Post subject:  [QUESTION] - Yubikey sends wrong scan codes?

Hello guys,
I have recently bought a Yubikey and I'm having some problems with it. I'm living in Germany so I am using a keyboard with a QWERTZ layout. I want to use the second configuration to use a static password which will be used to unlock my computer. So I went into the configuration tool and typed in my password. To explain what the problem is I will use an example password. So I typed in: mg@3r I wrote the configuration but when I tested the output in a text editor the following password was written: mg"3r As you can see the @ was replaced with a ". I tested some other keys and found some other strange cases like this. For example if I input a " it will output a "ä". If I input a "ä" it will output nothing (for example wäfg --> wfg). So I can't use many special characters because the Yubikey seems to output a different scan code. Does anybody of you know what is happening here? Did I do something wrong? I hope you can help me :)

Greetings from Germany,

I've has a similar issue using a British keyboard with US software.

What I think you need to do is type your password into a text editor, such as Notepad or Word. You can see the correct characters. Then copy and paste it into the Yubikey configuration tool.

Hopefully that should work.

thanks for the answer. I tried it but unfortunately it does not work for me. As an example i added a picture to this Post which shows the Password I entered in the configuration tool. As said i can write it to the Yubikey but when I use the Yubikey i get this output: P"sswÄrd.

I solved it like this, use another password. I am on a Mac so I enabled US layout in addition to the Swedish one I normally use. Then I typed my password in a text editor. Now do the same thing with US layout. If there is a difference, then you will have problems like not being able to unlock filevault2 on a mac with your yubikey. And because you only can use US layout in the yubikey personalization tool you have to use a password that does not differ with layouts. It's really not yubico:s fault, it's just how things work in general. Well unless you're an american of course.

So when you have one that has the same characters for german and US layout you have a winner. (This does however lower the security quite a bit if you are not thoughtful of how you do this).

Good luck :-)

Thanks for your answer. So I checked the US layout and switched my german keyboard to an american layout. And well it works. I have a question now: Why isn't it possible to change the keyboard layout in the personalization tool? As you can see in the screenshot above there is a keyboard option but the only option I can select is a US keyboard.....
Does somebody have an idea how to fix this?

If someone has the will to build a table of his own, I guess we can integrate it in some way
