Launches a login modal to authenticate with Supercast. This does nothing if the user is already logged in.


Supercast.startLogin({ subdomain })


  • subdomain - The subdomain to log into.

Detecting a login

When the user has succesfully logged in, Supercast will fire a supercast-login-state-changed event to the window DOM Object that it is hosted in.

If you're using supercast-gate to gate logged in functionality, that component will automatically refresh itself when the user is logged in.
