Is there any way to keep using the WP login form? I use a 2-factor authentication for certain roles but this is not supported by the Pie Register login form. Despite the activated 2-factor auth, the login is possible just with username and password.
To use WordPress default login, please uncheck “Do not allow users to login from WordPress login page.” from “Pie Register > Setting”. Please see the screenshot below: http://prntscr.com/i7ilpo
