Thetis 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

I’ve been using the Thetis Pro Key for about a month, and I genuinely feel more secure online. Setup was straightforward—it worked flawlessly with both my Google and Microsoft accounts. It’s compatible with Windows, macOS, and even Linux, which is perfect since I work across different platforms.The build quality is excellent—it’s aluminium, not cheap plastic, and feels sturdy enough to survive daily use. The USB-C and USB-A connectors are a nice touch, especially since I use multiple devices.Its obviously FIDO2 certified, meaning it uses strong, phishing-resistant security. No more worrying about SMS codes or authenticator apps being hacked. I even tested it by trying to log in from an unknown device without the key and it blocked me, just like it should.Tip: Make sure you register it on multiple accounts and keep a backup key stored safely in case you lose it.Overall, this is one of the best purchases I’ve made for digital safety. If you care about online security (especially if you're in business, IT, or finance), this is a must-have.

If you are like me you first think that this a ledger for storing your crypto currencies but it is nothing like that at all. This is just an authentication device that you would use to give you an extra layer of security when using two factor authentication. or even multi-factor authentication depending on how many layers of security you really want. For my needs and for the information I hold, two-factor authentication is more than enough.The reason why this Pro-C FIDO2 Security Key Passkey Device is so good for two-factor authentication is because firstly it's a physical hardware device that without it nobody can access your accounts AND secondly because it uses advanced authentication standards like FIDO2 and TOTP/HOTP, making it an excellent choice for securing your digital identity. To be honest I don't really understand how these authentication standards work, and you really don't need to know the workings of them either. You just need to appreciate that this has great features that provide really strong protection. It makes sure that only authorized users can access their accounts, protecting against phishing attacks, account takeovers, and other security threats. It integrates the various authentication methods across various platforms in order to keep your accounts secure across them all.All you really need to understand is that once you have this device installed, it acts like a physical hardware key, giving you an extra layer of security for your digital accounts, ensuring that only you can access your accounts as you are the only one who will have this hardware key that you associate with you accounts when you install it.This key is supposed to make things easier than other hardware keys as it also offers finger print authentication, but that part is not great as it is really hit and miss when letting you in as I don't think it has been implemented properly - well either that or it has a fault with it, and is also the reason why I have given this 4 stars.

This proved the only way to access our old US-based accounts from the UK as we didn't have US mobile phones for text codes any more. Simple. Easy. Tick.

Great physical security device for 2FA authentication.I have only used this for some less important accounts (Google and Facebook). But honestly, I feel like Tom Cruise in Minority Report every time I use this.It works extremely well, and needing to have a physical device to access your account is a game-changer. I plan to use this on LastPass when I eventually get around to using it more.It has wide compatibility across multiple devices and browsers, too.Will update this review as I go.★★★★★ - Excellent--My ratings explained:★★★★★ - Excellent: Outstanding product, exceeds expectations in all aspects.★★★★½ - Very Good: High quality with minor imperfections, almost perfect.★★★★☆ - Good: Solid product, generally reliable with room for some improvements.★★★½☆ - Above Average: Performs well but has a few noticeable flaws.★★★☆☆ - Average: Adequate, meets basic needs with visible areas for improvement.★★½☆☆ - Fair: Below expectations, issues that impact user experience.★★☆☆☆ - Below Average: Major issues, underwhelms in most areas.★½☆☆☆ - Poor: Significant problems, needs substantial improvement.★☆☆☆☆ - Very Poor: Fails on almost all counts, highly unsatisfactory.

Awful experience. Firstly downloading the manager is a task in it's self kept "couldn't download contains a virus" slightly worrying for something supposed to keep you more secure. Eventually got around this by turning off all Chrome Browser Safe Browsing and Windows Defender. Then there's the hassle of opening it! Again had to disable Windows Defender and open as Admin. Right I thought should be ok... No this is as far as you get the software recognised the key was able to set a PIN and then since I haven't been able to actually register it. Google seems to have removed its security key management within Chrome and also hidden the option to add to your account under 'Passkeys' when wanting to add to your Google account. Unable to register it with Microsoft or Windows 10 Login. NFC doesn't appear to work on Samsung s25 despite downloading app and having NFC on. Really it's terrible - not sure if mine is faulty. I will be returning it as it's clearly not being picked up despite using different ports. Frankly whilst cheaper then other keys I wouldn't bother - this is not worth the money at all as it doesn't work. Smaller than shown/expected which is good.

Ive got to b honest i dont knowHow to use i it no indtructions notg ood
