Identiv uTrust FIDO2 NFC Security Key USB-A (FIDO, FIDO2, U2F, PIV, TOTP, HOTP, WebAuth)

The keys are good and work very well. However, they do not come with instructions and the Identiv website is not very helpful. Having used Yubico security keys I knew what I wanted and was able to find Mac drivers that were necessary to enable these to work on my iMac. Also, I was able to find a beta utility for the Utrust keys that enabled me to add a FIDO password. If I had not been aware of this step I would never have known from the product packaging.These Identiv keys appear to be targeted at commercial and government use, probably the reason for lack of consumer documentation. Given this, and the fact they are made in the US, I’m guessing they are high quality products. Build quality seems about as good as YubiKey despite being slightly larger and having a plastic loop for a keychain.

I have a sturdier key with more connectivity, but needed a second key in case I lose that one. This key is much slimmer, which can be good or bad, depending what you use it for. It's less durable, but it also slots in well in my minimalist wallet.Overall it works very well, both the NFC scanning and the touch confirmation. One potentially bad aspect though is it seems to physically fit in a USB A port either way you turn it, but only powers one way. I imagine this could break something if you're not careful when inserting it.

Does not fully support Linux (no linux version of Manager software )

The title and description claim this device supports PIV and TOTP, but that is not true for this model. Only the NFC+ version actually includes those features. This standard model does not provide full PIV or TOTP functionality.If you need PIV and TOTP, make sure you specifically buy the NFC+ model. The current listing is misleading and should be corrected to avoid confusion for other buyers.

After watching a few reviews on security keys, I found this product to be durable have high reception (When transferring them to your phone), with excellent cost!Although some complained of the need to carry ‘yet another thing on your keychain’ I personally can’t understand that argument unless you’re signing in and out of your Apple account there is no need to carry them with you.One last point, with everything being electronic, in the cloud, (not physical), there leaves too much to risk from yet another breach! With security keys, you either physically, have them with you when signing out of your Apple ID or you don’t… and unless you’re allowing someone to use your account, you could have the peace of mind that no one (other than one who physically has a key) is NOT getting into your account.I definitely would encourage people his product to anyone interested.

Works good. I am glad i got this one and not expensive alternative. Only after I got it I realized that going usb stick as rxtra level of security is not for my office. Good thing it was not expensive. Product works. Was very easy to set up.

This company doesn't appear to actually very reputable. Their website for this model FIDO2 token clearly says that it's AzureAD compatible (screenshot attached), however - Microsoft does NOT list them as compatible.I was looking for a lower cost alternative FIDO2 USB key for my customers; and - this was among the lowest priced options at $15. The website says AzureAD supported - I rolled the dice. I'd say I lost, but only lost the time. It's being returned to Amazon.I tried to enroll it with AzureAD, and AzureAD says "this device type is not allowed". Weird, because it clearly sees it, and enrolls it, but fails on the final 'saving' step -- so upon digging deeper, it turns out that if devices aren't listed by Microsoft as compliant, they've blacklisted them. Microsoft tax - whatever. Identiv clearly shouldn't be listing it as AzureAD compatible without paying the MS tax.So - while it doesn't work out of the box for AzureAD; it's not non-functional. In your Security configuration for FIDO2, you can disable "Enforce attestation" -- with this disabled, the Identiv key DOES work. But - disabling this seems like a bad idea. So - Identiv goes in the trash.2 stars for something that doesn't work? It DOES actually work, it's not worthless, it just doesn't work AS ADVERTISED (implied certification). They get a point for it being functional - I assume it might work with some other things.Now - I had to figure out how to MAKE it work on my own, I couldn't find any articles on their support site about Azure, FIDO2, or really even about this key at all. When opening a support ticket, you can't select this device to open a ticket against. It's as though it doesn't even really exist.Opened a ticket against something similar (close as I could find), and after 5 days I still hadn't received any response.Then there's build quality. It's thin and really light. So thin that my USB port doesn't hold it snugly - it doesn't fall out, but there's a noticeable wiggle/movement to the USB key when the button is touched lightly. it doesn't feel like the Identiv key is going to break though; it's solid -- just too thin. I'm afraid my users would break their USB ports eventually.For comparison, I also bought keys from Yubikey ($45), and Feitian ($17); both certified, both work, and both have no wiggle in the USB port.So - sorry Identiv, I wanted to like it, but lack of support from Azure or from your tech teams made it not-viable.

This key comes at a good value if you just want a backup key for FIDO2/U2F use cases. However, it does not support Windows login, nor does it support ed25519-sk SSH keys. It does support ecdsa-sk SSH keys, although ed25519 is generally considered superior to ECDSA, so it is nonsensical that they have not updated the firmware to support both at this point.Others mentioned receiving a key without tamper-evident packaging. This was not the case for me, as mine was in a sealed package. It's certainly unacceptable for these to come in a resealable bag like others have received though, and I would highly encourage returning any that arrive as such. With that said, a good security key would not be susceptible to any sort of tampering without being physically opened (and blowing a tamper fuse in the process). If someone has the means to circumvent such protections, they can certainly reseal a package to look unopened.
