I won't explain what it does, I presume folks know it's for higher login/data access above and beyond passwords. Other than standard two factor logins with a key. Fido, fido2 and u2f are pretty well covered. Yubico, a company that drives the above standards extends those to additional protocols, a yubico authenticator app that works in conjunction with the key. Nice. This key, like others you'll find for sale away from the manufacturer may have older key firmware with a bug or improperly implemented feature. Keys are updated periodically. But they can't be updated in the field due to security issues. So the key I got was on a firmware from about a year ago and is missing a few profiles added to some security protocols I don't use. Next...note you should have 2 keys for backup, but they don't have to be the same, not do you need two of these 5 series yubico. I got this and a cheapo but we'll functioning basic key for ten bucks. So if the yubico breaks, I can use the cheapo backup until I receive the replacement yubico key.Read full review

I already have older versions of the Yubikeys, but I needed a NFC version. They work great for securing computers, programs, or online access. Just make sure you have an alternative access method in case you lose it. The price was better then buying one key directly from Yubico.

This is my second key (backup). I have not had any issue but overall It's only been about three or four months since I started using the keys.
