Supported Sites by Thetis Fido

Hello everyone,

As the title suggests, I am trying to find which sites the Thetis Fido U2F security key supports. Does it support all the sites with U2F or just some of them? Thanks!

EDIT:

Actually, I would prefer purchasing a yubikey as it supports lastpass too, but the problem is that my phone does not support NFC and if I purchase the type c one, then I will not be able to use it on my computer (or I can just purchase an adapter but it'll be hard to carry it along with my keys without losing it).
