Hi @photonmarisbest2 ,
The desired flow you describe sounds like one that can be configured straight out of the box with the feature.
I am not sure I entirely understand the existing flow you describe but do note that Organizations is only supported when using it with New Universal Login, more information here.
I recommend the following settings within the Auth0 Tenant -
Navigate to the application > Organization Tab, and ensure that its set to “Business Users” this will then block users that do not have membership to an organizations.
Then select the “Prompt for Credentials” option for login flow.
Lastly, you may want to set the authentication flow to identifier first if using enterprise connections (You may need to enable at least one database connection if the identifier field does not show).
With these settings, when the user is directed to the New Universal Login widget they can login, and if just a member of a single org will get directed straight to that org, or if a member of multiple will have the option to choose from listed options.
Hope this helps!
