Works well

Really good for security enthusiasts, brilliant if you want to ensure that your security is kept to a top level.

I bought one 'Yubikey 5 NFC' which works flawlessly. I then realised that I needed a backup key, so bought the 'Yubikey Security Key', which has less functionality, but does have the 2FA for authentication so should work as a backup.I spent a whole evening faffing about with it and I couldn't get it to generate codes, so I sent it back. I left it a while and forgot about it.Recently I had a few attempted security breaches on one of my email accounts, so I decided I'd buy another and retire the authenticator app and use the Yubikeys entirely.Well, another evening faffing around trying to get it work and again I just couldn't get it to generate codes, so I sent that one back and instead bought another 'Yubikey 5 NFC' again. It took me around 30 mins to set it up and it works fine. It generates codes every time, no issues.I don't know what it is with the 'Yubikey Security Keys', but nothing I tried worked, and I tried everything!The full functionality keys work fine once they're set up, but they are a lot more expensive. I managed to get another good deal as I did with my first one.As for the security aspect; there is no 100% secure system, but I feel this is better than an app that is installed on a device that could be compromised and only generates 6 digits. Yubikeys are completely isolated and can generate around 50 digits and can in itself be PIN Code protected, plus all the other security features available on the 5 NFC.I won't go into all that here as some of it I'm still figuring out and probably won't ever need as a general user. Some of the features are for enterprise users for company computers and entry systems, etc.These keys are independent of each other and not linked or cloned in any way, I'll add the new key as an additional one to each account Inhabe that supports them and PIN code it and stash it somewhere safe.

Super.
