Azure-docs: What's the scope of OpenID Connect interaction with identity provider functionality?

Does OpenID Connect authorization affect API access only or can it replace the use of 'Username and password' as an Identity Provider when accessing developer portal content?

My goal is to replace Username and password with an [company] approved mechanism to authenticate (and so create or invite) a developer such that we're not storing their registration data (name & email address) in Azure. Need to be able to go beyond restricting API access to also restrict access to content in the portal (while working on a POC I'm restricting access to widget content using layer rules with "isAuthenticated" and url rules). It would currently appear that the only way of achieving this currently is using Delegation
