I'm the owner of my CosmosDB resource. Still I don't see the "Keys" section in the left list? Why so?

@croraf Thank you for the inquiry. There should be a blade specific for managing keys:
@Mike-Ubezzi-MSFT No. I have completly different view:

And I have the owner role. Maybe it's different cosmos db version, or?
I have a mongo api btw.
@croraf The Connection String blade and the Quick Start blade can be used to source what is called a password in MongoDB API, for both Read-Write and Read-Only 'keys'. Providing you full screen captures to show you what I see:


@Mike-Ubezzi-MSFT So these Primary Password and Secondary Password are the same as master primary key and master secondary key from the section "Master key tokens" from this page https://docs.microsoft.com/en-us/rest/api/cosmos-db/access-control-on-cosmosdb-resources?redirectedfrom=MSDN ?
This is correct. The Cosmos DB for MongoDB API does not have REST capabilities so the keys simply act as a password. The username is the name of the API instance you created. The SQL API has both the SQL API and the REST API as service endpoints and the key concept is part of Access Control, per the document you referenced.
