Hello,

1. Please remove the 2-way factor authentication from your site, then I am able to log in to your site. At this time, I am not able to log in to your site with the authentication code as well so please removed it so I will check the issue and remove the gap.

2. Please deactivate all the 3rd party plugins from the site and activate only theme required plugin, I am sure your issue will be solved.

Otherwise, send me the WP admin login details after removing the 2-way factor authentication from the site.

Best Regards.
