Sorry, I’m unclear what “No, Ciprian’s plugin is A two-factor plugin” means; I mentioned that it does indeed provide 2FA while also remaining lightweight and fast — I should have added: “as a security plugin.” His introduction is here.
The WP plugin “Two-Factor” is listed as incompatible with CP, though there are two more plugins with “Two-Factor” in the title.
In any case, perhaps @Ciprian can explain how his 2FA function queues up during login (if that is the right expression).
