I’m trying to set Yubico.

I’ve got the Yubikey security info;  
because it is explained in the guide.

The “Add private key” section,  
is not indicated.

What values do we input in:  
Type  
Slot  
Key

and what are the 3 checkboxes below?

Follow: [Yubicloud (Not Officially Supported)](https://docs.crp.to/usersguide.html#yubicloud-not-officially-support)

I didn’t see any “type” in there. As for slots in the Yubikey personalization tools, that’s for YubiKey.

What you need to write into OnlyKey are just 3 pieces of strings: `Public Identity`, `Private Identity` and `Secret Key`. And what you need additionally to let YubiCloud work is the serial number of a YubiKey, you will need it when uploading credentials to [YubiCloud](https://upload.yubico.com/).

Thanks.  
The “type” thing, is because it was confusing to see in the Advanced TAB,  
the “Add private key”, which I suppose is for another function.
