creating a single author page for multiple authors?

We’ve created a magazine in WordPress with “Stylish Mag” theme. Since its a magazine many different people will be writing pieces, but only two of us will actually post them to the magazine site.

Right now, to create author profiles? for each person who writes a piece for the magazine, we have to create a separate author profile, username, and log in for each author. We would like to not have to create a separate username and log in each time someone new submits a piece.

So on the front end, it would mean the byline (author’s name) would be a link that would take the reader to a dedicated author page for that specific author (with a short profile and a list of articles written by that author), or a running one page for all the contributors (when the byline is clicked the reader would be directed to a page that has a list and bio of all contributors to the site).

Does anyone have any suggestions?
