Yubico - Security Key C NFC - Black- Two-Factor authentication (2FA) Security Key, Connect via USB-C or NFC, FIDO U2F/FIDO2 Certified

You'll need this for Google's Advanced Security program and also for Apple's and any other company that allows for passkeys. Seems to be durable enough after a couple of month's of use. I hope the overall cost comes down as they try to push this into the market. I also wish Amazon allowed this to be used a second factor instead of codes sent by text message, but they don't at the moment.

Eigentlich habe ich den Stick nur als Backup gekauft, falls mein Handy mal verloren geht oder nicht funktioniert. Allerdings konnte ich nach der Einrichtung des Stick nun mit dem Handy nicht mehr unterschreiben; nur mehr mit dem Stick. Entweder habe ich bei der Einrichtung etwas falsch gemacht oder die Beschreibung bei ID-Autria ist "gewohnt" verwirrend; war bei der Handy-Signatur ja auch so. Ich musste das Handy also nachher wieder meinem Konto hinzufügen.

Excelente dispositivo para robustecer la seguridad

I was impressed with all the positive reviews of how wonderful Yubikey is. However, if you do not know exactly what you are doing, then wait until you have time to wade through a new technology. Understand if you delay past your return date, you might just end up with a relatively worthless device you cannot depend on. I thought I was purchasing the exact solution for my desires. However, the version I chose does not work with LastPass to provide both a security key and a backup. Since my primary desire was to lock down my password keeper, I find the Yubikey version worthless for my primary purpose. What I failed to detect in the sales material is that the "Security Key C NFC" does not have the OTP application installed. LastPass requires OTP to use a Yubikey as a back up for MFA. While I can set up passwordless authentication using my security key, I cannot register a back up security key using the Yubico devices I purchased. As a nube, I did not comprehend the finer points of this. Essentially, out of ignorance of the fine points of this technology, and my delay in getting it set up, I am out the price of four devices which do not accomplish my primary purpose. Too bad, so sad, thank you for contacting customer service. To say I am frustrated with the situation would be a vast understatement.

Easy to use. Safety is key. lol
