Very small product packing a lot of features !

Reviewed in the United States on April 24, 2023

Verified Purchase

Delivery overseas was insanely fast.
There are a lot of feature, and a lot of possibilities for your security set up.

For a basic usage, it is quite fast and intuitive to configure. I appreciate how small it is for a key meant to be left permanently attached to my laptop.

The “finger touch” interface works surprisingly well, but could be improved. For Linux, the companion app could be better integrated with the OS for a faster, easier unlocking of the device using pinentry or something…

Overall, a complete security solution for a very low price. Not forgetting that this is the only one I found with a backup feature ! I recommend.

TOTP Requires Companion App

Reviewed in the United States on July 6, 2022

Verified Purchase

After discovering this device I was hopeful it would support TOTP on its own but unfortunately that is not the case. TOTP requires a companion app to be installed on the PC/Mac for time keeping. This reliance is buried in documentation but it would have been super helpful to be mentioned in the product description. The device seems to work fine otherwise but it does not fit my needs for TOTP.

it has possibilities but poor construction

Reviewed in the United States on May 10, 2023

Verified Purchase

The device is a good idea, but in implementation it falls short. The handles used to remove the device is flimsy and breaks easily. Additionally the fit is very tight so this causes the handle to break. This is poor engineering and it should have never been sold with such weaknesses. It does work but with its flaws it is nearly a waste of money. It would seem they did not test this out much. If they could improve the engineering and get it to work consistently it offers great possibilities.

The instructions are worthless just like the DUO device

Wonderful security key

Reviewed in the United States on March 16, 2023

Verified Purchase

I’ve been using this key daily on Ubuntu for about 5 months now. The linux version of the configuration software was easy enough to get running. Sometimes the settings don’t automatically apply when making changes, and you have to re-apply them. Not sure why this happens, and it’s fairly infrequent.

My main complaint with this is the BRIGHT LIGHT. The LED on the device cannot be turned off. It can be turned down in brightness through the settings app, but even the lowest brightness is rather high. This problem is increased because it defaults to green (which our eyes are most sensitive to), and there doesn’t seem to be a way to change which color it starts on initially.

Other than that, it’s been a fantastic product. A whole lot of configuration options and the key seems sturdy enough. I hope they release a low-profile USB-C version at some point (like the Yubikey 5C Nano, which I also own).

Small warning to laptop users: a problem with these sort of keys (Yubikey suffers from this as well) is that since it’s entirely touch-based, it’s easy to accidentally activate the key without intending to. I really wish a company would make a key with a tactile activation button.

Neat compact tool

Reviewed in the United States on August 23, 2023

Have been using daily for last 6 weeks, I like it over the larger model a lot more since it’s so much smaller and doesn’t snag in my pants when removing my keys

Good idea but bad durability

Reviewed in the United States on July 23, 2022

After placing the below message Cryptotrust reached out to me and is sending me replacements, So I am raising my rating. I like the device but the support was difficult.

Previous message:
I have been using my Onlykey DUO since April 22 in May 22 when I went to use it none of the LED came on.

I have tried to contact Onlykey and Cryptotrust the vendor several times via their Contact us on their site, using the support forum, Kickstarter, and email for the past month and I have received no response.

I worked in Computer Security at a fortune 50 company and suggested using the Full Onlykey for some limited access. The Full Onlykey provides some controls but has no centralized management isn’t FIPS compliant, does not enforce password rotation, or certificates. The Duo less so. While we have used he Duo it didn’t hold up and the vendor hasn’t provided any support.

It’s a great little security gadget

Reviewed in Canada on January 13, 2023

Verified Purchase

Once you get the hang of it, it does the job really well. It can be annoying to handle in the beginning as the buttons are tiny. Not for the impatient. After using it for a week, it is now really easy to use. The trick is to barely touch the edge of the buttons or use a pen or another sharp object. Been able to use it on both laptop and cell is a great advantage. Great defense against keyloggers. Overall really happy.

A small hardware key with a lot of options

Reviewed in the United Kingdom on July 2, 2022

Verified Purchase

I’ll start with a disclaimer; I’m a software developer. This device is exactly what I was looking for and provides a lot of control, but it could be overwhelming for less technical users. There are more simple products which still provide very good security.

With that out of the way, this device is amazing. It has the usual hardware key functionality (FIDO2/U2F/WebAuthn) which gives very secure authentication with a single tap. Unfortunately, many websites don’t support these standards and TOTP (Google Authenticator) is more popular. That’s okay, because you can register a slot on this key to type the six digits, much like it can with a password!

It has 6 slots per profile with 4 profiles, so 24 slots in total. Each slot can store a URL, username, password and a 2FA key.

All of that and it’s secured by a pin which you can put into the device itself, which will protect you from keyloggers. If you’re not worried about that, you can type the pin into the app too.

For the nerds, this key has its own support for SSH and GPG keys. I prefer to use the U2F functionality in the newer version of SSH, but both work well.

A few things you should know:
– TOTP only works if you’re running the app (also available as a web app) because the key needs to know the time. Not a big deal, just something to be aware of.
– The minimum pin length is 7 digits. This is probably reasonable on the original OnlyKey, but it’s fiddly on this one. If your dexterity isn’t great, you’ll have a bad time. You can put it in on the app instead, but the original OnlyKey and an OTG adapter might be better suited to you.
– There’s no mobile app. You can use the web app, but this only provides the time to the device (for TOTP) and message/file encryption.

Even with those caveats, I’m really happy. I don’t think there’s another hardware key which ticks the same boxes as this one.
