Depending on how your white label system is setup, the login form on the /login page might be hidden by default. For example if your users are only allowed to login using SSO.
If you’re an administrator, you might need to login using a traditional username and password authentication scheme.
To force show the login form, simply append ?force=true to the end of the URL.
For example: https://yourwhitelabel.com/login?force=true
