The shared password manager is used constantly by me and my team, but we are constantly running into the issue of one of us having the Authenticator associated with one of our clients accounts when servicing and needing them to authenticate for us. Sometimes they're busy, sometimes they don't see it, sometimes they deny it, and even worse, they're positively reinforced for accepting it without double checking it's one of us.

A centralized shared authenticator would be a fantastic feature.
