simple and it works

at first i wasnt’ sure who i can trust. i mean this plugin is written by a stranger, not yubikey. So i got my unique api key from yubikey.co and installed it. Entered it into the plugin. enabled the user from user/profile, plugged in my key to generate a key, saved, logged out and logged back in and it worked. I tried any NON enabled user and of course did not enter a key via my key and got in. So here’s my test that this plugin author is actually communicating with yubikey.co, I changed just one letter in my api id and tried logging in, and i could NOT. Soo… this tells me that it’s trying to communicate with yubi apparently to authenticate, otherwise it would not know. Alternately, i could have deleted my api key from yubikey.co to test. regardless, it works seamlessly. I’m using WP 5.8.6
