I am a Lastpass premium user. Great product you have.
To use Lastpass I must first log on to it, and then because I use 2FA, I must also touch my YubiKey.
That makes sense for most things. However, the process repeats itself if I close my browser and open it up again (at least the YubiKey part) so it can be a little distracting, esp. if my YubiKey is not plugged into my USB port.
In any case, when I am not signed on but need a quick password generated (one that I may decide not to store in LastPass), I first need to sign-on to Lastpast, and only then can I generate the password. It would be better if the option was available to generate a password without having to first log on.
