Multiple user login

Is it possible to have multiple customers share the same customer ID? For example customer 1 has login email [email protected] and password 'abc' and under the same customer ID ("account") there is also a different customer with email [email protected] and a different password.
This way two different users from the same customer can login and see privious orders etc.

Or is there a plugin available that does this?

The first option is not available because the customer id is a unique number tied to a single email address in a default store.

Would require either a store side plugin to tie order history of one customer to another and support display of the order history or an admin side modification (potentially an additional admin directory) to allow the individual access to order history and potentially limitation on actions to be performed.

Alternatively, if only notification of orders is necessary, then it may be possible to send an email to multiple people if an order is placed by a customer as part of the order process.

Recommendation would be to further identify the need of the associated information and how much/what information is needed.

Not currently aware of a plugin that offers this capability, but would think that if the appropriate business need is identified that something could be developed.
