Pro-C FIDO2 Security Key Passkey Device with USB C & NFC, TOTP/HOTP Authenticator APP, FIDO 2.0 Two Factor Authentication 2FA MFA, Works with Windows/macOS/Linux/Gmail/Facebook/Dropbox/GitHub

Today when I used my key, it broke. The connector broke away and remained attached to the usb port and the key broke in two. This is a very dangerous situation. The build quality is poor. I have a backup key or I'd be in big mess

I am not affiliated with the company and my review is based on my own experience: The Thetis Pro-C FIDO2 security key has impressed me. The construction feels solid and well-built; actually more sturdy than my YubiKey 5C. Setup was straightforward, and it works flawlessly with my Linux system. I use it not just for login, but also to input my sudo password in the terminal, and even as a trigger to lock the computer when removed, which works perfectly. It’s also a great tool for encrypting and decrypting a LUKS-encrypted Linux hard drive, making the system both safe and easy to use without compromising security. Just make sure you keep a backup security key, in case something goes wrong. On Linux, the key can be used for several additional security tasks. It works well with SSH for passwordless login using hardware-backed authentication, can integrate with PAM modules for system-wide authentication, and can be used with GPG for signing and encrypting emails or files. It also supports browser-based FIDO2/WebAuthn logins, making it useful for securing accounts like Google, Amazon, and others. I haven’t been able to test Windows Hello login as I don’t use it, but it works perfectly on macOS too. It also performs reliably on my phone, which adds to its flexibility. The specifications are strong and everything functions as expected. The only thing I’d like to see in the future is firmware update support, but honestly, as it is now, it’s already a brilliant and dependable tool.

I've been using the Thetis Pro-C FIDO2 key for a while now, primarily for basic two-factor authentication, and I'm quite satisfied with its performance. While I haven't explored all of its advanced features like TOTP/HOTP, everything I need it for works flawlessly. I use the Thetis Pro-C alongside a Yubico key, and I honestly can't tell the difference in speed or basic functionality. Both keys perform equally well in securing my accounts. This makes the Thetis Pro-C an excellent value proposition, offering comparable performance to more expensive brands at a more affordable price point. Pros: - Reliable FIDO2 performance - Comparable speed and functionality to Yubico keys - Excellent value for money Cons: - None at the moment * I haven't tested all advanced features! Overall: If you're looking for a reliable and affordable FIDO2 security key for basic two-factor authentication, the Thetis Pro-C is a great option. It offers solid performance and is a great alternative to more expensive brands. *** Top tip for those who say NFC doesn't work: *** The protective bracket that the key rotates in is made of metal (aluminum), which blocks the NFC chip. You must therefore unfold the key before you can scan it. This is a bit annoying at times, but on the other hand, it offers an extra layer of security.

I’ve been trying out the Thetis Pro-C FIDO2 Security Key, and my initial experience has been positive. Setup with USB-C and NFC worked smoothly, and the device responded consistently during my authentication tests. I also appreciate that it supports TOTP/HOTP, which gives me more flexibility across different accounts. The first thing I noticed was the build quality. In my opinion, the design feels more refined and substantial compared to some other security keys I’ve used. The metal housing gives it a more premium feel in the hand, and the overall fit and finish look thoughtfully put together. The LED indicator is subtle and blends well with the design—nothing flashy, but it has a cleaner and more modern appearance to me. The device also feels secure on a keychain without being bulky. NFC worked reliably during my early tests, and tapping into mobile authentication felt intuitive. As with any security device, I’ll continue testing it over time, but my first impressions are that it delivers a good balance of durability, aesthetic appeal, and functionality. So far, the Thetis Pro-C strikes me as a solid choice if you want a security key that not only works well but also feels well-made. I’ll update my thoughts if anything noteworthy comes up with longer use.
