FEITIAN ePass K10 USB Security Key - Two Factor Authenticator - USB-A with FIDO U2F + FIDO2 - Micro-Size - Help Prevent Account Takeovers with Multi-Factor Authentication

What can I say? I works with everything I've tried it with: Duo, Google, LastPass, tons of websites, etc. It's FIDO2 certified. It tucks into the side of my computer, almost flush, so it doesn't get broken off. It is super convenient. I set it up with a PIN so I can leave it in my computer full time. I don't have to worry about someone attempting to use it when I'm not at my computer.

Great product

Sin problema en pc y se puede utilizar en celular con adaptador de usb-a a usb-c, cumple con su función al 100%, con el adaptador no requires que tenga NFC

Bought this as a cheaper alternative to dropping more money on a Yubikey. Ended up buying a Yubikey in the end as this only supports RSA, and I wanted a more secure key algorithm. Much happier with Ed25519 with Yubikey.If you want RSA, it's a great value, but I want a more secure option.

EDIT: I had one die after 2 years. For the price it's still worthwhile.The YubiKey Nano is a much better device; Much more flush, many more features, but the ePass K10 are less than half the price. Feitian products are poorly documented, but they work. If you're new to security keys, or if you're just very conscious of price, these are a good choice, if you don't mind a lack of information.I have these in laptops. When using them on a lap, it can be frustratingly easy to touch them by accident. By default mine had OTP enabled, which types a string of seemingly random numbers any time you touch them. If you go to Feitian's website and download the "ePassFIDO-NFC OTP Tool", you can change how the devices work. In my case I was in OTP+U2F mode. Switching to U2F mode solved my problem, making them only work once requested by software.
