Yes.
The backend login is controlled via your current AWS creds: default profile, explicit profile (AWS_PROFILE=xyz), whatever.
The in-Pulumi (resource-creating) provider uses whatever creds you tell it to use. If you don't supply a provider, that's the default creds, same as the backend. If you need different creds, just create an instance of aws.Provider and pass it to the resources via the opt provider (or providers, which is a map, and the key would be "aws").
No matter how you like to participate in developer communities, Pulumi wants to meet you there. If you want to meet other Pulumi users to share use-cases and best practices, contribute code or documentation, see us at an event, or just tell a story about something cool you did with Pulumi, you are part of our community.
