Hi.
Yubikey has 2 slots. First slot is preinstalled with Yubikey OTP, second is empty.
I want to use HOTP+challenge response+PGP keys with one Yubikey. Is it possible?
1. Does PGP keys use any of 2 slots or it's separate from it?
2. Here http://www.yubico.com/wp-content/upload ... -Setup.pdf is written, that no more than 2 sites or services can be supported on a single YubiKey. That means i can use only one site/service with one slot? Or if i want to use multiple services and sites, i have to use static password, or u2f?
3. Is it possible to configure Yubikey on Windows machine and use it on Mac without Yubikey personalization tool later?

PGP, U2F and PIV are completely separate from the 2 slots.
Only the settings in the personalization tool require slots.

You don't need the personalization tool to use the yubikey.
