Product Specifications: U2F protocol: Universal Second Factor service that allow user to add a strong second factor device to user login.

Size and weight: compact usb flash drive size and lightweight design. Review: Compact and effective - I'm an Internet Engineer, and I've been building infrastructure for media companies for nearly 25 years. I know firsthand that companies don't care about your data as much as they care about saving money, so protecting yourself is up to you. Google issued hardware keys like this one to all of their employees, and after doing so, they were immune to phishing attacks. If you want to be sure that the hackers behind the next data breach can't access your accounts even if they get your password, then a U2F key is the way to go. U2F keys activate the "something you have" of two-factor authentication, complementing the "something you know." There are a number of ways to deliver 2FA - authenticator apps with one-time passwords, text messages or emails with codes in them, RSA-style dongles with the six digits that change every minute, or a U2F key like this. The nice thing about a U2F key is that it _complements_ another form of 2FA. If you don't have your phone with you or left your RSA dongle at home, having a U2F key on your keychain means you can still access your accounts, and vice versa. You can even activate multiple U2F keys, whereas sites only allow a single OTP or authenticator app. Always have a backup for important things. I set it up with Dropbox and Google Apps, and it only took a moment. This key is small enough to go unnoticed on my keyring, and I like that it folds to protect the USB connector. I have another key from a different vendor that doesn't offer protection for the connector, and I'm concerned about how long it will last, flopping around in my pocket. The key from Thetis feels solid, and I'm glad that I bought it. How small is it? I've added a couple of pictures to show you how it looks with a USB-C adaptor in my Mac, a pair of AirPods, and a standard folding-style USB flash drive. It's tiny. Support for U2F is new, but as more sites recognize that they can protect their users by enabling support for it, it will become more prevalent. I recommend that you pick one of these up and activate it everywhere that you can. Review: Once you try the FIDO U2F Security Key you wont want to use your Authenticator unless your on the go without your FIDO U2F key! - RE: FIDO U2F Security Key, Thetis This U2F key is the one to have laying on the desk in a small, horizontal usb hub, where it is thick enough so as to not wobble downward and stress it and the hub too. This key works great and flawlessly btw; I put a Yubi UF2 Key that is setup for all the same accounts on my key ring, for portable needs, but at the office (in a secure environment) or at home this is the one to have on the desk in a four port hub because it's thick enough not to rock downward when pushed so it doesn't stress anything in the process of pushing the 2FA button downward. These U2F keys are vastly less of a hassle and much more simple and easy to use compared to Authenticator (2FA) and all it's competitors where one has to look up a code on their phone or tablet and then input that one time code into their PC for 2FA. These are also way more secure in many ways than Authenticator and it's competitors is while setting up such a thing, as well as relying on many servers at many companies not to be compromised are all security risks! As always have a backup key ready in case you lose your working key! Compared to using Authenticator with this I just push the button on this usb key and instantly your most secure 2FA type of method is done with this physical U2F usb key instead of say with Authenticator! It doesn't get any better than these for the highest 2FA security as long as you can control who has access to your usb FIDO U2F Security Key. Once you try the FIDO U2F Security Key you wont want to use your Authenticator unless your on the go without your FIDO U2F usb key! Leave Authenticator for a backup and use this at home and in the office, you will be glad you did just like me if you do! ## Features - Protect Online Account - Offer a strong factor authentication to your online account.

Will this work with lastpass?** A: Does LastPass support FIDO/U2F authentication with Yubikey? We currently do not. Once FIDO/U2F is supported in all major browsers (the U2F standard is currently only supported by the Chrome browser, with Firefox support in beta), we will add LastPass support for this MFA. Please see the bug report for Firefox here - and post your request to add this support. In the mean time, users can configure their keys to Mode 6 to work with both as mentioned here If your key does not support an OTP mode, it will not currently work with LastPass. **Q: I have two gmail accounts, how many fido sticks do i need to protect two gmail account. do i need to buy 2 ?** A: you can use one key with multiple accounts https://support.google.com/accounts/answer/6103543?hl=en **Q: Is this company a known and reputable company for this type of security?** A: So, I was trying to research this company. They have a website. That seems like it. I can't find Thetis on Linkedin (who is the CEO of Thetis?), they don't have any social media presence, their website has opaque domain registration. They AREN'T listed on the Fido Alliance website, as a lot of other FIDO keys are. I contacted them for support yesterday and haven't heard back (seen other people say the company is unresponsive). The more research I do, and the less info I find, the more nervous I am about using this product. **Q: Does it work on android?** A: Since this is a USB-A FOB, you would need an adapter that goes from USB-A to USB-C or Micro-USB, and there are no guarantees that with an adapter it will work. (Some do, and some don't.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Compact and effective *by A***S on January 23, 2019* I'm an Internet Engineer, and I've been building infrastructure for media companies for nearly 25 years.

Works great. But, remember the number of devices that support U2F is pretty low. Works out of the box in Windows Chrome, Linux requires additional config to get going. It should be noted that this key works for Chrome on Windows; however, it does NOT work for login. If you get the 1903 Windows 10 update, you can log in with a security key; but for my Thetis key it said "this device is not supported". I assume this is because only "FIDO2" devices are supported and this product is "FIDO U2F". FIDO2 supercedes FIDO U2F and FIDO UAF. If you want it for Windows 10 login, look elsewhere. For Linux (Mint at least) the login does work though. It also survived going through the laundry, so that's something. (Reasons to have multiple keys). Also, as you're setting up the keys, I highly recommend disabling SMS authentication otherwise your key is pointless. SIM card dropping is the reason I got my U2F keys ## Frequently Bought Together - FIDO U2F Security Key, Thetis [Aluminum Folding Design] Universal Two Factor Authentication USB (Type A) for Extra Protection in Windows/Linux/Mac OS, Gmail, Facebook, Dropbox, SalesForce, GitHub - 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 - Identiv uTrust FIDO2 NFC Security Key USB-A (FIDO, FIDO2, U2F, PIV, TOTP, HOTP, WebAuth) --- ## 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.com.ar/products/43758817-fido-u2f-security-key-thetis-aluminum-folding-design-universal-two](https://www.desertcart.com.ar/products/43758817-fido-u2f-security-key-thetis-aluminum-folding-design-universal-two) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-13*
