I'm in agreement with all others on this thread - QBO should definitely add the ability to integrate with other identity providers (Google, AzureAD, or any SAML provider). Sure it is great that Inuit has an Oauth 2 system for integrations, that makes sense for sure, but the support people in this thread and elsewhere in the developer pages aren't getting that we IT administrators are also looking for a way for our QBO end users (our accountants, etc) to sign into to QBO using the identity provider that our company uses for literally everything else.
