the current public-id, private-id and aes key values for your Yubikey unless you have recorded them while reprogramming the yubikey in static password mode.

You have to program your Yubikey again. While programming your Yubikey please record public-id, private-id and aes key values and use the exact same recorded values for reprogramming the other Yubikey in order to configure it to emit the same static password.

Thanks for your reply. So this as a result means that i can't change my static password without reprogramming the whole yubikey?

Yes, for emitting the same static password you need to reprogram both the YubiKeys.

Cheers, thanks for the post. I'm going to reprogram my keys right now. With a 63 character password I feel it's a really good Idea to have a second Yubikey hanging around in case of an emergency!
