YubiKey NEO

I got it for ₹3,000. Not sure why the price is so high now.I received a sealed and new product. There's no gripe on this product. YubiKey Neo is an all-in-one product from Yubico. It as NFC, two different storage & host of other features. You must read it's documentation for supported products & services on their site.It's a must for infosec & privacy professionals. Also for those who think they are being spied, or targeting by regimes.

Does the job perfectly well.

Perfect security

Worth the money so far. I also bought some more cheap ones for backup.

awsome

NICe it is very useful for account secure and it is very very simple easy use no words to reject it

All my commits are signed as long as I have it plugged in.With gpg-agent, I can use passwordless login on SSH servers, as long as I have it plugged in.I can access/edit all of my passwords in `pass` (gpg encrypted password manager) as long as I have it plugged in.All of this with the smartcard functionality alone.I log-in to university lab machines with the static password functionality, which used to be extremely annoying to get out my phone and type the long generated password. Just plug it in and hold the button.Previously tried using one-time-passwords, but ended up being not convenient and insecure on my phone. I'd end up forgetting they were stored on my phone and wipe it for an update, losing all of my OTPs.Now they're always there at a tap against my phone or an app on my desktop.And U2F is OTPs but even more convenient. Works a charm on Chrome on Android over NFC if you have Google Authenticator installed as well.No issues or bugs run in to. Just worked on any OS or system I've tried it on without any hassle.These security tokens are security without the loss in convenience. Very worth the money.

Sono anni che uso la Yubikey per proteggermi online. E devo dire che funziona benissimo. E' indistruttibile. Sta bene agganciata al portachiavi e la versione NFC dialoga con i dispositivi mobili. Raccomandata a chiunque voglia elevare il proprio livello di protezione.

Le token parfait pour l'authentification à deux facteurs. Gère aussi bien le FIDO que les OTP avec un smartphone NFC. Possibilité de protéger le token avec un mot de passe. Petite subtilité pour ceux qui utilisent Google Authenticator : celui-ci stocke la clé privée sur le téléphone lui-même, alors que l'app de Yubico exploite le token. En cas de perte / piratage du téléphone, les credentials sont toujours protégés, puisque vous possédez toujours le token.

製品自体には満足しています。実装されているほぼ全ての機能を使用していますが、大変安定動作しています。他の人が書いているようにNFCはあまり使いませんが、あって困る機能ではないので。しかし、この製品の後継機種が本国で発売されています。"YubiKey 5 NFC"が新しいモデルです。FIDO2やRSA 4096 (PGP)、ECC p384対応が追加され、キーホールにも変更があるようです。（削れ防止？）近いうちに国内に入ってくるでしょうから、急いでいない限りこの製品を買うべきではないです。

*** INTRO ***The YubiKey NEO has really set the bar for where these types of devices need to be heading. Many improvements have been made, additional support has been provided, and the device itself has proven to be functional, durable, and secure. I'll just go over some of the basic aspects of the NEO and point out some of the important aspects of the device.*** WHY BUY IT? ***I think the first question many people ask is, "why do I need this?" It really all depends on what type of information you need/want to protect. If all you do is browse the internet, not making any online payments or using any services that require a secure password, there's no need for a YubiKey. If you're using LastPass or another program designed to save all of your passwords in one spot using a "master password", you don't necessarily need a YubiKey, although I'd strongly recommend it, especially after the notorious "Heartbleed Bug" hit the news.The Heartbleed Bug is a very serious OpenSSL vulnerability that allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet.)I was originally introduced to the NEO when I was searching for a security key that would help protect my Google account and services. U2F was a necessary service so that narrowed the list down quite a bit. I originally looked at the cheaper keys but settled on this one mainly because of its versatility in terms of usage. I now use it for LastPass in addition to several other services, including several services with 3-step verification (password, challenge question, YubiKey.)***WHAT IT STORES ***The YubiKey come with two (2) configuration slots which I use for OTP and U2F (downloading the NEO Manager is needed to set up U2F and it's a program you'll want to have anyway.) U2F is supposedly the security protocol that the industry is headed towards, although at the moment, only Chrome OS, version 38 and up (right now we're on Version 41) and a couple other services use the U2F protocol.*** SETUP ***Setup is literally plug-and-play for the most part, unless of course you need to enable advanced features, in which case you would download the YubiKey Manager software.*** LAST PASS ***YubiKey and LastPass work together so well, it seems like they were meant to be the combination of choice for 2-step authentication. I use the NEO for my LastPass account and it works great but honestly, as much as I love the functionality of LastPass, I wouldn't trust relying on it by itself unless it was secured by the NEO, too; Just entering a single "master password" in LastPass is not enough security in my opinion. LastPass also supports NFC which is great when using it on your mobile devices. More on the NFC functionality, below:*** NFC (Near Field Communication) ***The NEO makes good use of NFC (Near Field Communication) where you simply tap the NEO to the back of your Windows or Android Phone and the phone will sense and read the key, and you're good to go! Only iPhone 6 and iPhone 6 Plus support NFC so if you're using an older iPhone, you want have this functionality. As another reviewer pointed out last year (and is still the case as of 3/29/2015), U2F is not supported with NFC. I'll update the review if/when it is.*** UNABLE TO UPDATE YOUR YUBIKEY NEO ***Due to security reasons, YubiKey does not allow for the NEO to be updated should updates be released so whatever your current YubiKey supports is all it will ever support. I understand the reasoning behind this but it would be pretty annoying to buy a NEO and then a couple months later, the new ones are being shipped with updated firmware, supporting additional features.*** I'll update the review if any new information is available. If you have a question not answered in the review, let me know in the comments section and I'll try to find out for you. ***
