Product interface with user login

Hi all!

I am desperately looking for a plugin or feature that makes it possible to create individual pages in my WordPress site that external users can log on to with their own username and password (that I manually add in the wp-admin interface), where they get access to their own page on the site in question.

For example: John Doe visits the site and presses the ‘customer login’ link on the page, whereafter he will be prompted with a logon / password window. When the credentials have been verified correctly; he gets forwarded to his personal page with the personal data the wp-admin can create / edit through the WordPress interface..

I hope my request makes sense 🙂

Thank you very much for all your input!
