A nice security enhancement, and easy way to do 2-factor authentication.

Overall I give these one HUGE thumbs up, and would recommend them to anyone that would like to add a little dual-factor authentication into their life.~May your security be easy, and your encryption be strong.

So the Yubikey 4 is a simple product that offers great security (assuming you don't lose it)

Once I set up my key with Yubico Pluggable Authentication Module (PAM) and ensured it was working properly, I tried defeating the security

Not only do I not need complicated passwords anymore, but now these accounts are only accessible with this key

Anyone who's serious about using multifactor authentication to protect your online accounts should consider getting this device

and i did everything to secure my accounts before i purchased these

I use these with last pass to protect my online accounts.

I also understand that Google employees use these to help keep their accounts secure.

If you're planning on using OpenPGP follow the instructions carefully, I personally recommend having a dedicated PGP key for you YubiKey rather than trying to modify an existing one, it's a pretty easy setup otherwise.

It is simple to use and setup was easy with my accounts

The setup and configuration is easy to follow and has been consistent ever since.

YubiKey 4 is the best and a perfect solution to your security needs.

As plenty of reviewers have pointed out, it isn't a good solution for Apple users and the Linux setup is tricky for novices.

In general the PIV support is more usable than other PIV smart cards I've used.

Setting it up to work as a PIV smart card is a pain, simply due to Certificate Authority issues with EFS/Bitlocker; however, easily remedied using command-line instead of their PIV Manager GUI.Zero problems with U2F.

This security key has the ability to maintain two two security access methods, e.g., Smart Card and

Setting it up to work as a PIV smart card is a pain, simply due to Certificate Authority issues with EFS/Bitlocker; however, easily remedied using command-line instead of their PIV Manager GUI.Zero problems with U2F.

I haven't used the two-factor features much, but have been very happy with the PIV smart card application and the PGP support.

A nice security enhancement, and easy way to do 2-factor authentication.

This conceptually is a great piece of hardware, but being made of plastic, it falls short in one important way.. its far from indestructible

That said, it's still a decent way to prevent unauthorized access to your PC/laptop though there are much better ways to do it, and without using 3rd party programs (e.g. adding a signed CA giving it access to the EFS and adding Bitlocker's usage extension OID to the certificate).

Love it, you probably don't need this newest nicest one, but I do strongly recommend getting two, and configuring them with your services at the same time, that way if the key is lost or stolen you don't have to jump through password recovery hoops.

Didn't work as expected - it may be a knockoff

That worked as expected, once I watched a quick video on how to configure the software and key

Works as expected, though I would like to upgrade to yubikey with NFC capabilities later.hope that I don't loose it, I cannot find a way to replace it if the key has been lost.

Always worried about hitting the thing accidentally and breaking it.

Certain things work on the front USB ports, while other features do not.

Yubikeys are Awesome, I use them for all kinds of neat things.

The only complaint I have about this Yubikey 4 is that it's so tedious finding all the cool things you can do with it

Buying a YubiKey finally convinced me to two-factor all of the accounts, a good thing, obviously.

This Key is well made out of a hard plastic that can take a total beating without cracking, and always works without fail.

The only product that is easy to implement for security as long as what ever your securing supports this key.

I recommend getting a backup key or if your spouse or partner uses one, register both keys on each other's account.

Works great with LastPass, I would recommend this key for people who want to use this with PGP

Confusing advertising seems to indicate that it is 4 keys!

I believe the advertising was deceptive in its support for iPad and iPhones.

Works as advertised and expected, I hope more providers adopt Yubikey and 2 factor authentication

That is if the yubikey is lost or malfunctions, you will not be able to access your account/data -- naturally this raises the question of how to protect the second yubikey

If you have a grudge against Chrome then you better get the Yubikey 4 as it works with other browsers as long as they support it

I like the YubiKey but have a problem switching between my Mac and Windows machines

The Yubikey makes it extremely difficult to crack the password on the LastPass, so the other Internet passwords remain protected in LastPass and protected from other users on the network.

Also, the YubiKey works well in conjunction with a Nexus tablet and an OTG cable

I am not sure how much of this the Yubikey can simultaneously handle (due to poor documentation it isn't readily apparent to me)

Pros: many supported protocols for almost any servicesCons: poor documentation

I realize that Yubico is a security company and has ubergeeks but they should probably consider hiring someone who could write more user-friendly documentation.

Also, while I'm up here griping, the documentation was pretty bad

Due to poor documentation I am still not sure what a slot is
