I open my browser and navigate to a login page. When I click the LastPass asterisk in the input field, I'm prompted to log in. I enter my password, and another tab pops open asking me for my MFA key (which I get from Google Authenticator on my phone).
However, if I go back to the form from which I triggered the login, the password is now filled in. (This site, as many others are, is set to autofill, but not autosubmit).
How is this possible? Is LastPass's MFA broken?
