Review: FEITIAN ePass K9: A Rugged, Reliable Security Key You Can Count On - I’ve been using the FEITIAN ePass K9 for the past couple of months, and it has completely transformed how I secure my online accounts. From the moment I unboxed it, I could tell this key was built to last—its solid casing feels rugged yet refined, and the NFC antenna is seamlessly integrated so there’s no wobble or loose parts. It slips onto my keychain without weighing me down, and even after dozens of pockets and backpacks, it shows zero signs of wear. Setting it up was a breeze. I plugged the USB-A connector into my laptop, tapped the device when prompted, and in under two minutes I had both FIDO U2F and FIDO2 protection enabled on all my critical accounts—Google, GitHub, and even my banking portal. The NFC feature works flawlessly with my phone, too: a quick tap against the back of my device, and I’m authenticated instantly, no fiddling with cables or adapters. I especially appreciate how it remembers multiple account registrations; whether I’m logging into my personal email or my work VPN, the ePass K9 always pops up correctly. Reliability has been rock-solid. In all my logins—even after system updates, browser changes, and cross-platform use—the key never fails to authenticate on the first try. No batteries, no software to update, just “tap-and-go” security that I never have to think about. If you’re serious about safeguarding your digital life, the FEITIAN ePass K9 is hands down the most durable, functional, and reliable security key I’ve ever tested. It’s worth every penny for that peace of mind.
Review: NFC doesn't work on the 4 units purchased - Long time Yubico user who gave this Titan brand a shot because of the sale price and buying for my team. These keys are comparable in almost every way in function and look except for one important feature. I specifically bought this because of the FIDO advanced support and the NFC as most of my users use iPhones or are often mobile. Recently months after purchasing, we have discovered the NFC function hasn't worked out of box. The NFC was the main reason for these keys which 4 of 4, non sequential serial numbered, pocket kept (or better), do not work. After testing all the keys and against my NFC Yubico and found no issues with the devices or the Yubico, we will be reaching out for support. Will update should resolution having been made.
