Different login credentials to one account

Is there a feature in CB that allows login with different emails addresses/usernames and different passwords, but to one account only?

I tried searching in the forums, but I am not sure what to search for.

Or even an option where I can register 2-4 email addresses that can be used for the same account.

Nope on all questions.

Thank you. Not what I wanted to hear though.

How about linking different accounts maybe?

Joomla needs unique emails for its accounts.

Each account has one username and one password.

The features you are looking for are really missing in Joomla.
Suggest you explore / ask for them on the Joomla forums.
