I know there is a plan for SSO for all apps here already: https://ideas.gohighlevel.com/app-marketplace/p/single-sign-on-sso
However, I would like to mention that we need SSO for Client Portals to be automatic and to turn it off and on with a switch. So if you turn it on, the client is already logged in on the iframed custom menu you link when they login to GHL and if the switch is off, the client has to login in manually.
The reason I ask this is a lot of us don't know how to implement SSO or API and it might be cumbersome and difficult to setup. So I see why you would have to manually set it up if you are using SSO for an external app but we definitely need automated setup for internal apps like Client Portals and other places that require seperate logins
