Feature Request: Time-locked access to passwords

This timed access is a great idea for a very practical access control, i.e. for systems which should only ever be accessed within specific times such as business or operational hours.

Ideally these systems would be completely inaccessible, for which there do exist some solutions for certain cases, but limiting access to identification and authentication would substantially limit inappropriate access by otherwise legitimate users.
As for how to implement this on the clients, that's an engineering problem. 😆
