This is a complete edit/rewrite because I think my previous explanation was unclear
I would like to enable logons from another site. We have clients with a complete SSO to a portal that we use. This portal gives clients access to multiple systems that we have in place for them, without them having to log on a second time.
How would I implement this with Backendless UI Builder? I could pass credentials from the portal to Backendless, but what would be a best practice to handle such a thing?
