To log in to the backend of your workspace, navigate to your site's login page. The URL of the login page is the domain of your video site with "/login" added at the end:

Video site URL:
http://video.example.com

Login page URL:
http://video.example.com/login

On the login page you will see two input fields; one for your username and one for your password. Fill in your username and password and click the "Login" button. If you have entered a correct username and password, you will be logged in and taken to the backend of your video website.

If you have forgotten your username or password, you can retrieve your login information.

Manage options in your user settings. 

Here you simply choose which sign-in options you want to activate for your site. You may also choose whether or not visitors are allowed to register for accounts themselves. You'll find the user settings here:
