Yes please. +1
please please please please please i just don’t want to go back to boxee
I too would love the PArental Control feature, but I think it should be implemented in at least 2 ways; 1st, based on the MPAA rating associated with the movie, TV Show…2nd, by content section.
That way, for those of us that have a single movie folder that holds all our movies, we can restrict which movies are/are not accessible w/o a PIN/passcode.
+infinity for this feature in any capacity 
Perfect +1
This would be awesome to have! I really like the graphics made by r3dlink13.

Are we just talking to ourselves here… This thread has been around well over a year and still nothing in the way of parental controls. Plex is awesome, but completely impractical if you have young children. Until there are parental controls, I will be using the Boxee 
+1, but I doubt it will do any good… I’ve seen many such requests over the years, it just doesn’t seem to be something that the plex developers care about. It’s a shame, really… Plex is the best media solution around, but is in many ways crippled by the lack of basic functionality present in other solutions.
+1 please guys, I know you have it marked for the 1.0 milestone, but it would be great to bump it up.
+1 for me too…this would be outstanding to have for the Windows Server too!!!

We have talked over parental control far away from the topic. For children's control, keylogger and time limit software is good.
Yup we really need this!
If the Plex team would do this it would definitely persuade me to join “Plex Pass”…right now, I can’t see doing it when they don’t support something as simple as this. People have been wanting it for the longest time. It cannot be that hard to do. Why don’t they do it? I dunno.
Maybe we’re just waiting for one or more of the Plex devs to have kids so they understand the huge need for this feature? When you’re a 20 something single young adult, or dating/married without kids, then parental control isn’t an issue. Heck, you might even still feel some resentment towards the entire concept stemming from your teenage years. However, once you have kids then your entire attitude on this changes.
Would I love to turn my 5/12 year old loose on Plex so he could watch all of his animated movies and browse through the kid oriented video channels? Heck yeah! I’d spend my $4.99 on the Plex for Android app in a heartbeat to put it on his new tablet he’s getting for Christmas. But in its current state, I can’t let him anywhere near my Plex server on his own. Just let me set Plex to default at a certain MPAA rating for movies visible to the client, and a check box list for installed video channels and I’d be happy.
Just put a pin code or password choice in the main Plex Client menu so it would be consistent across all clients, and then once entered that client will now show all content. Input in the pin code or password once again, and it reverts to its previous locked down and child friendly state. I mean really, wouldn’t all this be doing is changing how you view a database?
I just downloaded/installed PMS on my one Windows media server and PMC on the system connected to the TV. I am trying to move away from Windows Media Center (Win7). I was hoping that each library/channel could have a PIN number attached to it, plain and simple. That does not appear to be the case.
So…
+1 is my upvote on that. We really need that in Plex ASAP. I am willing to pay for it now, and if the PlexPass makes it possible then I will sign up for that. I am not looking for anything complicated, just the same pin-level protection that would come from a settop box and other Plex alternates out there.
Thanks.
This is still falling on deaf ears, not even a comment from a Plex developer since 2009 !!!
Incredibly frustrating such an important feature can be ignored for years, maybe Plex itself should have an 18+ rating to stop all the complaints / requests over the consequent years for parental controls or pin code content access 
I’d even be happy for a clumsy / crude hack to the player where-by it checks first to see if the media has a certain collection assigned to it (e.g. adult).Anything would be better than nothing!
+1 It's the perfect way to implement the Parental Control. All the most important Media Center software have implemented some form of protection for kids and I was totally surprised when I discovered that this feature is missing in PLEX. Till this feature will not be available I will not use this product at home, sorry.
+1 and more....
this request is open way too long! Seems the devs have other priorities. Untill this is fixed I'm not feeling like buying the pass...
+1
I'd buy a second lifetime pass for this feature
+1 on this. I just bought a Roku 2 XD last night and Plex is going to be by-far the most used feature of this thing in my household outside of Netflix. We're planning to get 2 more boxes, one for each of the children's televisions so they can watch movies/tv in their room during the summer. While my kids have seen the many violent and gory movies I've watched before...I don't really like the idea of them accessing "Nightmare on Elm Street" on their own at night or when they have friends over.
Being able to lock movies by rating AND lock specific folders would be awesome. I too, would buy a lifetime pass if they could implement this feature.

Made an account to say this is the one thing that I really really want in either Plex as a whole (preferred) or PleXBMC (as this is what is running in the youngest viewer's room at this time). I would PAY for this feature! I have only recently begun to use Plex and at this point I have avoided adding R rated movies and similar content to my Plex server library simply because there is no way to lock it. The rest of the household would love to be able to browse everything, including the more mature materials, in Plex but for the time being we are at either grab the disk and watch that or access the movies in lower quality using competitor software PlayOn (which I had been using for various things before discovering Plex) which we have not set up to be accessible from the little one's media PC.
