Chromecast guest mode allows your guests to cast to Chromecast without connecting to your WiFi network.
This Chromecast guide explains everything you need to know about the Chromecast guest mode: what the guest mode is, how it works, how to enable or disable it, how to cast in the guest mode, and the limitations of the guest mode.
By default, the only way to use Chromecast is by joining your device to the same network as Chromecast.
This is part of the security consideration: you don’t want your neighbor to mess up your TV screen.
Sometimes, you have some guests in the house and they want to share something interesting from their devices through Chromecast. In this case, you have to connect their devices to your network to use the Chromecast.
If you have some sensitive files in your home network, you probably are reluctant to have them connected to your network. You may trust your friends, but you cannot trust their devices which may have nasty malware.
Chromecast guest mode comes to solve your dilemma. Thanks to the recent update in Chromecast.
You can turn on guest mode on your Chromecast device so that your guests can use some (not all, see limitations below) features of Chromecast without connecting to your home network.
Once Chromecast guest mode is enabled in the Chromecast device, Chromecast will emit a special WiFi beacon.
The compatible apps (Google cast ready apps) in the guest device can detect the presence of the special WiFi beacon and shows the Cast icon in the app. Then the guest can tap the cast icon to pair with the Chromecast.
Of course, even in guest mode, Chromecast still needs to verify that the user is legitimate. The verification will be done in one of the two ways:
So, there is no security concern on enabling and using Chromecast guest mode. It is not necessary to turn it off unless you know you don’t need it for a prolonged period.
By default, Chromecast guest mode is turned off in all Chromecast devices.
You can enable Chromecast guest mode from any Android devices that are connected to the same network as the Chromecast device.
Please try to update your Chromecast app if you haven’t updated the app for a long time.
This will turn on the Guest mode for this Chromecast. The color of the switch should also change from white to dark blue.
As shown below, once the guest mode is enabled, a 4-digit PIN will be generated and displayed. This PIN will also be shown on the TV screen immediately.
On this page, you can drag the switch from right to left to disable Chromecast guest mode.
Your guest now can cast to your Chromecast without connecting to your home network.
To cast in the guest mode, please follow these steps.
If the device is in the WiFi range of Chromecast, you should see the cast icon (as shown below) after opening the YouTube app. If you cannot see this icon, close the app, move a bit closer to Chormecast and then try again.
Normally, if the guest device is close to Chromecast, pairing will be done automatically.
If not, you will be prompted with the option to type the PIN or listen for the PIN as shown below.
Once the guest device is connected to the Chromecast, a notification will be displayed on the screen with the Chromecast name.
You can cast to Chromecast in the guest mode now. You have similar control to stop casting in the notification area.
Chromecast guest mode has the following limitations:
The guest mode works with Android devices with Jelly Bean 4.3 or later versions.
You cannot use Chromecast guest mode to stream local content from a guest device. Google Cast Ready applications that send local media from your phone or tablet to the Chromecast do not work with guest mode.
Android screen mirroring is not supported in the guest mode even the guest device runs KitKat 4.4.2 or later versions.
Guest mode settings are persistent unless you manually change it or reset the device. If you want to change the PIN, you can turn it off and turn it on again.
Please leave your questions, comments, and feedback in the comment box below, if you have any questions or get any problems with the guest mode.
We will try to help you.

My guest mode worked perfectly fine until I recently updated my android to Lollipop. The cast screen image no longer shows for guest mode and I'm forced to use wifi on my phone everytime.
Which app has this issue?
Please note, screen mirroring (screen casting) is not supported for guests.
All of my Chromecast ready apps now have this issue. Including Netflix, Hulu, Hbo GO, Showtime Anytime and Youtube. They all detected Chromecast through Guest mode before and now they don't.
I can confirm the Chromecast guest mode works with Android Lollipop. I tested it with Galaxy S6 edge, Moto G 2014 (updated to Lollipop), Galaxy Note 4 (updated to lollipop). All of them work.
You may run Chromecast app once on your Android Lollipop device (it is not necessary to connect to it). After this, for the apps, you can try to clear cache and clear data, then try again.
Hello im looking for info. On how to manage the devices that are connected to Chromecast if my guest mode is off.
I live in a house full of people and I don't want them to sync with my Chromecast but they are using the same WiFi as my chromecast and my guest mode is off how do I change it so they can't cast from there devices???
Have a nice night thanks!
For Chromecast, all devices in the same network are equal. You simply cannot prevent other devices from casting to your Chromecast if they are also connected to the same network.
This is not a security bug. Chromecast is designed to work in this way. It's designed as home entertainment device, and therefore all devices in your home can access it.
I am wondering why I screen mirroring does not work in guest mode? We use this for business and I would rather not allow the WiFi to be used, but the reenactment mirroring us something that would come in very handy during meetings.
As explained in the page, Chromecast guest mode does NOT support screen mirroring.
The reason is related to how screen mirroring work. In screen mirroring, the router is involved in transmitting data between mobile device and Chromecast. But in guest mode, the devices that are not in the same network as Chromecast cannot access the router. These devices can only pass the resource URI to Chromecast and then Chromecast takes over and fetch the resource from internet.
Can the guest mode work with Chrome browser? Or this consider as mirroring which is not supported under Guest mode? Thanks.
If it is a Windows. Linux or Mac laptop, then the guest mode will NOT work.
If the past, I tested it with Chromebook and it worked. But it seems it is not working now. I need some time to check it further.
So the Guest Mode only works on "App" that is Google Cast ready? And article above stated is Android devices only?
So the same App on iPhone will not be able to work on Guest Mode as well?
Thanks.
The Chromecast guest mode works on the iPhone and other iOS devices as well.
