Is there any way to put a password on your sonos system?

Didnt you just indirectly answer the password question yourself here? If you could find the "password" for the wireless system then correct your could do that.

Sonos is basically saying that they dont care about a corporate market... they dont want to be in restaurants, hotels or cafes.... pretty flippin STUPID.... I own a gallery and have spent the whole flippin night re-setting up speakers and re-setting playlists.... i gave the wifi password to the lessee of the event space and they gave it to everyone else!   Half the time the music was down with everyone playing with the sonos or keeping the wifi too busy to buffer music!

Millions of ways around this issue as has been stated by myself and others. Its a nice to have to ultimately not a limiting factor to anyone buisness or private purchasing. I suppose takes a little know how but anything can be worked around. If you like any suggestions or ways to circumvent anyone messing with it more then happy to help. Can go from super easy to as complicated as you like. I will through this out there, many devices on the market today has dual wireless functionality. The "main" and "guest". Put one of those devices in place, only allow guests to use guest and you never have a problem. And that is just one option.

There are many features we would all like to see on the Sonos, personally I don't see this one hitting the development list. But who knows. If you don't trust people on your network, the options are, A) don't give them the password. 😎 bar them by mac address if they already have it. Not foolproof I know, but a solution. C) Create a guest network for those 'friends', boyfriends, lesees, postman, next doors dog who is abusing yours, but for some reason have to have wifi access. D) Change your wifi password and then find new friends, dog, etc. Remember, if these users/guests are changing your Sonos system, just think what else they may be doing! That would scare me. As Thomas said, many answers to what is really a non-problem, just a nice to have. Lets be honest, if Sonos spent time and money will it generate business benefit, possibly , but not much in reality. I would personally prefer they spent their resources elsewhere. Just my 2pennies. 🙂 Graham

I am okay with PW protecting my network to keep people out, however I am using the Sonos Bridge so Im assuming they don't have to log into my WIFI network and can just log into the Bridge, and we all know they will.  Hell I would at their house.  Am I wrong about this, meaning do they still need my Wifi PW to access the Bridge or can any Sonos APP'd device connect to the Bridge and control my music? 

Only Android devices have ability to log directly into SonosNet.

I'm for an option you can activate "Party Mode" that if active only controllers that enter password can get full access.  Non-password activated controllers only get ability to add to que.

Only Android devices can log onto Sonosnet, and they first have to connect to your WiFi, then connect to Sonos in order to do it.

I now put Sonos 1, 3, 5 and connect in most of our house but since most friends know we have sonos, they constantly change music. People are requesting an option to protect their sonos since more than 3 years. Will you finally do something or will you just watch people leaving Sonos for something that has access control? This should have been on your priority list since a long time
Solution is to create a separate network for Sonos. Limit access to that network.

Well I must say that there are some damn fool answers on here in relation to 674433's, Anthony's, TK's and John's fairly simple request. It only occurred to me after I'd bought my Sonos that this could be done (ie trusted guests to whom one's given their wifi password messing with your settings). I won't go to the bother of returning my kit in the "cooling off" period, 'cos I like it too much, but it obviously is an issue that Sonos would do well to address, before it becomes the subject of negative reviews.

Hello, There isn't a way to set a password or limit accessibility of the Sonos system. If someone has an iOS or Android device and is able to connect to your main network and gone through the setup process with the Sonos application they will have access to the system.
Their are some songs you may not want your wife or kids to see right? May have to remove them until you can protect your privacy with a password.
