Yubico YubiKey 5 Nano Two Factor Authentication Security Key - Black - USB-A

I use this product on a Windows laptop and I find it to be extremely convenient. Being someone on the move, using this to generate the token is time-saving too. I'd suggest anyone who's using two-factor authentication to go for this.

Since I work in IT, let me just say one thing. After installing this for a few users, together with our ani-virus it has prevented phishing attacks 100%. We plan to provide this on more users. I will be listing things I like about the key and some things I dislike/recommendations in hopes that this will help you make a decision. Overall, I highly recommend this key and wish I would have gotten it sooner. Likes: - Made to stay in a laptop. (Do not loose the laptop) - It's easy to configure and really secure. - Small, discrete and easy to cary around. - Made in USA and Sweden. - If you have security concerns with Google or other companies. - it is not a google product, thus they will not have access. - It works with most sites and if configured properly can be used to sign-in to windows, mac or your network. YouTube will have several tutorials on how to do this. - Compared to RSA security keys, you get this at a bargain. - It's a consumer version so it is not overly complicated. - There are several security/authentication methods you may use. But, the simplest one is using 2FA (Two Factor Authentication). You can use this without giving your phone number or answering security questions (which we forget). Dislikes/Recommendations: - Not every site supports yubikey - There are additional software used to manage but takes a while before you can understand what these can do or how to use it properly. - Made for a laptop so it may be a bit difficult to pull it out. It's basically made to be kept in the laptop. 'Just don't loose the laptop. You need to attach a string or a keychain so you can pull it out easier from the usb slot. - From time to time you need to remove the key and re-insert it into the USB slot. There are also 2 points you need to consider. * Before purchasing the key, make sure that the site you will be using it supports this. Here is a list of sites which supports the key. The list keep growing https://www.yubico.com/works-with-yubikey/catalog/ * You need to purchase 2 keys. Same a a physical door key, if you loose one, you have a duplicate. It will be more difficult verifying your information if you loose a key without a duplicate.

It's a great little device for plugging into a desktop system especially. Sits nice and flush instead of having a big USB stick poking out of your system. Doesn't add any special functionality beyond that of other Yubikeys, just a much more convenient form factor for fixed systems. Works great, responds perfectly to touch, does what it's supposed to do.

it arrived on-time and well packed. this items is used for special purposes like storing secure transactions or crypto wallet. so who buy it are aware of its value. To me, it is one the best HSM in the market

I think some of the 1 and 2 star reviewers need to take more time to understand exactly what it is they're buying. Firstly, it's a MULTI-FACTOR device, it's not supposed to replace passwords (yet), hence the term MULTI-FACTOR, there are MULTIPLE FACTORS to your login procedure, the first one being your username and password, the second being this key. Secondly, it doesn't type out your password on screen, it types a cryptographically-calculated string which changes each time and is specific to the hardware key itself. The interaction of touching the device is in place to work with your chosen software when it prompts for a U2F device, where you need to press the key to activate it. This is to stop automated log ins when the key is connected, it requires a human to physically activate it. Pressing the key at any other time will output a meaningless code onto your computer, which means nothing to unconfigured software, so this is not a security risk. Thirdly, not all services support hardware keys yet. New hardware and software takes a VERY long time to be supported by all platforms and always starts with the biggest (Google, Microsoft, Amazon, Facebook, etc). You should check that the services you want to use this for actually support hardware keys. Lastly, this is supposed to be small. If you're complaining about it's size when there are other options available like the standard Yubikey 5 or Yubikey 5C, then that's your problem not the product's. This is supposed to be a static key that can be removed if necessary, such as for a personal laptop, and should be used in conjunction with another 2FA method as a fallback e.g. mobile authenticator app. This is a great product that does the job it's designed for. It's working well with Yubico Windows login software and a number of online accounts.

在宅ワークでデスクトップPCの使用がメインになったのとGoogleからパスキーを推奨するアナウンスがあり導入。 他の製品と比較してやや高価なものの、小さいためUSBコネクタに挿しっぱなしにしておいても引っ掛けて破損するといった事が無いのが安心。 念のためUSB AtoCの変換アダプタと合わせて購入しました。
