How can we share our cluster control with multiple users?

Much like we deal with AWS and having multiple users with IAM permissions defined we want to share our clusters within our group. Right now the owner is the only account with access to even see the cluster. Is there a way to have more than one person with access to the portal itself (not the cluster)? Being limited to a single user seems like a problem as does sharing the credential (for audit purposes) with every user who might need to login.

Is this a Cloud question?
