If you are planning to adding the Yubikeys as a hard token for your users in ESET Secure Authentication installation you'll most likely have ended up at the ESET guide on how to do it found here:
https://techcenter.eset.nl/nl/kb/articles/using-yubikeys-with-eset-secure-authentication

The problem with this guide is, it assumes you only use the Yubikey as a hard token for ESET and NOTHING else.
Like most people, I use these keys as 2FA for facebook for example.

I run a pair of Unifi AC Pro AP's at home and with the Unifi Controller installed on Debian in a VM. We all know the drill, once in a while a update comes along and it's time to update.
Well for me... the normal instructions given by Unifi doesn't work for me, so I had to find another way to install the update...
