Esshahn on "Protected site with different logins/passwords?"

Hello,

I'm still a big newbie with WordPress, and I didn't find a solution for this by browsing the whole morning, hope you can help me:

I need a page that is only visible after a password is entered. This is easy, but what I need is to assign different passwords to different people. With the build-in function I can only set one password for everybody.

The absolute fantastic solution would be this one (figure this might be much harder, so it's optional):

1. Visitor sees PART OF the content of the page without entering a password
2. If he enters a password, he sees ALL content on that page

Any help is greatly appreciated!
Thank you all very much,
Tim
