Pluggin for login registered customers

May I ask for recommendations, please, for a customers page where they need to login with their own email in order to open the page. I would like to share files just with registered customers. Besides I guess I need work with MySQL database.
Thanks for any suggestion.

The favourite seems to be SiteLok. It’s not a plug-in but they give detailed advice on how to implement it in RapidWeaver.

SiteLok rocks. Many options. Developer uses Rapidweaver. Several plugins if you need them.
