Amazon Grafana - possible without single sign on?

Hi,

At the moment you will need to use either SAML or AWS SSO in order to use Amazon Managed Grafana.

That said, if by SSO you only mean AWS SSO then you can use SAML as an alternative. Here is a blog which discusses this -> https://aws.amazon.com/blogs/mt/amazon-managed-grafana-supports-direct-saml-integration-with-identity-providers/

Hope this helps. Please let us know if you have may have any other queries.
