Hello Viktor

You can make one or more pages "protected". In access management you can create groups and users, and then specify which groups / users that shall have access to the "protected" pages.

These pages can then only be accessed by the users that is specified - those users has to log on with the username and password you have specified for them.

Once logged in the users will have access to all pages they are set to have access to. A user that has access to 7 pages only have to log on once to get access to "his2 pages.

As you have the PRO version there is also the "dynamic content" object.

This object will give some users right to edit some content "online".

You can on the object give the same users access to edit content the same way you give users right to access pages.

If you want to protect your whole site, you have to protect every single page on your site - but I think this is not what you mean - right?
