Warning Message on White Label URL
Is your browser such as Chrome or Safari showing you a warning message on your white label login page? The is likely because you're not using the HTTPS version of the page. A simple way to change this is to add "https" before your login URL. For example, if your login page is http://login.mycompany.com you would then change it to https://login.mycompany.com. After that, you're all set!
Have a Great Week!
