We currently only allow one login per account. Enterprise accounts can create child accounts, which have their own identity, but don't have full access to the parent (editor) account. For example, an anchor/journalist could have their own account and their questions could get automatically picked up into the "Featured Poll" and polls page via the subscription option in Feeds. It would just show their name in the "Asked by" and their face.

If you're looking to share the single login for the main account with full rights, we typically recommend a secure password sharing solution like LastPass.

We do have an enhancement request for this and plan to allow multiple logins for enterprise accounts in the future.
