Use it for any site that allows them. I have two, may even get an extra as backup.Good quality, better security to email or phone. Works for PC, really easy to setup. The NFC version doesn’t work on iOS though. ### ⭐⭐⭐ Ok and does what it says but ...... *by on Reviewed in the United Kingdom 9 August 2023* It is a goof device but it is complicated and confusing to set up and I'm technically minded being an engineer. I would recommend as a security device but be mindful of the sometimes painful setup process and this does not work with alot of sites I found the easiest way is to use to secure Google and thenuse Google to sign into the sites your then only setting up the key in one place. ### ⭐⭐⭐⭐⭐ From a First Time user's POV I Give this 4.5 Stars *by on Reviewed in the United Kingdom 16 February 2024* I Had Never Used a Fido2 Fido U2F Key Before and was unsure how easy or hard it would be to set-up & Use, But After 10 Mins Reading the Supplied mini Instruction Guide i had Secured my first Account Using It.The Only Thing Worth Mensioning is you can not secure every Account you Own - Only Selected Ones Like Google , Microsoft EtcSo I would Give it 5 Stars for Value, 5 Stars for ease of Use & 4 Stars for Durability as its Only Half Metal the Other Half is Plastic ## Frequently Bought Together - Thetis Security Key - U2F and FIDO2, USB A, Two Factor Authenticator with Bluetooth, Multi-Layered Authentication Protection HOTP U2F Compatible Windows, MacOS, Gmail, Linux - Black - Thetis Pro FIDO2 Security Key, Two Factor Authentication NFC Security Key FIDO 2.0, Dual USB A Ports & Type C for Multi layered Protection (HOTP) in Windows/MacOS/Linux, Gmail, Facebook,Dropbox,Github - Yubico - YubiKey 5 NFC - Two-Factor authentication (2FA) Security Key, Connect via USB-A or NFC, FIDO Certified - Protect Your Online Accounts --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/477192228-thetis-security-key-u2f-and-fido2-usb-a-two-factor](https://www.desertcart.no/products/477192228-thetis-security-key-u2f-and-fido2-usb-a-two-factor) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
