Hi @vics,
Welcome to the Auth0 Community!
I understand you want to know how to enable SSO when using Organizations.
Firstly, SSO works by default with Organizations enabled or disabled. However, if your Customers anticipate using Enterprise Connections such as Azure AD, then you will need to own an Enterprise License.
Lastly, please be aware that toggling on the Display Organization Prompt in your Organization settings will prevent SSO and force the user to submit their Organization name, email, and password to log in.
If you have any further questions or concerns, please reach out, and I’d be happy to help.
Thank you.
