Yubikey-4 Concepts, Configuration and Use

Categories: Security

Logging in to internet sites (and private servers) with just a password is really not acceptable these days, at least for someone (like me) claiming to be interested in IT security. I therefore recently bought a Yubikey-4 authentication token.

Sadly, the documentation available from the manufacturer, and the internet in general, was not very helpful. I have therefore created some extensive notes on the Yubikey-4 which may be useful if you are also considering buying one (or have already done so).

On a similar topic, I have very brief notes on the pass commandline password-manager for Linux and totp commandline tools for Linux. All feedback is very welcome!
