The Loginizer Team has launched version 1.6.0 with the following changes :
1) [Feature] Admin can white list an IP or an IP range for Two Factor Authentication.
2) [Fix] If the plugins or themes which are included in the default WordPress package were not updated, the Checksum reported that the files for such plugins and themes did not matched. This is fixed now.
More features will be coming in the next releases.
