Review on 🔑 FEITIAN OpenSK V2 USB Security Key - Open-Source Two-Factor Authenticator - USB-A - FIDO2 + FIDO U2F Support - Enhance Account Security with Multi-Factor Authentication by Brendan Baker

UPDATE: I couldn't get this security key to work on Coinbase.com so I gave it a bad rating. But I was wrong. I don't know why but I tried again and now it works PERFECTLY. So I went from 1 star to 5 stars. If you're having trouble, keep trying. Very cheap price and works great so far. ### (previous review) FEITIAN security keys are mentioned in the New York Times. SO I am very disappointed that the OpenSK key sent to me turned out to be dead on arrival. I've tried it on three different computers and "nothing". I think it's an old obsolete model which is why it's so cheap. Note that there is NO documentation on how to use it, so you'll have to search the web. If you can get one that works. it should be great.
