Problem registering Yubikey


I have blue yubikey 2 which Im trying to link to my web vault.
I follow the instructions but when I save, it tells me I need a key?


Could you provide more info, like some screenshots per example ?
With blue yubikey I believe you need to use the “FIDO U2F” option, not the “Yubikey” one. Did you do that ?


I did answer my own question but forgot to press the reply button…Doh!!!
Thank you for for taking the time to reply, you are quite right it is the FIDO option for the blue key and everything is now working as it should.
