Ratings and reviews

Keeping everything secure, it does require the purchase of a physical object, an yubi key approximately $75 Canadian for the top of the line or $25 for one with limited features but once you've purchased you're on your way (one time purchase)

It is not working, it shows the codes for seconds then they disappear when inserting by USB. If you take with NFC it does nothing.

I purchased 3x Yubikeys for 2FA. They're very easy to setup & even easier to use. No keying in a digital code number each time, just a single tap with my finger on the centre of the Yubikey. The app works seamlessly with the Yubikeys, after setup & isn't even required after setup 90% of the time. This 2FA system is brilliant.
