Product reviews

FEITIAN Standard FIDO Security Keys
“Easy to setup and use. If you’re serious about security this is a good option with a fair price that makes it a good value.”
- L&M
FEITIAN iePass Lightning & USB-C Security Key
“Works great on my Apple Macs and iPhone. iPhone app let me add a security code to my key as well. Save yourself the money and get this over the Yubico YubiKey 5Ci. This one works perfectly and is half the cost of the Yubico brand. Very happy and highly recommend.”
- Brandon W.
FEITIAN USB-A, USB-C Security Keys
“As a long time user, I highly recommend this product for it's durability, usability, and compatibility. It achieves the same thing as a Yubikey (except for storing PGP keys, but if you don't know what those are, then it won't matter to you), for half the price. My current key has lasted me over 3 years, and I suspect it will last me far longer still.”
- Nathan G.
